Varnarites

(Ordo Sancti Varnari).  This group of Deryni adepts and scholars split from the more conservative Gabrilites about the year 745, taking with them their library and records to new quarters in another part of the city of Grecotha.  There they established the Varnarite University or schola, where they trained would-be Healers, although their approach to the subject tended to be somewhat pragmatic when compared to the philosophical teachings of the Gabrilites, and often ignored the more subtle nuances of the art.  The lectures of Jodotha indicated that certain records of the Varnarites had been placed in a secret archive before the school moved to its new quarters in Grecotha.
