At one point, a passing comet impacted Needan. The collision sent the planet into a wider orbit on a trajectory rapidly carrying it away from its sun. The consequent, rapid onset of permanently cold and winter-like climate on Needan led to the extinction of the majority of the planet's species.
Geelan scientists eventually began sending out distress signals into outer space. At some point by the time of the Galactic Civil War, the signals were intercepted by a medical starship crewed by members of the Arcona species, who tracked and followed the communication, leading them to Needan. As a result of the following offworlder visit, the Geelan learned of and adapted galactic technology. The fact that their homeworld was dying led many Geelan to emigrate and explore the wider galaxy.
The Needan system was first indirectly mentioned in "Zirtran's Anchor," a roleplaying game article written by Anthony P. Russo and published in the February 1995 fifth issue of West End Games' Star Wars Adventure Journal magazine. The 2009 reference book The Essential Atlas by Daniel Wallace and Jason Fry named the system and placed it in grid square I-20.
