The incredible story of Roboute Guilliman, from loyal Primarch of the Ultramarines Adeptus Astartes to the Imperium of Man’s Lord Commander and Savior in Warhammer 40k!
Updated January 9th, 2025, by Rob Baer with new information and links to relevant content.
So, you’ve heard the name Roboute Guilliman tossed around 40k, haven’t you? Maybe it was during a heated debate about who’s the real MVP of the Imperium, or perhaps someone mentioned him while lamenting their last crushing tabletop defeat.
Either way, Guilliman’s rise from the Ultramarines’ poster boy to the Imperium’s ultimate boss is nothing short of legendary. He’s not just a Primarch anymore—he’s the Imperium’s shining beacon (and occasionally, its most stressed-out workaholic). Let’s break down how this larger-than-life figure went from leading the boys in blue to leading literally everyone!
A Heroic Rise
Roboute Guilliman—the name sparks debates, reverence, and even the occasional meme across the Warhammer 40k universe. He’s the Ultramarines Primarch, the Imperium of Man’s most logical leader, and a figure whose return has reshaped the galaxy.
Whether you’re into the lore, tabletop battles, or just admiring the sheer scale of Warhammer’s narrative, there’s no ignoring Guilliman’s impact. Let’s dive into his resurrection, rise to Lord Commander, and what it means for the Imperium today.
Resurrection and Return: A Turning Point for the Imperium
Roboute Guilliman’s resurrection is one of the most pivotal moments in Warhammer 40K history. Once thought lost to the ages after his near-fatal duel with Fulgrim, Guilliman’s return was nothing short of miraculous—or controversial, depending on who you ask.
In a galaxy rife with corruption, betrayal, and existential threats, the revival of Guilliman offered a glimmer of hope to the Imperium of Man. Using advanced technology combined with the raw power of Eldar magic, Belisarius Cawl and Yvraine, a key figure in the Ynnari faction, orchestrated what seemed impossible. Guilliman rose from stasis, ready to face a galaxy that had spiraled far beyond the meticulous order he once envisioned.
The reaction was mixed. While many hailed him as a savior, others questioned the cost of using xenos sorcery to restore him. This tension between tradition and innovation is central to Guilliman’s journey as he grapples with a crumbling Imperium that seems allergic to change.
Guilliman’s Resurrection Story: Logic vs Chaos
Roboute Guilliman’s resurrection isn’t just a cool plot point in 40k—it’s a testament to his character. As the Ultramarines Primarch, Guilliman always embodied structure, strategy, and the belief that humanity could thrive through discipline and planning. When he returned, he found an Imperium he hardly recognized: stagnant, riddled with inefficiency, and clinging to outdated dogmas.
Imagine waking up to find your meticulously planned empire in absolute chaos. That’s Guilliman’s story in a nutshell. The Imperium of Man had become a parody of itself, with rampant bureaucracy and zealotry overshadowing any real progress.
Guilliman’s first order of business was to implement his signature logic and practicality, but doing so while navigating the crushing weight of the High Lords of Terra, the Ecclesiarchy, and countless other factions proved to be as difficult as facing a Chaos horde.
The emotional weight of his resurrection is also key. Guilliman wasn’t just angry; he was disillusioned. The Emperor, whom he revered as a near-godlike figure, had left humanity to its own devices for 10,000 years.
Guilliman’s interactions with the Emperor after his return are a gut punch—his father figure is a silent, almost lifeless entity, far from the inspiring leader he once was. These moments of doubt and frustration make Guilliman one of the most relatable characters in 40k, despite being an 11-foot-tall genetically engineered warrior.
The Lord Commander of the Imperium of Man
After his resurrection, Roboute Guilliman didn’t just step into the role of a military leader in 40k; he became the Lord Commander of the Imperium of Man, effectively taking on the galaxy’s biggest administrative headache. His leadership isn’t just about commanding armies—it’s about rebuilding an entire civilization that’s teetering on the edge of collapse.
