The Loc'na ko is a group of planets whose resources were depleted by mining. According to Jaffa legend, Osiris hid on a planet of the Loc'na ko, a legend which closely parallels the Earth mythology of Kheb. By comparing the databases for the Abydos cartouche and the map of the Ancients, SG-1 was able to locate Kheb as a planet within the Loc'na ko.
