Elderly sorcerer, wise but low-born, became Morgar's advisor after Nisur
Ulfdor was of very low birth, and further was a practitioner of sorcery, not a very common dwarvish pursuit, and one regarded with just a little wariness by the average dwarf. His advanced age - Ulfdor was actually old enough to be counted a member of Hildraft's generation - had given him enormous experience and wisdom. No-one was ever going to accept Ulfdor as King; but as an advisor he was going to be very useful.
He died of natural causes in 1618
