You are enjoying a quiet tankard of ale in the Main Hall when you notice that it is getting dark outside. This normally wouldn't bother anyone but it's only 9 o'clock in the morning. You can hear the cries of a large crowd forming in the square. As you leave the hall to investigate, you see the reason for the consternation. A large black cloud has formed over the town and is sending down jagged bolts of lightning. The frequent flashes show the cloud to be shaped like a giant taloned hand. The crowd surges to the massive temple dominating the end of the square, where they mill about and implore the priests to come forth and repel the evil manifestation.

Just as the crowd is reaching a fever pitch, the bronze doors of the temple swing open and Pindar Rambis, the high priest, appears. His voice rings out over the crowd:

"Be afraid, people of Eamon, for the conflict between good and evil is at hand and the evil ones have found new strength. My commune with the spirits has revealed that the tomb of beloved Anharos has been desecrated by grave-robbers. His Diamond of Purity has been stolen! Anharos will reveal the gem when he is made whole again. Woe unto us if his tomb be not restored."

The name of Anharos is known to you. He was an ancient king of Eamon renowned as a good and just man. During his reign the legions of evil were beaten back to the wilderness areas of Eamon and good men prospered. The source of his great power was his Diamond of Purity, a gem of wondrous beauty and infinite value. Legends say that the gem was a gift of the greater god, Alaxar, god of the sun. The gem was entombed with Anharos when he died so that his power could continue to strike at evil from the spirit world. His tomb is a great pyramid lost in the trackless wastes of the Desert of Terza, the Desert of Endless Sorrows.

Anyone who could restore the tomb would be deemed the savior of Eamon and amply rewarded. It is the ideal quest for an adventurer of your ilk: big dangers — big treasures.

Good luck, and may Alaxar light your way.
