Gunder Ironcrust

Gunder Ironcrust was the son (probably, although there are still no dwarven nouns for females) of Setha Ironcrust, who joined in with a plan of the Deep-Downers to "feel like a real dwarf again" and was left for dead by the Deep Dwarves once they had found the Cube they were looking for in Ankh-Morpork during the events of Thud!. Killed by an axe. His father appealed directly to Sam Vimes for the perpetrators to be found and killed.
