Dor Daedeloth was the land of Morgoth, lying on either side of the Iron Mountains


Dor Daedeloth lay around Angband, Utumno, Thangorodrim, and the Ered Gorgoroth, and on both sides of the Ered Engrin. It was here that the Orcs and other creatures of Morgoth lived and bred.

After defeating Morgoth's armies in the Dagor-nuin-Giliath, the Ñoldor in the early First Age were halted at Dor Deadeloth in their march after Fëanor, who had pressed on to Angband to face the Dark Lord himself, was mortally wounded by Balrogs.

The Ñoldor then encircled the land (at least in the south), starting the Siege of Angband. They likely built a number of fortresses and outposts there, but these would have been destroyed or claimed in the Dagor Bragollach by the enemy.[2]

The area perished with the rest of Beleriand at the conclusion of the War of Wrath at the end of the First Age.


Dor Daedeloth was Sindarin for 'Land of the Shadow of Horror'.[3][4]
