As the Siege of Terra rages, a group of Loyalist Titans attempt to hunt down and eliminate the Arch-Traitor, the Warmaster Horus, in the first episode of this new three-part original Warhammer animation.

Princeps Gemnon and Aurora Ferrum take a gamble on glory – but will unforeseen resistance put an early end to their mission?

Keeso and Gemnon lead the charge on the traitorous Warmaster's position. The risk is great, but the reward could mean salvation for the Emperor's forces – if all is as it seems.
