Sandalphon

The name Sandalphon comes from syn- (“together”) and adelphos (“brother”). During the 12th century, the wizard Arcalaus, nemesis of the knight Amadis, was able to summon Appolyon, Angel of destruction. Overpowered by the mighty demon, the knight asked three mystics—one each from the traditions of Christianity, Judaism, and Islam—to perform a last ditch counter-ritual. Their efforts summoned a mighty protective angel, the Sandalphon, who banished the demon back to Hell. Impressed by the power of their assembled faiths, the mystics decided to create a secret cabal and keep themselves ready to face any mystical existential threat. The group’s descendants have invoked the ritual of the Sandalphon only a half dozen times since, but each was instrumental in defeating an apocalyptic threat.
