From the back cover:
Someone or something is killing the Othlorx ("the Uninvolved") dragons of Taladas. Not only good dragons, but the evil ones as well. Who or what would be so angered at these dragons as to slaughter them indiscriminately? To find out, the PCs must masquerade as dragon hunters and set out to destroy dragons. It's a dangerous game - if the dragons don't get you, your eployer's might!
This quest will take the heroes from the alleys of rundown Gridmire through the entire Southern Steamwall region of Taladas and eventually to the Astral plane. The poisonous vapors of the Indanalis Sea have wreaked havoc with the inhabitants of this region, so be prepared to meet anything!
This AD&D adventure, set in the world of the DRAGONLANCE saga, is the second of an epic trilogy that begins in the previously unknown continent of Taladas and ranges out to the Astral plane. The players assume the roles of dragon hunters to discover the identity of the "master" behind the plane to wipe out the Othlorx dragons of Taladas.
