Ohma D'un
Ohma-D'un is one of Naboo's three moons. Following the Battle of Naboo, the Naboo government and the Gungans launched a joint venture to colonize the moon, in an effort to preserve ecological stability, alleviate overcrowding in Otoh Gunga, and foster peace and goodwill. The experiment worked, and created a stable ecology on the moon. Unfortunately, the colony was attacked by the Separatists with a chemical weapon early in the Clone Wars. Many Gungan colonists died due to exposure to an experimental toxin engineered to wipe out the Republic's clone army. The Separatists were then prepared to release the toxin into Naboo's atmosphere, but the plan was foiled due to the efforts of Anakin Skywalker and the ARC trooper Alpha. Naboo's two other moons are called Tasia and Rori.
