The Iron Mountains (S."Ered Engrin" or "Orodengri"; Av."Rô-angâi", La."Raudënymânyënyët") were the titanic northern barrier of Middle-earth, forged in the Elder Days by Melkor as an impregnable barrier against the Valar. Stretching from Utumno in the east to the Angband in the west, these mountains were a land of blackened peaks, jagged ridges, and endless glaciers, their heights crowned with perpetual storms and choking fumes from Morgoth’s forges. Their iron-hard slopes were riddled with deep tunnels and vast pits of fire, where Things of Morgoth, Trolls, and legions of Orcs were bred in darkness.
The Thangorodrim, Morgoth’s dread stronghold, loomed at their southwestern edge, casting its malignant shadow over Beleriand. After the War of Wrath, much of Ered Engrin was shattered and drowned, but in the east, remnants of their horror endured, shaping the blackened and broken lands of Forodwaith and the icy wastes beyond the knowledge of later ages. Ever since that cataclysm, its westernmost portion lay mostly beneath the sea, while the rest of the range was sundered by the great Bay of Utûm.
