Entooine, a moon that was tidally locked to its gas giant parent planet, existed within the Entoo system. This system was located in the Outer Rim Territories. As the sole inhabited world in its system, Entooine possessed an incredibly strong electromagnetic field. This moon was an icy and cold place, characterized by icy fissures, polar ice caves, lichen, shrubbery, native quohr, and two intelligent species: the Askhew who lived in tribal societies, and the blue banthas.
This planet became a member of the Alliance to Restore the Republic. It was used as a Rebel strike base due to its strategic proximity to an Imperial trade route.
