Emperor ' s Observatory The Emperor ' s Observatory on the planet Pillio was one of several observatories maintained by Emperor Palpatine throughout the galaxy , each one being part of his goal to find out what laid beyond the known galaxy . The Pillio observatory contained a number of artifacts from the Emperor ' s collection . In 4 ABY , after the Emperor ' s death , the Emperor ' s Observatory was discovered by Jedi Knight Luke Skywalker and Imperial Agent Del Meeko of Inferno Squad . Meeko ' s orders were to destroy the observatory , but Skywalker convinced him not to and to avoid inflicting damage to the planet . Skywalker left the Observatory with a compass , an artifact he sensed was important . Description . The Emperor ' s Observatory was a bunker on the planet Pillio . It was one of many observatories that Emperor Palpatine , also the Dark Lord of the Sith , established across the galaxy . Each observatory looked beyond the galactic rim with the intent of finding what laid beyond the known galaxy , and each had a specific purpose . The Pillio observatory contained a number of items the Emperor had collected before his death , such as a compass . The bunker had no locking or unlocking mechanism , and it could only be opened with the Force . History . During the Clone Wars , while he was still Supreme Chancellor of the Galactic Republic , Sheev Palpatine felt the call of unknown space from beyond the galactic rim . He wanted to explore the Unknown Regions and galaxies that laid beyond his own , and even theorized that such unexplored space could be the source of his dark side powers . He built observatories , such as the one on Pillio , as part of that exploration and used this one to store several artifacts . In 4 ABY , Palpatine — ruler of the Galactic Empire — was killed during the Battle of Endor . After the battle , Inferno Squad member Del Meeko was tasked with leading a contingent of Imperial trooper s to Pillio in order to destroy the Observatory . At the same time , Jedi Knight Luke Skywalker also traveled to Pillio . He felt called to Pillio by the Force , and the arrival of Imperial troops confirmed his suspicions that there was something special on the planet . After Skywalker destroyed the Imperial forces he encountered and saved Meeko , who was trapped after an encounter with scritter s who lived in Pillio , the two worked together to find the Emperor ' s Observatory ; neither felt the other was truly their enemy . The Jedi opened the door with the Force when they arrived , and Meeko realized that the Emperor — the man who destroyed the Jedi Order — could also use the powers of the Force . Once inside , Meeko felt that none of the items were of any value or worth the Emperor protecting , but Skywalker discovered the Emperor ' s compass . Meeko allowed him to keep it , and Skywalker convinced Meeko not to destroy the Observatory . The Empire , Skywalker said , had already inflicted enough damage on innocent worlds . Behind the scenes . The Emperor ' s Observatory on Pillio was introduced in a mission during the single player campaign of " Star Wars Battlefront II " . Observatories and their connection to unknown space were previously introduced in " " .
