Gotthilf Puchta

Magister Patriarch Puchta is famous in nearly every College of Magic, as it was he who penned the influential (and enormous) book on magical theory known somewhat misleadingly as A Modest Treatise on the Nature of Magic over one hundred years ago. Copies of this massive tome can be found in most of the Colleges of Magic and even in a few private libraries of Magisters and wealthy nobles. It is not a book of spells but of solid and complex theory, analysing the nature of magic, the Chaos Realm, and other such esoteric and occult matters.

Although not as famous among the public as Magister Luminaries Volans or von Tarnus, in Collegiate circles, Gotthilf Puchta is one of the most respected Magisters to have ever lived.
