The Legio Crucis is a Loyalist Titan Legion of the Collegia Titanica, the most powerful arm of the military-minded servants of the Adeptus Mechanicus. Very little is known about this obscure Titan Legion, including even which Forge World it hails from.

The Legio Crucis ' existence in the 41st Millennium has thus far only been verified as one of the constituent units within Battlegroup Geratomro in 398.M41 during the Geratomran Reconquest.

Legion History

Notable Campaigns

Notable Titans

  • Ultimate Sanction - Reaver-class Battle Titan deployed as part of Battlegroup Antares. Operating alongside War's Gift, Ultimate Sanction was the only Battle Titan of the Legio Crucis to be deployed to Geratomro. Hopelessly outgunned by the enemy, Ultimate Sanction nevertheless took to the field, the Imperial Guard hoping that the enemy would take the bait and thus allow a trio of its Shadowswords to ambush and destroy the enemy Titans. Ultimate Sanction duelled and ultimately sacrificed itself to defeat a far heavier Warlord-class Battle Titan which is believed to have been salvaged and reconsecrated by the Adeptus Mechanicus in the aftermath of the Geratomran Reconquest.
  • War's Gift - War's Gift was a Warhound-class Scout Titan. It was the sole survivor of the fighting on Agritha IV and Geratomro.
  • War's Messenger - War's Messenger was a Warhound-class Scout Titan. War's Messenger was destroyed fighting the Drukhari on Agritha IV by a trio of Ravagers.

  • Princeps Yolanedesh (KIA) - Princeps of the Ultimate Sanction and commanding officer of the Legio Crucis' maniple on Geratomro. Slain by an enemy Warlord Titan during the capture of Magor's Seat.
