Ars Magica the Dragon and the Bear (used)

The Dragon and the Bear paints a picture of Russian and Polish history, introduces the pagan priest-wizards known as Volkhvy, delves into Slavic faerie, and explains the Novgorodian Hermetic landscape. Finally it looks ahead to the coming Mongol invasions and presents exciting, tumultuous saga options - even if your saga is set elsewhere in Mythic Europe.
