Caveat Emptor

From publisher blurb: In the outpost of Ob Dakthla, the Heroes meet an Altherian couple that has suffered a great loss and beg for their help. Taking on the Crimson Slavers is one thing, but when their trail leads to the vilest settlement of the Ssethregoran Empire, things go from grim to deadly, very quickly. A 1-round adventure optimized for 6th level characters.
