From the back cover:
After arriving at the seemingly abandoned trading post of Garland's Fork, the heroes discover to their horror that all of the inhabitants have been transformed into black trees! Upon further investigation, they find clues that lead them to the hidden lair of Nockmort, a treant corrupted to unspeakable evil. Nockmort has been transformed by the strange radiation of a recently discovered meteorite that has fallen from the heavens. The once benign tree folk is now twisted and evil, a diabolical force to be reckoned with! In order to save the town of Garland's Fork, the heroes must enter his sunless garden and do battle with other mutant creatures. And, along the way, they might just discover fabulous treasure...
