Warhammer 40,000

As word of Horus's treachery spreads to fully half of the Legiones Astartes, Terra looks to the remaining loyalist Space Marines to defend the Imperium. One group, however, remains curiously silent in spite of apparent efforts from both sides to contact them the noble V Legion, Jaghatai Khan's fearsome White Scars. In the ork-held territory of Chondax, a bitter war has been raging since the Triumph at Ullanor, and only now do the sons of Chogoris return their gaze to the heavens... This story is also in Legacies of Betrayal, book XXXI of the Horus Heresy series.
