Ithor was the fourth planet located in Ottega system of the Mid Rim. It was a planet full of lush life, and the planet's surface had not a touch of civilization on it. The Ithorians themselves, otherwise known as "Hammerheads," built great floating cities that did not harm the surface, which they considered to be sacred. Entry upon the surface was forbidden, unless one stayed there permanently. Some Ithorians such as the Oracle were compelled to go down to the planet surface, however, as they "heard the call" of Mother Jungle, the Ithorian religion's personification of Ithor's world-spanning jungle. The surface of the planet of Ithor played host to numerous plants, including the bafforr tree, which possessed telepathic capabilities. The planet contained andurite stone, and every three Ithorian years was the center of the Time of Meeting. The planet had many moons in its night sky.
