Derenzil civil war

A short-lived civil war occurred on the Wild Space swamp planet Derenzil. Members of the Geonosian species supplied both sides of the conflict with highly specialized, aquatic sonic weapons that were manufactured in a factory near the Stalgasin hive on the planet Geonosis. Due to the risk posed by the project, the factory was equipped with a fighter hangar; however, by 22 BBY, the facility had been abandoned.
