Meet the sinister Dark Mechanicum in Legions Imperialis with terrifying new units like the Silica Mutus, Stalker Constructs, and the deadly Harpax Swarmers!
Unleash the Dark Mechanicum: New Legions Imperialis Units Revealed

If you’ve ever wondered what happens when you mix a thirst for forbidden knowledge with a pact to ruin the galaxy, look no further than these new miniatures and constructs, which are not only spiked, spidery, and lethal but also packed with enough lore to make any warlord salivate.
Silica Mutus: When Machines Think (And Plot)
The standard battle-automata of the Mechanicum are impressive, but the Dark Mechanicum doesn’t settle for “standard.” Enter the Silica Mutus—these are machines with more than just a basic subroutine. Each construct has its own rudimentary intelligence, often described as animalistic when it roams solo, like a hungry predator. But put them together, and things get wild.
In packs, these machines form a gestalt intelligence, learning and adapting as they fight. If you’re picturing a horde of robotic wolves that not only follow orders but also figure out new ways to tear your enemies apart, you’re on the right track. These bad boys are not bound by the same shackles as their loyalist counterparts, and they aren’t afraid to think outside the box… or, in this case, outside the forge.
Stalker Constructs: Hunters with a Nasty Edge

These constructs may share a similar build, but don’t be fooled—they’ve got very different jobs on the battlefield. The Tennebrax “Archers” are your long-range executioners, softening up enemy lines with storm laser flensers. Think of them as the meticulous snipers of the Dark Mechanicum, calculating their targets with ruthless precision. But once the lines are softened, the Errax “Butchers” are in charge, who do exactly what their name suggests: close combat slaughter.
And here’s the kicker—they work best when they’re together. The Archers set ‘em up, the Butchers knock ‘em down, and somewhere, a Dark Magos is watching the carnage with something that vaguely resembles a smile.
Harpax Swarmers: Chaff with a Nasty Bite

A Stalker Constructs box packs in 30 models, including eight Harpax ‘Swarmer’ Scout Hosts, along with two of each Errax, Tenebrax, and Scintillax for variety. Meanwhile, the Serperos ‘Overlord’ Heavy Stalkers box comes with four hulking models. And here’s the kicker—both sets also come with the necessary terminals to field Errax, Tenebrax, Scintillax, and Serperos in Adeptus Titanicus.
Sure, they’re chaff—but in the world of the Dark Mechanicum, chaff can still tear you apart before you blink.
Scintillax ‘Cyclops’: The Ultimate Puppet Master

Under its control, formations of Stalkers and Swarmers become even more efficient, which is saying something when your battle automata already have a reputation for ruthless precision. The Scintillax essentially turns chaos into coordinated destruction.
The Doom of Magma City and the Dark Mechanicum’s Rise

So, gather your spike-clad, red-eyed monstrosities and prepare to wreak havoc. The Dark Mechanicum’s time has arrived in Legion Imperialis, and it’s not here to play nice.
