Generation Ship Thetis is located in Nefertem, orbiting the planet Nefertem 6 A.

Shortly into the Thetis’s ninth generation, passengers began reporting whispering sounds coming from comms units. The sounds, a digital signal being picked up by the ship’s comms array, drove passengers homicidally insane, resulting in the loss of whole decks.

The signal was found to have originated from an uninhabited planet that the Thetis had passed 15 lightyears earlier. A crew member who accidentally heard the signal described it as a whisper that said “kill them all”.

The final log is a garbled transmission of the signal.
