What Is?

[AZOG-THE-GOBLIN]

Whats Mount Gundbad & Angmar of old on the map? Who lives there? In the Hobbbit i'm sure it says somthing about Goblins living there!..but i'm unsure?

[Ailios]

In the Hobbit Gundabad is the capital of the goblins. In a later essay Tolkien says that Mount Gundabad was the place where Durin, the first dwarf, woke up.
Angmar was a realm ruled by the Lord of the Nazgul which was destroyed a thousand years before the events in the Lord of the Rings took place.
