The Dark Arts

From the introduction: This supplement to Advent will introduce new rules and expand on the ones already found in the core rule book. None of these rules should be used with out the approval of your Storyteller before you begin playing with them.

"This supplement is aimed for games which will involve PCs or NPCs using unsavoury means to their goals or training Dark Odic monsters. You will not find anything useful for character's of pure heart, unless you wish to know your enemy."
