Somewhere in the depths of the former dwarven city of Tar-Borak, between the old mines and the goblin-occupied amphitheater caves, you may have the misfortune to meet the creature the orcs call Ulug.
Some say he is a fallen demon lord or dark godling, although nobody knows for sure. What all agree on is what happens when you meet Ulug: he demands whatever you have that is most precious.
Some have given him all their possessions, or just a favorite weapon or a family heirloom. Others have given him a sibling or a loved one. A few brave warriors have chosen to fight; those found out Ulug was easy to kill. They then went mad with pain and died in a few days.
And meanwhile Ulug kept coming back.
