The Land of the Sun, or Sun-Lands, is an empty land east of Middle-earth where the sun rises at dawn. Nothing is known of its geography except that there was a curve-shaped mountain range called the Wall of the Sun that corresponds to the Pelóri, the Mountains of Aman.
In the game Middle Earth Role Play by Iron Crown Enterprises, a Sindarin name for the land—Romenor (Easternesse—was given, although it does not appear in any of Tolkien's writings. Using proper grammar in Sindarin, of course, the name would be Romennor, as opposed to the Quenya Rómenórë.
