Thak was a Mordor Uruk who was the wife of Pugraft and mother of Radbug. During the War of the Ring, she served in Sauron's armies that were invading Gondor. After taking the ruined city of Osgiliath, Thak marched towards Minas Tirith and took part in the early siege to cower her enemies. She entered the city where she openly engaged the defenders of the city, but was slain by Iorlas.
