From the Publisher Blurb:
Deep in the darkest parts of the swamp live a not so quaint race of mushroom folk. Created long ago by a clumsy wizard, the Tvari are ready to spice up your 4th edition Dungeons and Dragons game.
The Tvari are a race of intelligent mushrooms with a great love for the arcane magics that brought them to life. They live for stories of high adventure and are just waiting to explore. Watch out though, this highly competitive race has a natural spore attack that can poison, blind, or even cause an enemy to have hallucinations! Embrace the magic and see what the Tvari are made of. You'll never think of mushrooms the same way again!
