Apep's sarcophagus was used by Judson to imprison Apep 2000 years ago. The sarcophagus was dug up by archeologists and put on display in a museum where it was opened by a former navy officer who Apep proceeded to possess. The sarcophagus was then taken by Dosa and put in storage until it was opened by Cynthia Rockwell and she was possessed by Apep.
