Silver Edge

Founded by Danny 'Edge' Hall after the Cassius School kidnapped his mother and held her at The Center until she died, driving him to burn the school to the ground. The Grand Inquiry established that Cassius policy created Silver Edge, and that the School then used its existence to justify expanding its own power. Silver Edge can shield its people from Cassius magic and from conventional magic generally, and wields an effect that destroys or banishes eidolons outright — rendering summoners near useless against them.
