Brok of Gundabad was a son of Skorg. His father led a campaign against Gundabad and eventually succumbed to starvation and death. Brok took up the mantle of leader of the northern orcs and took his father's most prized possessions. It was his father and himself who led the attack against the Dwarves during the Fall of Mount Gundabad and defiled the Dwarves holy site. His actions earned him a deep hatred--and his descendants would come to plague the Dwarves for years to come.
