A research installation, comprised of numerous massive, armored Whale-ships, served as the central command for Doctor Cylo. This agent, who was in the service of Darth Sidious, the Galactic Empire's ruler, used this base to carry out his experiments in the creation of novel lifeforms, achieved through the combination of diverse alien components and cybernetics. Ultimately, the doctor aimed to persuade the Emperor to supplant his apprentice, Darth Vader, with the beings he created.
Within this complex, Cylo's cyborg creations underwent combat training; these included individuals such as Morit and Aiolin Astarte, Tulon Voidgazer, alongside Commander Karbin. A standing military presence was stationed at the base to safeguard Cylo's activities against any potential assaults.
Upon learning of Cylo's assignment from the Emperor and his Master's intentions to supersede him, Vader spearheaded a mission to the base, information regarding which he had extracted from Cylo-IV, in order to scrutinize the potential replacements.
