Bruk was a large Goblin who was one of his kin's best warriors during the takeover of Moria. He was known to count his kills and would continue if he ever finds one that would challenge him. At some point when the Fellowship of the Ring entered Moria, Bruk was part of Horvak's regiment that tracked the company to Lothlorien, homeland of the Silvan Elves. It was there that Bruk met his fate by a group of Elves that were guarding the borders and was shot him.
