Primordial - P

Petitioner = Petitioners are a special class of Adepts who may or may not develop supernatural traits from Degree progression, but instead from the interaction with a specific type of Supernatural. Priests develope supernatural abilities from the Saints they venerate, Archangels receive them as gifts from Celestial Patrons, etc. 
Primordials = The term 'Primordial' is applied to alien beings believed by most Adepts to predate our own universe. They are strange creatures that may or may not be material in the same sense as ourselves. The Order of Gnostics knows the Primordials best.
Psychic Powers = The Primordials are vastly psychic beings whose powers of the mind can only be described as alien. This combined with their ancient level of Forbidden Knowledge means that Gnostics (or anyone who deals with Primordials) will often have their minds tested for it. See the Drain for more info on the side-effects of dealing with Primordials.
