The Iron Orb of the Duergar
The Northmen and their allies play hardball.
The Northmen are on a rampage, and only the duergar know why. Discover the secret of the iron orb.
In the lands of the Northmen, near the city of Tallborg a mysterious relic was uncovered in a mine: a perfect orb of black iron. The orb was taken to the temple. When Ulvmard, high priest of Odin lifted the orb it revealed its true nature. The orb levitated from his hands, floating before him.
The orb had changed Ulvmard, bestowing him great powers. The orb spoke to him with flattery and advice. As he became reliant on the orb, its power over him extended, bending him to its will and taking control. It used him to further its agenda: destruction of the dwarven race and restoration of the duergar!
Claiming to be acting on Odin's behalf, Ulvmard lead the Northmen to rise up against the dwarves, and ordered raids to pillage the southern kingdoms for the materials he would need to construct a colossal iron warrior to defeat the dwarves.
This adventure has viking and norse mythology influences.