One of his first major initiatives was the Indomitus Crusade, a galaxy-spanning campaign designed to stabilize the Imperium in the wake of the Great Rift’s creation. This wasn’t just a show of military might but a desperate attempt to reconnect fragmented worlds and fortify humanity’s defenses.
Guilliman brought with him the Primaris Space Marines, a significant upgrade to the Adeptus Astartes, thanks to the work of Belisarius Cawl. The introduction of these advanced warriors added a new layer of strength to the Imperium’s forces, but not without some skepticism from the more traditionalist chapters.
Guilliman’s leadership style stands out in the 40K universe. Unlike the dogmatic rulers around him, Guilliman operates with a clear head and a long-term vision. He’s not just fighting wars—he’s planning for the survival of humanity itself. This pragmatic approach is both his greatest strength and his biggest challenge, as it often puts him at odds with the more fanatical elements of the Imperium.
Take the Ecclesiarchy, for example. Guilliman openly struggles with the concept of his own deification as a living saint. For a man driven by logic, being worshiped as a divine figure is about as appealing as a Chaos incursion. Yet he understands the power of faith in uniting the Imperium’s countless billions, so he treads a careful line between embracing the people’s reverence and maintaining his own grounded ideals.
And then there’s the personal cost. Guilliman’s role as Lord Commander isolates him in ways even his status as a Primarch didn’t. His closest allies are few, and his sense of duty leaves little room for anything resembling personal fulfillment. Guilliman’s journey isn’t just about saving the Imperium—it’s about navigating the crushing loneliness that comes with carrying the weight of an entire galaxy on your shoulders.
Roboute Guilliman: The Ultramarines Primarch Who Rewrites the Rules of the Imperium
Roboute Guilliman isn’t just a name whispered in the corridors of the Imperium of Man in 40k—it’s a force that shapes the destiny of a galaxy constantly on the brink of annihilation. As the Ultramarines Primarch, his story has captivated Warhammer 40K fans for decades, from his origins as a master tactician to his improbable return as the Imperium’s Lord Commander.
Whether you’re painting miniatures, diving into Codex lore, or navigating his pivotal moments on the battlefield, Guilliman’s significance looms large.
Who Is Roboute Guilliman?
Roboute Guilliman isn’t your average Space Marine Primarch in Warhammer 40k. Born on Macragge, a world obsessed with order and efficiency, Guilliman quickly rose above his peers, mastering governance and military strategy at a young age. He didn’t just lead; he redefined leadership, turning Macragge into a flourishing stronghold of culture and military might.
As the Primarch of the Ultramarines, Guilliman’s influence extended far beyond his legion. Known for his logical mind and unrelenting focus, he penned the Codex Astartes, a guide that became the blueprint for the Adeptus Astartes and their operations across the galaxy. This wasn’t just a rulebook—it was a lifeline for an Imperium struggling to maintain order in a universe overrun with chaos, xenos, and heresy.
But Guilliman’s story isn’t all about structure and tactics. He’s a character riddled with complexity. While his rigid adherence to logic often sets him apart from his more impulsive Primarch brothers, it also isolates him, adding an emotional weight to his leadership that makes him one of Warhammer 40k’s most compelling figures.
Why Guilliman Matters in Warhammer 40k
In the sprawling lore of Warhammer 40K, where titanic battles and apocalyptic stakes are the norm, Roboute Guilliman stands out not just as a warrior but as a visionary in 40k. His return during the Gathering Storm storyline was nothing short of seismic, and for good reason.
The Imperium of Man, once a shining example of human dominance, had become a shadow of its former self. Bureaucracy, superstition, and relentless invasions had left humanity teetering on the edge of collapse. Guilliman’s resurrection wasn’t just a plot twist; it was a lifeline. His return brought a renewed sense of purpose to an Imperium that desperately needed leadership rooted in strategy rather than blind faith.
As the Lord Commander of the Imperium, Guilliman faces the impossible task of uniting a fractured galaxy. His leadership during the Indomitus Crusade is a testament to his tactical brilliance, rallying Adeptus Astartes, Imperial Guard, and countless other forces in a coordinated effort to stabilize humanity’s domains.
