A significant Imperial naval base, sometimes called an Imperial outpost, existed on Jahnae which is located on the Inner Rim Territories planet Bestine IV. The Empire built this facility, which functioned as a shipyard, to suppress rebel activity in the Inner Rim after the Separatist Alliance was very active there during the Clone Wars. Speculation suggested it served as a research and development center for creating weapons. The base's presence caused numerous inhabitants, including the independent trader and future rebel pilot Jek Porkins, to leave Bestine IV.
Between 3 ABY and 4 ABY, the criminal organization Crimson Dawn discovered that the outpost was struggling to maintain order among the local population. According to Margo, the people did not want the Galactic Empire there. Subsequently, Margo offered a job to T'onga, a bounty hunter who needed credits for her crew. The job was to intercept an Imperial shipment of munitions headed to the base, which were intended to suppress a local insurrection. The hope was that this would disrupt the precarious balance between the Empire and the people of Bestine. The base was obliterated when the transport was directed toward it at maximum velocity, after T'onga's crew, aided by Beilert Valance, who had rogue from the Empire, overcame the Imperial forces guarding the transport.
