The Medieval Bestiary is an Ars Magica supplement for storyguide and player alike. The creatures are presented from a more medieval perspective and blended with game statistics to help to set the mood for your saga. The creatures described within this tome are known to the people of Mythic Europe, the setting of Ars Magica. Thus, there are well-know, common animals - horses and hounds, cats and cows - and other, more exotic beasts - dragons, gryphons, and sirens. Mundane and magical beasts, each presented with a description written by Caprea of House Bjornaer, which reflect her views as a maga and scholar in the Order of Hermes.
