Changes

As the level of treachery within [[Horus]] and Fulgrim became apparent Tarvitz placed himself in the line of fire by willingly going to [[Isstvan III]]. There he and all suspected loyalist members would be betrayed by Horus. Horus ordered the bombardment of the planet, but Tarvitz, along with [[Garviel Loken]] and [[Tarik Torgaddon]] of the Luna Wolves, managed to turn the loyalist survivors into a cohesive fighting force. This "line officer" turned a planned slaughter into a full-scale battle, confounding the great [[Primarch]]s themselves. At the climax of the battle, Tarvitz fought [[Lucius (Emperor's Children)|Lucius]] in single combat after the swordsman had betrayed his own comrades. Tarvitz emerged as the victor in the duel, but Lucius managed to escape. Ultimately Tarvitz's true fate is unknown, but this true child of the Emperor he seems to have met his fate on Isstvan III.
