Azog/Books

Azog, also called the Defiler, is a minor character in J. R. R. Tolkien's The Hobbit.

Return of the King
Azog killed Thror, who was trying to reclaim Moria from Orcs. He threw Thror's head down to the dwarf king's companion, and warned him that if anyone walked into Moria, He would kill him. Azog later fed the crows Thror's corpse. He also killed Dain's father, Nain. Azog was later killed by Thror's great-nephew, Dain Ironfoot, avenging both Thror's and Nain's death.
