A legend was spread through time that the Pandorica, a prison box, contained the most fearful thing in the universe. When the TARDIS exploded it caused the cracks in time many of the Doctor's enemies joined together in an alliance, and it was revealed that they had created the Pandorica to trap the Doctor, as they believed he had created the cracks in time. It was a large greyish cube with time stops and deadlock seals, the ultimate prison. Inside was a chair fit for the Doctor. The Pandorica does not let the occupant escape even through death, and furthermore if a deceased body was placed in it and the living DNA of the same person was collected from another time zone it could bring them back to life. When the universe ended the Pandorica contained a snapshot of the previous universe, so when the light from the Pandorica hit any object it was restored to it's previous state. The Doctor piloted the Pandorica into the exploding TARDIS, sending the light everywhere and resetting the universe.
