Pabu island, often shortened to just Pabu, was a secluded island situated on the tropical planet of Pabu. The island was governed by its mayor, Shep Hazard, and its population largely consisted of refugees who had fled the Clone Wars. Despite its limited resources, Pabu offered a welcoming environment for refugees, notably free from the influence of the Galactic Empire. According to Phee Genoa, it was her "home away from home."
Sea surges occasionally impacted the island. Consequently, a substantial wall was constructed around Upper Pabu as a protective measure. Over subsequent years, Pabu expanded to include Lower Pabu due to an increase in the number of inhabitants.
The Archium was located in Upper Pabu. It served as a repository for recovered artifacts from across the galaxy. The Archium also housed the early warning system, which was used to alert the inhabitants when a sea surge was imminent. A large landing pad was positioned just outside the Archium, at the island's highest point.
By approximately 18 BBY, a significant sea surge had not occurred for nearly three decades. However, in that year, the island was struck by a series of tremors, which triggered a major surge. Lower Pabu sustained considerable damage from the surge; however, with the assistance of Clone Force 99, all residents were able to evacuate to the safety of Upper Pabu.
Despite its remote location, Clone Force 99's presence on Pabu was discovered on several occasions. The Force-Sensitive Outcast Asajj Ventress located them there, seeking to evaluate Omega's aptitude for connecting with the Force. Later, the clone assassin CX-2 tracked the clones to Pabu after obtaining data from Genoa's starship, the Providence, and destroyed their vessel, the Marauder. Soon after, an Imperial division arrived with the objective of capturing Omega, and, after causing widespread destruction to parts of the island's community, they succeeded in capturing the young clone before departing.
