The Crooked King's Cup

From the introduction: Do you dare seek out the Cup of the Crooked King, and risk eternal damnation for the chance of more riches than the King of Salamonis himself has ever seen? Of course, I know what your answer will be. This is The Crooked King's Cup, an Advanced Fighting Fantasy 2nd Edition adventure for an experienced adventuring party, although it will be easy enough to adjust the statistics of the foes and dangers to suit any level of skill.
