Kakan, a Mustafarian child residing during the dawn of the Imperial Era, held a deep captivation for the Jedi. Upon learning of a supposed Jedi Knight's arrival on Mustafar, he ventured alone towards the lava mine, the location of the reported sighting. Unbeknownst to Kakan, the individual in question was actually Anakin Skywalker, newly consumed by the dark side of the Force and transformed into the Sith Lord Darth Vader. Vader's mission on Mustafar was to kill the Separatist Council under the command of his Sith Master, Darth Sidious, who was simultaneously declaring the establishment of the Galactic Empire on Coruscant. Kakan discerned that the visitor was not a Jedi when he observed Vader's yellow eyes. Overcome with fear, he ran as Vader gave chase, intending to eliminate any witnesses. A miner named Lellis saw the pursuit and rescued Kakan by disabling the repulsor vents, causing psychoactive fumes to fill the area and allowing them to escape. However, the fumes affected Kakan, causing him to hallucinate a vision of Vader falling from a ladder he was trying to ascend.
