===Part Two: The Choral City===

Suspicious at the hand-picked nature of the assault force, Tarvitz talks his way into remaining in the fleet when the assault force deploys{{fn|2h}} and investigates the gun decks, where he discovers the ship's crew loading lethal [[virus bombs]] into the ship's guns.{{fn|2i}} Realizing that the marines deployed to the surface are about to be betrayed and wiped out, Tarvitz steals a [[Thunderhawk]] and flies for the surface to warn them. He is pursued by members of his own legion who are part of the betrayal and in desperation puts himself at the mercy of [[Nathaniel Garro]], who is excluded from the assault force and relegated to commanding the frigate ''[[Eisenstein]]'' due to his injuries. Garro, an old friend of Tarvitz's, believes him when he tells him of the imminent betrayal and orders the ''Eisenstein'' to fire on the Thunderhawks pursuing Tarvitz. The resulting cloud of debris hides Tarvitz from the fleet's sensors as he lands on Isstvan, Garro reporting that Tarvitz is dead before preparing to jump to the [[Warp]] and bring warning of Horus's betrayal to the Emperor.{{fn|2j}}
