Dor Caranthir

Where Mount Rerir, and about it many lesser heights, stood out from the main range of the Ered Lindon westward; and in that angle between Rerir and Ered Lindon there was a lake, shadowed by mountains on all sides save the south. That was Lake Helevorn, deep and dark, and beside it Caranthir had his abode.The northern part of Thargelion (to which it was in origin synonymous), bordering on the inlet of the Belegaer, it contained the last remnants of the old territory of Caranthir in the Elder Days. The western edge of the Ered Luin was cloven by the dry valley of Helevorn, where the old lake Helevorn lay prior to the War of Wrath. The whole was dominated by a part of the tumbled wreck of Rerir. This country was a relic of the Noldorin culture that Feanor's sons had brought to the edges of the leagues of Angbad, but declined after the founding of Ost-in-Edhil. The touchy pride of its two ladies, the daughters of Maglor and Caranthir left it with a fragment of its old glory. Nonetheless it persisted until the mid-Third Age, as severe winters and the slow abandonment of Arda by its people made survival grim. Its mistresses remained afterwards in Forlond, departing with the last ship. Like Galadriel, they saw their time in Endor as gone.