Whether it’s leading Ultramarines or navigating the political minefield of Terra, Guilliman is a figure who represents hope, even when the odds are stacked against him.
Guilliman’s Significance in Adeptus Astartes Lore
For fans of the Adeptus Astartes, Guilliman isn’t just the Ultramarines’ Primarch—he’s the spiritual backbone of the Space Marines as a whole. His Codex Astartes remains the definitive guide for how Space Marine Chapters operate, influencing everything from combat tactics to the organizational structure of their fleets.
While some chapters bristle at the rigidity of Guilliman’s codex, it’s impossible to deny its impact. The codex ensured that the Adeptus Astartes could adapt to the fragmented nature of the Imperium’s struggles, creating a system that allowed even the smallest chapters to punch far above their weight.
Guilliman’s strategic foresight is what makes him such a standout figure in Space Marines lore. He didn’t just create warriors; he crafted a system that could survive the unrelenting chaos of the 41st millennium.
Roboute Guilliman Height
If you’re wondering, “How tall is Roboute Guilliman in 40k?” the answer is—very tall. As a Primarch, Guilliman towers over ordinary humans and even standard Space Marines. Standing at approximately 11 feet tall, he’s a giant among giants.
In the miniatures game, this translates into a model that stands head and shoulders above most units, reflecting his commanding presence both on and off the battlefield. His height isn’t just about intimidation—it’s a visual representation of his status as one of the Emperor’s chosen sons.
Roboute Guilliman Death
Roboute Guilliman’s death—or rather, his near-death—is one of the most pivotal moments in Warhammer 40K history. Struck down by his traitorous brother Fulgrim during the Horus Heresy, Guilliman was mortally wounded but not entirely lost.
His body was placed in stasis, suspended in time, while the Imperium mourned the loss of one of its greatest leaders. Fast-forward to the 41st millennium, and Guilliman’s “death” became a temporary setback. Thanks to the efforts of Belisarius Cawl and a little Eldar magic, Guilliman was resurrected to lead the Imperium through its darkest days. Death, it seems, wasn’t ready for the Primarch of the Ultramarines
Guilliman Mode: A Warhammer 40K Powerhouse
For those who enjoy Warhammer 40K on the tabletop, Guilliman is a game-changer. His datasheet showcases a combination of durability, tactical support, and raw power that few other characters can match. In “Guilliman mode,” he’s a centerpiece unit capable of turning the tide of any battle, whether through his devastating attacks or his ability to buff surrounding units.
Beyond the stats and rules, Guilliman also stands as an iconic figure for collectors and hobbyists. From JOYTOY action figures to stunning artwork, his presence in the Warhammer 40K universe extends far beyond the tabletop. Whether you’re admiring his towering model or laughing at the latest 40k Roboute Guilliman meme, his influence is everywhere.
Roboute Guilliman’s Age
Roboute Guilliman’s age is a bit of a tricky question. Born over 10,000 years ago during the Great Crusade, Guilliman is technically ancient. That said, his time in stasis after being wounded by Fulgrim means he didn’t experience the full passage of those millennia.
Functionally, Guilliman remains in his prime, though his long absence from the galaxy means he’s grappling with the weight of history that passed him by. Whether you count his years in stasis or not, Guilliman is old enough to have seen humanity’s golden age—and to witness its current struggles firsthand
Roboute Guilliman: From Macragge to the Ultramarines’ Legendary Leader
Roboute Guilliman’s story begins not with the grandeur of a galactic empire but on the rocky, disciplined world of Macragge. Born as one of the Emperor’s Primarchs, he was part of a grand experiment to create superhuman leaders capable of uniting humanity.
While his destiny was extraordinary, his early years on Macragge laid the groundwork for the leader he would become, both as the Ultramarines Primarch and the future Lord Commander of the Imperium of Man.
Birth and Early Years on Macragge
Guilliman’s arrival on Macragge wasn’t exactly a planned event. Like the other Primarchs, he was scattered across the galaxy by the forces of Chaos in an attempt to derail the Emperor’s plans.
