Erôn-Henath; meaning "castle on the hilltop" in elvish, is a large fortress located in northern Eldara at the southern base of the Forlorn Mountains.

This castle was built in the Fourth Age by the kingdom of Eldara, and today guards the border region between Eldara and Melinarë, which have long been plagued with scattered raids by orcs coming down out of the Forlorn Mountains.
