Oluna Biqua was a floating city on the gas planet Genarius. It was well known as a place to go for luxury holidays.
During the Clone Wars, the Metatheran Cartel freighter Porthoy landed in the city, and the gas Trinex-M was released after an accident. It entered the city's air-circulation system and infected most of the population, giving them Force powers and driving them insane. However, the Heroes of Cularin gained a sample of the gas; this was used to create a cure for it, which was given to the population.
