Hulgrof was one of the most illustrious dwarf kings of the north. He was a real thorn in King Skutagaard's side during his lifetime. Hulgrof and his fleet of Drakkar were sunk during an assault on one of the king's islands by catapults, in the battle of the Holy Triad against the evil monarch.
Centuries later, The Lich Lord Skutagaard needed a mighty warrior to conquer the throne of the dwarves, and the sunken body of Hulgrof was the perfect vessel: as a punishment and to emphasis his hatred for dwarves, King Skutagaard cursed the remains of Hulgrof bounding it with the souls of his dwarf comrades.
Hulgrof became a giant abomination, driven by the regrets and hatred of the dwarven souls that made him up. Hungry and insatiable he hunts his favorite prey, the dwarven people of Skutagaard. Over time he and his war-band of Draugr has become a plague and a great dishonor to the dwarf people.
