Mahahaleel, the Territory of the Damned in the Masa'u language, also known as the Land of Spectres, is a timeless island and Kushulainn's Sanctuary. It is considered a "Wati'n" place, or a sacred place, by the Kamijis.
Etymology
Mahahaleel is probably from the Hebrew Mahalalel, great-great-grandson of Adam and pre-Flood patriarch.
