The Common Kindreds of the Four Continents

From publisher blurb: Trollworld exists in many different universes. In my universe, there are four continents on Trollworld - the Dragon, Eagle, Kraken and Wolf - and the common, 'good' kindreds have evolved differently on each one. These variations are not so great nad have mirrored the changes in the rule books - the evergreen, ever-popular 5.5, the grroundbreaking 7.5 and the shape of things to come, dT&T.