Unlike some of his brothers who landed on hostile or desolate worlds, Guilliman’s fate was kinder—though not without challenges. Macragge was a planet of strict order and relentless ambition, shaped by a culture that valued discipline and progress above all else.
Adopted by Konor, a noble and leader of Macragge, Guilliman’s innate brilliance quickly became evident. Even as a child, he possessed an extraordinary intellect, far surpassing those around him.
His ability to understand complex systems, both in governance and warfare, set him apart. By his teenage years, Guilliman wasn’t just a leader-in-training; he was a reformer, reshaping Macragge’s society into a model of efficiency and prosperity.
But not everyone welcomed his changes. Konor’s political rival, Gallan, sought to undermine Guilliman’s vision for the planet. When Gallan launched a coup, Guilliman’s response was swift and decisive, showcasing his tactical genius and ability to inspire loyalty. By the time he reached adulthood, Guilliman had turned Macragge into a beacon of stability in a galaxy plagued by turmoil.
Rise as the Ultramarines Primarch
When the Emperor of Mankind finally reached Macragge during the Great Crusade, he found not just a lost son but a leader who had already mastered the art of governance and war. Guilliman was reunited with the Emperor and given command of the Ultramarines, a legion of Adeptus Astartes that would become synonymous with his name.
Under Guilliman’s leadership, the Ultramarines became the largest and most disciplined of all the Space Marine legions. While other Primarchs were known for their fiery tempers or unorthodox tactics, Guilliman approached every campaign with methodical precision.
His goal wasn’t just to win battles but to create lasting stability across the Imperium of Man. Where some of his brothers sought glory, Guilliman sought structure, a trait that defined his leadership style.
One of his most significant contributions during this time was the creation of the Codex Astartes. This massive tome detailed strategies, tactics, and organizational guidelines for the Adeptus Astartes.
The Codex Astartes wasn’t just a manual; it was a philosophy, one that emphasized adaptability, discipline, and the efficient use of resources. While some of Guilliman’s brothers chafed at the idea of codifying warfare, the Codex became the standard for Space Marine chapters across the Imperium.
Guilliman’s Ultramarines also embodied his vision for a sustainable Imperium. Unlike other legions that relied heavily on their Primarchs for leadership, Guilliman’s delegation skills ensured that his officers could operate independently. This decentralized approach allowed the Ultramarines to maintain order across vast territories, making them one of the Imperium’s most effective forces during the Great Crusade.
A Leader Defined by Challenges
Guilliman’s early successes didn’t come without their trials. As the Ultramarines Primarch, he often found himself at odds with some of his more volatile brothers. While he respected their unique abilities, Guilliman struggled to reconcile their impulsive actions with his own commitment to logic and order. His relationship with Primarchs like Lorgar and Angron was fraught, underscoring the tension between his disciplined approach and their more chaotic tendencies.
The Horus Heresy tested Guilliman like never before. When the galaxy erupted into civil war, Guilliman faced the monumental task of holding the Imperium together in the Emperor’s absence.
Operating from Ultramar, he established the Imperium Secundus, a temporary measure to preserve humanity’s future. While his intentions were noble, this decision sparked controversy among his peers, particularly those who viewed it as an act of treason.
Even after the Heresy, Guilliman’s challenges didn’t end. His fateful confrontation with Fulgrim, the Primarch of the Emperor’s Children, left him critically wounded. Though his injuries placed him in stasis for millennia, Guilliman’s legacy as the Ultramarines Primarch continued to shape the Imperium. His writings, tactics, and philosophy became a cornerstone of Space Marines lore, influencing countless chapters and leaders long after his fall.
Roboute Guilliman and the Great Crusade: A Masterclass in Leadership
Roboute Guilliman’s name is synonymous with order, discipline, and strategy, all traits that made him indispensable during the Great Crusade. As one of the Emperor’s twenty Primarchs, Guilliman wasn’t just a participant in this galaxy-spanning campaign—he was its architect in many ways. His ability to balance warfare, governance, and long-term planning placed him among the most respected figures of the Imperium of Man.
