Ghost Shift
Ghost Shift was the name given to the phase when ghosts appeared.
History
Due to the opening of the Void, ghosts began to appear all around the world. Torchwood One built a machine to turn on and off the ghosts' appearances. The phase when the ghosts were present was given the name Ghost Shift. The public were given set times when the ghosts were going to appear. There were three shifts a day: morning, mid-day and afternoon, with mid-day being the shortest as it only lasting two minutes.
The Ghost Shift was turned on and off using leavers in Torchwood Tower. When active the hole in the Void glowed with a white light. Cybermen over-rided the ghost shift activating it. More ghosts then ever before came through a were revealed to be Cybermen. When the void was closed the ghost shifs ended. (TW: Army of Ghosts)
