The Ilessan Hills (also spelled Ilessen Hills) was a Third Era barony of High Rock, within the Iliac Bay region. This region was bordered by Northmoor and Ykalon to the north, Daenia to the east, Shalgora and Daggerfall to the south, and Glenpoint to the west. The provincial seat was the city of Ilessan Hills. The Haarvenu clan was the predominant vampire bloodline in the region. For hundreds of years, the Ilessan Hills were home to one of the covens of the Glenmoril Wyrd.
