A large faction of the Pax Imperialis's crew was unhappy with the ship's captain, Master Iphigenia due to his tendency to demand harsh discipline from his crew including frequent humiliations and the stringent punishments for minor slights, as well as habitually placing large numbers of the crew in stasis to cut down on the cost of supplying food, water, and air. During the voyage morale reached an all time low, due to the captains new policy of mandatory flogging the crew to purify them against temptation while the voidship traveled the Warp, despite the fact that Master Iphigenia would never subject himself to the same treatment. Master Iphigenia had years previously been permanently surgically linked to the Pax Imperialis's Machine Spirit with a Mind Impulse Unit and suspended in an amniotic tank . When three popular members of the crew were injured attempting to repair the radiation shielding around the primary Generatorium, rather that allow the injured crewmen to receive Medicae treatment he ordered them each subjected to a total of 29 lashings, resulting in their deaths, and the subsequent mutiny. To put down the mutiny, Master Iphigenia unleashed the ships Murder Servitors, and the crew retaliated but releasing over a thousand of the prisoners hoping that they would serve as a distraction. Instead, members of the 550th Crimson Cavaliers managed to take the bridge, and kill Master Iphigenia. Since the captain was still connected to the voidships' Machine Spirit, his death triggered a system cascade failure, disabling the ships's Voidshields and its Gellar Field, forcing the Navigator to exit the Warp. Even so, daemons followed the vessel into the Materium where they began devouring its crew and prisoners alike in a frenzy of destruction, madness, and terror until their inherent instability caused them to erode. In addition to the damage the vessel suffered from its sudden translation back into the Materium, voidship found its promethium fuel stores dangerously low. The voidship's crew was still reeling from shock of the captain's death, the fear of the punishment they would receive when they reached Xyan if the Imperium learned of their crimes, and now had to deal with the prisoners in their midst, who compelled them to hide in the nearby Gamma Quindecimus system since the binary star system is blanketed in radiation and the dust from a nebula while they made repairs to the ship, and secured promethium from the wells of Rymer. Entering the system, they were spotted by an Adeptus Mechanicus Relay Station which vox-hailed them repeatedly, however the Pax Imperialis ignored the attempts at communication and speed into the nebula hoping its radiation would mask their passage. With their augur array disabled by the radiation, and the solar flares from the binary stars, the Pax had to creep through the system to avoid colliding with the variety of satellites that surround the binary stars before finally reaching Rymer where its gun crew panicked when they detected one of the Adeptus Mechanicus floating cities and opened fire with their Disruptor Macro batteries which managed to shut down much of the Mechanicus tech aboard the floating city.