Role in the Great Crusade
The Great Crusade wasn’t just a military campaign—it was a vision for the unification of humanity under the Emperor’s rule. For Guilliman, it wasn’t just about crushing alien species or heretics; it was about building something lasting.
When Guilliman joined the Crusade after being rediscovered by the Emperor on Macragge, his focus wasn’t solely on battlefield dominance but on ensuring that the Imperium’s conquests would endure.
The Ultramarines, Guilliman’s legion of Adeptus Astartes, played a critical role in this effort. They weren’t just soldiers—they were administrators and builders. Guilliman ensured that every planet brought into compliance under his command didn’t just fall in line but thrived as part of the Imperium’s broader structure.
His territories became a shining example of stability, often referred to as Ultramar. This region of space, ruled by Guilliman and his Ultramarines, became a microcosm of what the Imperium of Man could achieve when logic and structure triumphed over chaos and superstition.
Guilliman’s Achievements During the Crusade
Roboute Guilliman wasn’t the type to seek personal glory, but his contributions to the Great Crusade were impossible to ignore. The Ultramarines became the largest and most adaptable legion, a testament to Guilliman’s leadership. They weren’t just known for their numbers but for their discipline and efficiency, traits that mirrored Guilliman’s own personality.
One of his most significant achievements was the conquest and integration of hundreds of worlds into the Imperium. Guilliman’s approach to planetary compliance stood out among his brothers. While some Primarchs relied on sheer brute force, Guilliman was a master of diplomacy, governance, and strategy.
He understood that crushing a rebellion or overthrowing a tyrannical regime was just the beginning. The real challenge was ensuring those worlds became functional, contributing members of the Imperium.
Ultramar wasn’t just a collection of compliant planets; it was a thriving empire within the Imperium. Its success wasn’t just due to Guilliman’s military prowess but his ability to inspire loyalty, implement sustainable systems, and create a model that others could replicate.
His worlds were prosperous, his armies strong, and his people loyal—a trifecta of success rarely achieved in the grim darkness of the 41st millennium.
Contributions to the Adeptus Astartes
While Guilliman’s achievements during the Great Crusade were impressive, his contributions to the Adeptus Astartes left a lasting legacy that shaped the Imperium for millennia. At the heart of this legacy is the Codex Astartes, a comprehensive guide to Space Marine tactics, organization, and operations.
The Codex Astartes wasn’t just a book of rules; it was Guilliman’s vision for ensuring the survival of the Adeptus Astartes and the Imperium itself. He believed that no single entity should wield unchecked power, not even the legions of the Adeptus Astartes.
The Codex proposed breaking down the massive legions into smaller, more manageable chapters, each consisting of roughly a thousand Space Marines. This reorganization, while controversial at the time, became the foundation for the modern Space Marine chapters.
Guilliman’s Codex Astartes didn’t just address military structure. It detailed everything from battlefield strategies to the psychological conditioning of Space Marines. Guilliman’s approach was holistic, aiming to create warriors who were as effective on the battlefield as they were in the broader context of defending humanity.
Beyond the Codex, Guilliman’s influence on the Adeptus Astartes can be seen in the Ultramarines themselves. They became the standard by which other chapters were measured. Known for their adaptability, discipline, and loyalty, the Ultramarines embodied Guilliman’s ideals. While some chapters resisted the strictures of the Codex Astartes, even they couldn’t deny the effectiveness of Guilliman’s methods.
The Horus Heresy: Leadership in Chaos
The Horus Heresy wasn’t just a civil war; it was the galaxy’s most catastrophic sibling rivalry, and Roboute Guilliman found himself squarely in the middle of the chaos. As the Ultramarines Primarch, Guilliman played a critical role in preserving what he could of the Imperium of Man while the galaxy burned. His actions during this period highlight his strategic brilliance and the weight of responsibility he carried, even as the Imperium fractured around him.
