The comic that came before the RPG. The first 200 or so pages are comic content of various artists, but all in the WitchGirls School and world. The next dozen or so pages is the Coventry School written up for the Witch Girls RPG. And we end with WGA write-ups for all the characters that appeared in the comics.
One of the great things about the Witch Girls game are the characters. So this is a nice treat really.
If you are a fan of the game and want some more NPCs for your own school or need some ideas on adventure then this is a great book to have.
