It is a wonderful new Ars Magica product in the same vein as Faeries. It gives you an entirely new shamanistic magic system, and allows you to play the shamans of Mythic Europe. Notice the character sketches in the templates: THAT'S what they were supposed to look like in the main rulebook. Anyway, this is a really nifty supplement to have, especially if you're interested in shamanistic folks. It's finished at the printer, so stores should be getting them in one or two weeks.
