A One−Round D&D LIVING GREYHAWK®
Iuz Borderlands Meta−Regional Adventure
Version 1.0

For over a century, the proud Wolf Nomads have been denied access to their sacred ancestral burial site located in the Howling Hills – a place now under the control of Iuz The Evil. A nomad foray during the 580’s had early success but eventual failure, and it seems the only way to retake the Wegwiur Thralls is to have a group of cunning adventurers infiltrate the tomb, and secure it from the inside. But who would be mad enough to undertake such a mission? A Living Greyhawk adventure for characters ranging from levels 3 to 13.
