Ars Magica: Druesberg
The Emperor Wolf (Silvia of Bjornaer)
Former Druesberg maga, now magical wolf
Local legends speak of the Emperor Wolf, a giant, magical wolf who runs with a pack made up of the leaders of other packs.
The Druesberg magi have encountered the Emperor Wolf, and learned that it is in fact Silvia of Bjornaer, a former maga of the covenant who has departed human society and lives permanently in her heartbeast form. She considers herself ruler of all local wolves.
A feud exists between the Emperor Wolf and the faerie Queen of the Forest.
