Gandalug

Gandalug is the founder of the Shield Dwarf stronghold of Mithral Hall. He was captured by the Matron of House Baenre and imprisoned in a magical ring many centuries ago before being released by the Time of Troubles. Bruenor Battlehammer abdicated his reign to allow him to become King again. The years of abuse and psychological damage seemed to have lead him to a premature but peaceful death.
