Ened: was a small island that lay straight out from the Firth of Drengist, southwest of Lammoth and northwest of Nevrast. The island was roughly four times longer than it was wide, and its long axis lined up with the Firth. There is no mention of the island in the annals of the First Age so it may have been uninhabited.
The Mod: Due to the fact that this island was uninhabited, it may still exist within the Third Age. Even if it is added as an island smaller than Tol Himring, it is still an island that is part of Tolkien’s universe even if this is the only mention of it. There doesn’t even need to be a faction on it. It should just simply exist as an uninhabited island.