Guilliman’s Actions and Decisions During the Heresy
When Horus Lupercal, the favored son of the Emperor, turned traitor, Guilliman and the Ultramarines were far from the central conflict. Stationed in Ultramar and overseeing the Imperium’s most stable region, Guilliman had limited options to intervene directly. But being cut off didn’t mean sitting idle. Guilliman took stock of the unfolding disaster and made decisions that would shape the Imperium’s survival.
The creation of Imperium Secundus was one of Guilliman’s boldest moves during the Heresy. With the Ruinstorm cutting off communication between vast swaths of the galaxy, Guilliman feared that Terra—and the Emperor himself—had already fallen.
Instead of succumbing to despair, he established a secondary Imperium in Ultramar, designed to act as a backup plan in case the original Imperium collapsed entirely. It wasn’t an act of rebellion but one of practicality, aimed at ensuring humanity’s survival.
This decision wasn’t without its controversies. Guilliman’s actions drew the ire of other loyalist Primarchs, most notably Lion El’Jonson and Sanguinius, who questioned his motives. Was Imperium Secundus an act of loyalty, or was Guilliman positioning himself as the Emperor’s replacement?
The debates between the Primarchs added a layer of tension to an already volatile situation, but Guilliman remained steadfast in his belief that his actions were necessary.
The Ultramarines’ Role in the Heresy
While other legions were torn apart by internal strife, the Ultramarines stood firm under Guilliman’s leadership, and he cemented his name as a level-headed Primarch. They didn’t just defend Ultramar—they fortified it, turning the region into an unassailable bastion of order amidst the chaos. The Primarch’s strategic acumen was on full display as he used the Ultramarines not just as warriors but as builders, ensuring the survival of the Imperium’s most stable sector.
The Battle of Calth was a turning point for the Ultramarines during the Heresy. Betrayed by the Word Bearers, led by Guilliman’s bitter rival Lorgar, the Ultramarines and their Primarch faced devastating losses. Yet, Guilliman rallied his forces and turned the battle into a symbol of resilience. Calth was both a tragedy and a testament to Guilliman’s ability to adapt under pressure, solidifying the Ultramarines’ reputation as the Imperium’s backbone.
Roboute Guilliman in Modern Warhammer 40k: The Return of the Primarch
Roboute Guilliman isn’t just a relic of the Great Crusade or a figure confined to Space Marine legends—he’s one of the few Primarchs actively shaping the galaxy in the grim darkness of the 41st millennium.
Guilliman’s return to the Imperium of Man has reinvigorated Warhammer 40K lore, making him a central figure in the ongoing struggle against Chaos, xenos threats, and the Imperium’s own internal rot. From his influence on modern Space Marines to his pivotal role in current events, Guilliman’s presence is impossible to ignore.
Influence on 40k: Roboute Guilliman Lore
The story of Roboute Guilliman’s resurrection has become one of the most talked-about events in Warhammer 40K history. For millennia, the Ultramarines Primarch was thought lost, his body preserved in stasis after his near-fatal duel with Fulgrim, the Daemon Primarch of the Emperor’s Children.
Enter Belisarius Cawl, the ever-ambitious Archmagos of the Adeptus Mechanicus, who devised a way to heal Guilliman using a mix of ancient Imperial technology and Eldar magic channeled by Yvraine, a leader of the Ynnari.
This fusion of science and sorcery raised eyebrows (and bolters) across the Imperium. Guilliman himself was deeply conflicted about the methods used to revive him, but he had little time to dwell on it. The galaxy was in chaos, fractured by the emergence of the Great Rift—a warp storm that split the Imperium in two. Guilliman had no choice but to take up the mantle of leadership, stepping into a role even larger than his legendary status as the Ultramarines Primarch.
Guilliman’s resurrection also reignited interest in his writings, particularly the Codex Astartes. Space Marine chapters that had drifted from his teachings found themselves reevaluating their methods, while others doubled down on their adherence to his doctrines. The Codex became more than a military guide—it became a symbol of Guilliman’s enduring legacy and his ability to adapt his ideals to the Imperium’s current needs.
