Allegiance is the fifty-eighth short story published in the The Horus Heresy series that was not originally part of an anthology novel. Allegiance was first published in the limited-edition Sedition's Gate anthology novel.
After the Second Battle of Prospero, the White Scars carry a lone Sorcerer with them -- Revuel Arvida, only survivor of the Wolf King's wrath. Guided by the Stormseer Yesugei, he recovers his esoteric powers, as well as reliving memories of a world turned to ashes. But the sons of Chogoris are wounded too, riven by the treachery that almost destroyed them. As the Khan delivers his painful judgement on those of his warriors who swore the fateful blood oath, Arvida too must decide where his true allegiance lies -- to those who saved him from oblivion, or to the lost legacy of his own Primarch.
