A member of the volamtar, the clergy of the dwarven deity and patron of travelers Marthammor Duin, Thorgrun of Clan Watchever has wandered the Sword Coast for many years. Recently, he has started working with volamtar clerics in Waterdeep to establish a permanent city shrine to Marthammor Duin, often adventuring to help raise necessary funding.
