Erech (Dn."Place of Terror") was the Dunael name given to the hill where Isildur Elendilion caused the King of the White Mountains to swear allegiance to him in S.A. 3320. The hill, which lay at the center of the Blackroot vale, acquired its name some years after the Oathbreaking (which took place in S.A. 3434), when the Dead began to haunt the grounds surrounding the Covenant Stone upon which Morthec Gruan's oath had been sworn. Later the Hills name was passed over to the entire surrounding Valley, known therafter as the Vale of Erech. Places of Note:
