Fel became a thorn in Krayt ' s side , leading guerrilla attacks , similar to what the Rebellion had done almost 150 years ago . Fel could not lead a proper offensive without a major base , so he moved to take Bastion , the former capital of the Imperial Remnant , the government that preceded Fel ' s Empire . Changing loyalties . Emperor Roan Fel arrived at the planet aboard a " Nune " - class Imperial Shuttle , escorted by three of his Imperial Knight s , Masters Antares Draco , Ganner Krieg , and Sigel Dare . He was received by Lieutenant Kiefer of the Imperial Army , who ordered him to surrender . However , Fel gave an impassioned speech to the Imperial stormtroopers of the 501st Legion , calling upon them to join him in the fight against the usurper Dark Lord of the Sith . The 501st immediately knelt before their rightful Emperor , thus leaving the service of Krayt ' s Empire . Lieutenant Kiefer ordered the stormtroopers to stand , stating that they owed no loyalty to the deposed Emperor . When none of them obeyed him , Kiefer drew his blaster on Fel , intending to execute him .
