The Northern Waste was a cold and icy region in the far north end ofMiddle-earth, including the realms of Forochel and Forodwath, located above Mount Gundabad and the Ered Mithrin. It was composed mostly of snow and ice; however it did have several great frozen lakes. Little is known about the area.
The Cold-drakes, which plagued the Dwarves often, came from these realms. It is likely that the "Goblins and Hobgoblins" that later colonized the Ered Mithrin drove most of the Cold Drakes back into the Northern Waste.
