Moorjhone, the felinoid Moorjhoni's homeworld, existed in the Outer Rim Territories of the galaxy, specifically within the Jospro sector. This planet was situated in a trinary star system, typically illuminated and warmed by two of the three stars at any particular moment. However, once every decade, all three stars would appear on the same side of the planet, causing the event known as the Day of Three Suns.
Rim Commercial Mining operated a mine on this world, led by a Gossam named Ja'Boag. When he arrived, the planet's residents were expelled from their cave dwellings and compelled to reside in the open. This put their lives at risk, since the Day of Three Suns was imminent; without shelter, all life on the surface would be incinerated.
Moorjhone was the location of a battle involving Darth Maul, Savage Opress, and several Jedi who were probing Ja'Boag's link to Maul. Following the conflict, Maul, injured, was found in the desert. He was then persuaded to command a force of these locals against Ja'Boag, enabling their safe return to their homes. Nevertheless, his true objective was simply to eliminate Ja'Boag and free his brother, Opress.