Roboute Guilliman Datasheet
If you’ve got Guilliman in your Warhammer 40K army, his datasheet is the key to unlocking his full potential. Roboute Guilliman isn’t just a heavy hitter—he’s a strategic game-changer. His rules make him a force multiplier for Adeptus Astartes units, buffing nearby Space Marines with rerolls and other benefits that turn even standard units into formidable threats.
He’s not just about support, though. Guilliman brings devastating attacks in melee, durability that’s tough to crack, and abilities that keep him in the fight even when things get dicey. Whether you’re fielding him in a competitive match or for casual games, his datasheet ensures he lives up to his legendary reputation.
His Role in Current Events
Guilliman’s return couldn’t have come at a worse—or perhaps better—time. The 41st millennium is a mess, and the Imperium of Man is barely holding itself together. From the corruption of the Ecclesiarchy to the 
unending threats posed by Chaos, Tyranids, and Orks, Guilliman’s task as the Imperium’s Lord Commander is nothing short of Herculean.
One of his first acts was to launch the Indomitus Crusade, a massive military campaign aimed at stabilizing the Imperium and reconnecting its fractured territories. The Adeptus Astartes played a key role in this effort, bolstered by the introduction of the Primaris Space Marines—another of Cawl’s controversial creations.
Taller, stronger, and more advanced than traditional Space Marines, the Primaris warriors were initially met with skepticism by many chapters. Guilliman’s endorsement of the Primaris program helped to legitimize them, cementing their place as a vital part of the Imperium’s defense.
Guilliman’s leadership style in the 41st millennium is marked by pragmatism and frustration. He openly clashes with the Imperium’s more dogmatic elements, particularly the Ecclesiarchy, which insists on deifying him as a living saint.
Guilliman’s logical mind finds such reverence baffling, and his interactions with the Emperor’s silent, near-dead form have only deepened his sense of isolation. For Guilliman, the Imperium isn’t the shining beacon of humanity’s potential he once envisioned—it’s a broken system that needs constant triage to survive.
That said, Guilliman’s impact has been profound. His strategic genius has allowed the Imperium to reclaim lost territories and hold the line against overwhelming odds. His personal presence on the battlefield is nothing short of awe-inspiring, with his abilities in “Guilliman mode” turning the tide in countless conflicts. Whether through his datasheet in the game or his lore-driven feats in novels, Guilliman remains a figure of unmatched power and intellect.

His leadership has reshaped Warhammer 40K lore, and his actions continue to ripple through the grim darkness of the far future. Let’s dive into some of the burning questions about Guilliman and what his legacy means for the Imperium and beyond.
FAQs About Roboute Guilliman
Is Guilliman the Only Living Primarch?
Roboute Guilliman is no longer the only active Adeptus Astartes loyalist Primarch in Warhammer 40K lore. With the awakening of Lion El’Jonson, the enigmatic leader of the Dark Angels, the Imperium now has two loyal sons of the Emperor influencing its fate.
Guilliman’s resurrection and leadership as Lord Commander of the Imperium marked a monumental shift for humanity, but the Lion’s return has added a new layer of complexity—and much-needed support—to the loyalist cause.
Lion El’Jonson, who had been in stasis deep within the Rock, is now awake and ready to take up arms against the enemies of the Imperium. His leadership style contrasts sharply with Guilliman’s pragmatic and systematic approach.
Where Guilliman focuses on rebuilding and restructuring the Imperium, the Lion’s methods are shrouded in mystery and marked by a more personal, knightly sense of duty. Together, they form a formidable force, though it remains to be seen how their differing philosophies will play out on the galactic stage.
Beyond these two, other loyalist Primarchs remain either missing or inactive. Vulkan of the Salamanders is believed to be wandering the galaxy, his perpetual nature ensuring he could reappear when least expected. Meanwhile, the fates of other loyalist Primarchs, like Corvus Corax or Jaghatai Khan, remain uncertain, though whispers of their potential return persist.
On the traitor side, several Chaos-aligned Primarchs continue to wreak havoc across the galaxy. Figures like Mortarion, Fulgrim, and Magnus the Red remain active threats, twisted by the powers of the Warp and commanding vast armies in their bid to destroy the Imperium. Guilliman and the Lion face an uphill battle, but their combined presence offers hope in a universe teetering on the brink of annihilation
Where is Roboute Guilliman now?
