Ars Magica is a "role playing game aboutsorcerers and their allies in  Mythic Europe." Play focuses around the covenant, a community of magi,  companions, and servants and guards (known as grogs). Players take up  multiple roles in the game, playing as all three types of characters  throughout a campaign.  A highly influential game that launched the  careers of many well-known designers, we focus primarily on the current  edition, fifth, but also talk about earlier ones.
