Azog

Azog was a large Orc, both quick and powerful, whose head was sheathed in iron. Nár found that name cut in Dwarf-runes into a forehead, and the Dwarves never forgot it. After a three-year muster, Durin’s Folk and troops from the other Fathers’ Houses wrecked Orc fortresses between Gundabad and the Gladden while searching every mountain den for him. Those who escaped assembled in Moria. In Azanulbizar, also called Nanduhirion, he had held forces inside for a final crisis and later issued from the Gate with his bodyguard when Náin, son of Grór from the Iron Hills, called him out.
