Ileande was one of the nations of the Free Era. It was located in the eastern part of the Westlands. To the north was Rhamdashar, with Hamarea to the northeast, Tova to the south, and Tar Valon to the west. Eventually, this area of land became what is now unclaimed land near Kinslayer's Dagger and Tar Valon.
By FY 963, Ileande had fallen to Hawkwing.
