There was a slight logistics mishap and now there's a mysterious alien artifact in storage getting ready to cause an undead shitstorm in the Imperial battlestation. The crew at large is unaware of the Marker and its effects. The Marker is allowed prep time to wreack havoc and mental illness unless / until it's discovered.
R1: Palpatine, Vader, Tarkin, and others among the top brass are not onboard the station at the time.
R2: All officers and crew are on board the station in both the marker's subterfuge and the actual outbreak.