Roboute Guilliman is currently stationed on Terra, the heart of the Imperium. As the Lord Commander, he oversees military campaigns, governance, and the endless task of holding the Imperium together. His role has become even more critical with the emergence of the Great Rift, a massive warp storm that has split the galaxy in two.
Guilliman’s presence on Terra isn’t just symbolic; it’s strategic. From here, he coordinates the defense of humanity while grappling with the complexities of Imperial politics and the overbearing influence of the Ecclesiarchy.
That said, Guilliman doesn’t stay confined to the throne room. He has personally led military campaigns, such as the Indomitus Crusade, to reconnect and stabilize Imperium-held worlds. His mobility and ability to inspire troops on the battlefield make him an active participant in shaping the Imperium’s future.
Is Roboute Guilliman any good?
From a lore perspective, Guilliman is nothing short of exceptional. His strategic mind, leadership abilities, and moral compass make him a standout figure in a galaxy plagued by Chaos, corruption, and existential threats. Guilliman isn’t just a warrior; he’s a reformer, constantly striving to fix the Imperium’s flaws while grappling with the overwhelming forces arrayed against him.
On the tabletop, Roboute Guilliman is a powerhouse. In “Guilliman mode,” he serves as a key force multiplier for any Adeptus Astartes army. His ability to buff surrounding units, coupled with his resilience and offensive capabilities, makes him a game-changer in Warhammer 40K battles.
Guilliman’s datasheet highlights his versatility, combining durability, strategic support, and raw damage output. Whether you’re fielding Ultramarines or looking for a powerful centerpiece unit, Guilliman is a standout choice (and fielding a Primarch is just awesome).
In what book does the Emperor talk to Guilliman?
The moment when the Emperor speaks to Roboute Guilliman is a pivotal scene in the novel Dark Imperium by Guy Haley. After his resurrection, Guilliman struggles with the state of the Imperium and the near-worship of the Emperor as a god. Seeking guidance, he approaches the Golden Throne, where the Emperor resides in a state of undeath.
What happens next is both enlightening and haunting. The Emperor communicates with Guilliman, but it’s far from a comforting father-son conversation. Instead, Guilliman perceives the Emperor’s thoughts as cold, distant, and almost alien. This interaction deepens Guilliman’s disillusionment and fuels his drive to act—not because he feels the Emperor’s love but because he understands the crushing weight of his duty to humanity.
This scene in Dark Imperium is one of the most talked-about moments in Guilliman’s modern lore. It reinforces his character as a pragmatic leader struggling to reconcile his past ideals with the harsh realities of the 41st millennium.
Does Roboute Guilliman Have a Girlfriend?
When it comes to personal relationships, Roboute Guilliman’s life isn’t exactly a romantic drama. As a Primarch, Guilliman was engineered for war and leadership, leaving little room for affairs of the heart. There’s no lore suggesting he ever had a girlfriend and given his status as the Lord Commander of the Imperium, romance probably isn’t on his to-do list.
Guilliman’s love, if you could call it that, is dedicated to the Imperium of Man—a relationship that’s equal parts demanding and dysfunctional
Guilliman’s Legacy and Future Prospects
Roboute Guilliman’s return has breathed new life into Warhammer 40k lore and the Adeptus Astartes. His actions as the Lord Commander of the Imperium of Man continue to shape the narrative, offering a glimmer of hope in a galaxy teetering on the brink of collapse.
His challenges are monumental—from internal strife within the Imperium of Man to the unrelenting threats of Chaos and xenos forces. Guilliman’s journey isn’t just about surviving the grim darkness—it’s about redefining what survival means for humanity and changing the Adeptus Astartes forever.
His ongoing leadership ensures that the Imperium of Man remains a force to be reckoned with, even as the universe grows darker with every passing moment. Whether through his military prowess, political acumen, or philosophical struggles, Guilliman remains one of the most compelling characters in the Warhammer 40k universe.
