Dor Daedeloth was one of the three large regions of western Middle-earth, along with Beleriand and Hithlum. It lay all around the fortress of Angband and on both sides of the Ered Engrin. Its borders were the Ered Wethrin to the west, the Ered Luin to the east, and the Dorthonion, the Pass of Sirion and the March of Maedhros to the south.
The Ered Engrin, an absolutely unclimbable chain, split the region in two separate parts. The southern part was Ard-galen, the great grassy plain north of Beleriand, later to become the desert of Anfauglith after the Dagor Bragollach had utterly burned it. The northern part was an unnamed region, cold and vast.
