The Last King
Mount Gundabad was a mountain at the northern end of the Misty Mountains.
According to the Dwarves, Durin the Deathless, eldest of the Fathers of the Dwarves, awoke at Mount Gundabad in the north of the Misty Mountains shortly after the Awakening of the Elves. Mount Gundabad remained a sacred holy site to the Dwarves ever after and a meeting place with the other Fathers of the Dwarves. However, at some point during the Second Age Orcs attacked the mountain, and took it for themselves.
In the Third Age, the Orcs of Angmar have claimed it as their capital, which remains one of the reasons for the Dwarves’ special hatred of this people.
Early in 1941 TA, a host of orcs from Gundabad descended upon an outpost of Arnor in western Rhudaur, destroying it utterly through sorcerous means. A company of Dúnedain pursued the orc-host north, only to have it melt away into secret tunnels and holes, which are believed to connect in the north to the ancient dwarven stronghold.
Gundabad is a Khuzdul word of unknown meaning. The first element is probably Gund, meaning “excavated tunnel”.
