The Story.

The game begins with the discovery of an abandoned battleship seemingly appearing out of nowhere in the Caligari Sector. The leading body of the sector, the Caligari Conclave, makes contact with the titular Inquisitor and requests they investigate the ghost ship. Teleportation is impossible due to a jamming signal emanating from the ship so the Inquisitor boards a transport and heads to the colossus. Upon arrival, the Inquisitor’s transport is shot down by the ghost ship’s automated defenses, which forces the Inquisitor to crash land on the hangar deck. The initial investigation of the ghost ship reveals that it is the Martyr, a Fortress Monastery that disappeared 5,000 years ago and was commanded by Lord Inquisitor Uther Tiberius. Further investigation implies that Uther Tiberius may have been the head of a cult dedicated to the worship of Nurgle, a daemonic entity from the otherworldly dimension known as the Warp. Proceeding deeper into the ship, the Inquisitor comes across an Adeptus Astartes from the Stormwatcher Chapter called Caius Thorn. Thorn informs the Inquisitor that he is led by Lord Inquisitor Klosterheim and that his expedition arrived shortly after the Martyr reappeared; however, the expedition became stranded after the Martyr activated a jamming signal to prevent them from gaining access to the lower decks. After Thorn and the Inquisitor disable the jamming signal, Thorn is seriously hurt in combat and the warp drives on the Martyr suddenly activate. As warp travel could be potentially fatal, the Inquisitor contacts his ship’s captain (Captain Ragna Van Wynter) in order to teleport away with the critically injured Thorn. As the Martyr disappears into the Warp, the Inquisitor pledges to save Thorn in order to learn how to track down the Martyr.
