Antonio
member of a Greek-origin religion/religious order that grew out of a mystery cult to an old spirit who was overtaken and nearly destroyed by the Brothers in one of their campaigns. The god-spirit (maybe Dionysus?) escaped into the labyrinth of incarnation and when his cultus remained and searched for their lost god, they eventually found him again
religion then grew up around protecting spirits working through incarnation and fighting the Mulians and their creations (hence angel-hunting)
there is some dissent within the order as to where to draw the line. Hard-liners will argue against even the Iron-Hearted Woman and say that the Mulians have no right to the labyrinth, but many find it worth making the distinction for some or all of the "sympathetic" or "traitors" - the Lost Sister, Mara, Brigid, possibly Loki, angels who fell in search of wholeness, etc. Each may decide on a case-by-case basis.
Antonio is clearly on the more liberal side; the organization/order/church swings back and forth over time
