Moria (Sindarin for "Black Chasm") was the name given by the Eldar to an enormous underground complex in north-western Middle-earth, comprising a vast network of tunnels, chambers, mines and huge halls or 'mansions', that ran under and ultimately through the Misty Mountains. for many thousands of years, it remained a centre of dwarven industry was also called Hadhodrond by the Sindar, but the Dwarves dug too greedily, and awakened a terrible power: a Balrog. It slew many, helpless before its power, the Dwarves fled in terror. Moria is now occupied by a host of Goblins.
Mount Gundabad is an orc-infested mountain at the northern end of the Misty Mountains. It was from here that the gargantuan Goblin-horde present during the Battle of the Five Armies attacked and marched from. Their leader, Bolg, son of Azog, was the supreme commander of the Orcs from Gundabad and presumably the northern Misty Mountains. This may have been one of the many breeding areas of the dreaded Wargs that were so feared by the Free Peoples.
