A Diceless adaptation of Ars Magica - (no experience necessary) - (Borrowing from one of Eric Todd's experiments)
You are part of a magical community, set in Scotland, 1220 A.D. Reality functions just like the superstitious peasantry of that time/place think.
Magic is evil - probably satanic. So you hide what you can do from the world.
The world, magic and mundane, has something to say about this!
Experimental system; easy to learn world, provocative role playing opportunities.
You will be asked to play multiple characters in the course of the game.
