In Death's Shadow, the Disciples fight zombies and The Shadow on a ship. The Shadow uses a lodestone in the hold of the ship to create a portal from the demonata universe onto the ship, it also created a bubble of magic around the ship which means that the Demonata can survive there for an indefinite amount of time, the bubble allows Sharmila's legs and Dervish's heart to work while inside the bubble. It is implied that the Demonata released through the tunnel slaughtered all the passengers and staff aboard the ship as there are bodies lying all over the deck and internal rooms.
