Zylium 12

Zylium 12 was a type of fuel that could be used to power a class of bomber. The substance required a specific atmospheric pressure to remain liquid; any variation would result in the fuel solidifying.

In 231 BBY, a bomber using the fuel was present on the Outer Rim planet Valo, operated by Nihil marauders. When the Nihil attacked Valo during the Republic Fair, the vessel engaged in a skirmish against Jedi Padawan Ram Jomaram and his companions near the world's communications tower, Crashpoint Tower. Jomaran used the Force to damage the bomber's fuel tank, causing its zylium 12 to instantly solidify and rupture the ship's circuit board, sending the Nihil vessel crashing to the ground.
