Oon Tien Oon Tien was a planet in the Kathol sector of the Outer Rim Territories , and the homeworld of the Jarell species . Discovered by Galactic Republic colonists roughly 300 years before the Galactic Civil War , the planet was settled by Humans . The native Jarell monarchies traded with the new Human settlers , acquiring weapons and high technology that fueled a change in Jarell society . In the decades preceding the Galactic Civil War , Oon Tien was integrated into the Kathol sector , and became a major manufacturing and agricultural hub . With Oon Tien falling under Imperial rule , Moff Kentor Sarne , governor of the sector , established stardocks in orbit of the planet , resulting in Oon Tien becoming the center of his fleet ' s construction and maintenance operations . Oon Tien remained under Sarne ' s control after the Moff declared himself a warlord following the death of Emperor Palpatine at the Battle of Endor . In 8 ABY , Sarne ' s sector capital , Kal ' Shebbol , fell to the New Republic . As Sarne retreated , he ordered Governor Manon Flint to hold the docks at all costs from New Republic aggression . The planet would prove problematic to the New Republic as it sought to expand its influence throughout the sector . Description . Oon Tien was a planet located in the Oon Tien system in the Kathol sector of the Outer Rim Territories . Oon Tien was connected by hyperspace travel routes to the Torize , Kolatill , and Corjain system s , placing it just off the Trition Trade Route . Torize was fourteen hours travel from Oon Tien , Kolatill was nineteen hours distant , and travel to Corjain took eleven hours . A wet , water - covered , and mountainous planet , Oon Tien was the homeworld of the Jarell species . As the world was integrated into the economy of the Kathol sector , it became a major agricultural and manufacturing center . After coming under Imperial rule , the planet was home to the largest shipyard in the sector as Moff Kentor Sarne — ruler of the Kathol sector both as an Imperial official , and later , as a warlord — had three stardocks established in orbit . As the planet was a major maintenance hub for his fleet , Sarne protected the Oon Tien system with at least two dozen IPV - 1 System Patrol Craft , a full wing of TIE Fighters , and hundreds of proton mine s . History . The native Jarells established a primitive society on the planet based around feudal monarchic city - states , and had developed basic metalworking skills when Galactic Republic colony ships discovered the system around 292 BBY . Human colonists settled on the planet , building several communities and existing side - by - side with the native Jarell city - states . The Jarell monarchs began trading precious gemstones and periods of indentured servitude of their young for weapons and high technology from the Human settlers . The traded equipment assisted the Jarells in a series of internal revolutions that changed Jarell society , although the conflicts never threatened the Human settlements . For several decades before the Battle of Yavin , Oon Tien became more integrated into the Kathol sector , with several large manufacturing complexes being established on the planet . The world also developed an extensive agricultural industry . When Oon Tien came under the control of the Galactic Empire , Moff Kentor Sarne appointed Governor Manon Flint to command the system . Sarne established three orbiting stardocks in the system , each capable of servicing and repairing capital ships up to 300 meters long . The docks were the main maintenance facilities for Sarne ' s forces , and were the largest shipyards in the sector . Oon Tien became part of Sarne ' s holdings when the Moff broke from the Empire in the wake of the Battle of Endor in 4 ABY and declared himself a warlord . Following the fall of the sector capital Kal ' Shebbol to New Republic forces in 8 ABY , Sarne was forced to retreat into the Kathol sector . Sarne ordered Governor Flint to hold the docks at all costs , or destroy them if the New Republic managed to invade the system . As the New Republic spread its influence throughout the sector , Oon Tien would prove to be one of the most troublesome planets as it was too heavily defended by Imperial loyalists to fall easily or quickly . Locations . Oon Tien was home to several settlements of both Jarell and Human origin . The most notable installations on the planet were actually in orbit — the three stardocks that were the hub of the Empire ' s fleet construction and maintenance programs in the sector . Due to the presence of industrial and agricultural based corporations , Oon Tien had extensive manufacturing and farming complexes on the surface . Behind the scenes . Oon Tien was described in " The DarkStryder Campaign " , a supplement for " " by West End Games .
