The world is dying. Guardian Menhirs, great lighted statues that hold back the ever-shifting and dangerous Wyrdness, are going out all over the land, and the greatest heroes of the age have taken it upon themselves to follow the path of King Arthur and find a way to save the world. You are not one of these heroes. Tainted Grail combines survival, exploration, and combat in an extremely player-driven adventure built around Celtic and Arthurian mythology. Build up your character along competing lines of traits, and follow the clues to track down the lost heroes and uncover the fate of Avalon.
