Worshiped as a god, Uth Katar was an orc warlord in the Black Horde. He led an army into Amn sacking fortresses and cities, gathering exorbitant wealth along the way. Prior to his death he left orders that a tomb should be constructed in his honor and unbeknownst to those who were to build the tomb, he dispatched a cult of assassins to kill them after its completion and to protect its secrets for all time. The tomb has been lost to the centuries, but an unassuming fletcher may have the key to locating it. Your players will clash with orc assassins, the undead and many other surprises.
The adventure includes many opportunities for social encounters as well as two tables of random encounters to be used during travel days and nights encamped.
With little work the adventure can be adapted for any campaign setting. You just need to find a city a few days travel from a mountain range with a river flowing down from it.
This adventure is designed to last 8 to 10 hours and present a fairly difficult challenge to four characters of 5th level but can be modified to suit your needs.
