Ars Magica ("The Art of Magic") is the award-winning roleplaying game by Jonathan Tweet and Mark Rein-Hagen that focuses on wizards who are as powerful as those we know from legend and literature; in the land of Mythic Europe, those legends are real. The rules encourage players to develop their characters over long periods of time, and make the covenant -- the home base of the characters -- central to the stories. Troupe-style roleplaying allows players to take on the roles of multiple characters, so that the players have equal access to power even though the characters do not.
