The Terax Nebula was a large Nebula near Muunilinst. It was known for its large quantities of Tibanna gas, but extracting the gas was risky due to energy storms in the nebula. Around 5 BBY, a battle took place there between Imperial and Rebel forces, although unbeknownst to them they had been manipulated by Unit 8311, head of the Steel Legion. After the battle, the Legion set up secret tibanna extraction stations in the nebula, and sold their output on the black market.
Club StarDust was also located very close to the nebula, and provided specutacular views of it.
