A One-Round Living Greyhawk Principality of Ulek Regional Adventure
From the introduction:
Royal Army and Mine Ranger members sent on a mission to explore caverns somewhere within the Lortmil Hills have not returned. You are asked to find them and bring them home safely but this is easier said than done. A slumbering evil has awoken and it hungers once more. Will a tragic choice from the past doom the lives of the innocent, delivering a sacred and powerful relic into the clutches of the Principality of Uleks greatest enemy or will heroes rise in time to stop it?
A Principality of Ulek regional adventure for APLs 2-12, and Part 2 of the Gems of Ulaa Series.
