The Goblin Curse

Publisher's blurb: A goblin in a city street says he's actually human. Who is behind his transformation, and why? And where does the dagger with the strange green pommelstone fit into all this? A noble's devious scheme has gone horribly wrong - a band of heroes must work out wjat is going on before a once-quiet village is devastated. But can they stop the malign influence of the goblin curse affecting them, too? A scenario for 3rd or 4th level characters.
