The Medieval Bestiary Revised Edition
This Ars Magica supplement presents animals and fantastic beasts as they are understood in medieval Europe, combining encyclopedia-like descriptions with Christian moral interpretations. It covers familiar creatures such as horses, hounds, cats, and cows alongside exotic beings including dragons, gryphons, and sirens. Each creature includes a description from a Bjornaer scholar, with game statistics where appropriate for Ars Magica Fourth Edition. The material supports stories about familiars, shape-shifting Bjornaer characters, and encounters with animals and magical beasts.
