Editing Mephiston (section)

===The Cybele Incident===
Mephiston was involved in, and helped to resolve, a conflict that nearly tore the Blood Angels Chapter apart. In the novels ''Blood Angels: Deus Encarmine'' and ''Blood Angels: Deus Sanguinius'', a schism occurs within the chapter during a campaign against the forces of [[Chaos]] on Cybele. A young Marine, Arkio, grew wings and then got all uppity and powerful, proclaiming himself to be the reincarnation of [[Sanguinius]], the Blood Angels' late [[Primarch]]. While many of his fellow Marines swore fealty to him, a number of others, including his older brother Rafen (his actual biological brother as well as fellow Blood Angel), refused to acknowledge any truth to his claim. As it turns out, they were right; the whole shebang turned out to be a typically dickish [[Tzeentch|Tzeentchian]] plot intended to tear the Blood Angels apart and turn them to Chaos, and was orchestrated by Inquisitor Remius Stele, a traitor and agent of Chaos.

Eventually, [[Dante|Commander Dante]], who was suspicious of the events on Cybele, sent Mephiston to assess the situation and decide if Arkio really was the reincarnation of Sanguinius. Almost immediately upon arriving, Mephiston sensed the taint of Chaos in Arkio, denounced him as a fraud, and identified Inquisitor Stele as a [[HERESY|heretic]] and a traitor, because Mephiston is a fucking discerning motherfucker and was way too smart for any of those asshats. But Arkio persisted in his claims, and Mephiston, feeling unusually gracious, allowed Rafen to kill him instead of just [[RIP AND TEAR|eviscerating]] the little bastard himself. Still, Mephiston got to annihilate scores of other Chaos Marines and cultists while he was there, so it was a good time overall.
