List of Grimoire Cards/The Psion Flayers

""We have just as much to learn from our enemies as we do from our past."

- Master Rahool

Somewhere among their forces, the Cabal hide one of their most powerful weapons, the Psion Flayers. The extent of their ability is still uncharted, but Cryptarch studies and Warlock fears have led the Vanguard to classify them as a serious threat.

Many among the Warlock orders believe the Flayers pulled Phobos from its natural orbit, holding it in place, waiting for the order to release as a weapon."
