Kaius Konorius is the new 40k Ultramarines character for 11th who’s a blademaster that trained beside Marneus Calgar and now serves as his champion.
GW just revealed a new Space Marines character, and Kaius Konorius shows up with the kind of backstory most captains would happily steal.
But GW didn’t actually say what he does on the battlefield. Is he just a cool proxy, getting his own rules, or some new kind of character archetype? We’re not sure yet.
Either way, he’s the reward for winning the 11th Edition global campaign, which is where the Siege of Death Mire comes in. Two weeks into the fight, the Imperium is up 2-0 on the Orks, and Kaius is the Marine reward for that win.
If you’ve been following the Warhammer 40k 11th Edition reveals, this is the second Space Marine payoff from Death Mire after the new multi-part Outriders.
Kaius Konorius Reads Like Calgar’s Sword Made Flesh
Updated on September 15th, 2026, by Rob Baer with the release dates and pricing.
- Kaius Konorius Release Date: October 3rd
- Kaius Konorius: a new Ultramarines character, Calgar’s hand-picked champion, wielding a paired set of blades called Severance and Rebuke.
- Why he’s here now: he’s the reward for the Imperium going 2-0 in the Siege of Death Mire campaign.
- Still on the table: two battle zones left to fight over, plus a draw for 40 free 1,000-point armies.

The background lore is what really makes this mini stand out. Kaius trained with Calgar and Cassius as a neophyte, then spent years on Macragge teaching a generation of battle-brothers how to fight with a blade. When Calgar came back wrecked from his duel with Abaddon the Despoiler, he picked his old sparring partner to fight at his side.
The model fits that role too. The armor has clear Victrix Honour Guard energy, and Kaius carries a pair of named blades, Severance and Rebuke, because who wants to go into battle with unnamed swords? This is a duelist sculpt from the ground up, not just another officer with a fancier pose (probably).
The Death Mire Win Is Why Konorius Exists Right Now
Kaius is showing up this week because of the latest campaign results, not because GW randomly picked a Monday to reveal another blue-armored hero. The Siege of Death Mire has players around the world logging games to decide the fate of an Armageddon hive city, with GW putting a new miniature on the line for whichever faction wins each week.
The Imperium won week two, so the Marines get Kaius, and the Orks are now 0-2, and there is only so much hive city left for them to lose.
Final Thoughts on Kaius Konorius Reveal
The new Kaius Konorius model is here, but the datasheet is still missing, and that’s what players probably want to see most for any new model, honestly. A duelist character only works if the rules back up the story, especially with the right statline and detachment support.
