The Gatekeeper is a manifestation of heaven where souls go to finally rest in peace, her job is to listen to souls who have died tell their story about how they once lived on Earth and got through life, if she thinks the story is good, she'll let them go to heaven, however if its not good she'll keep them back where they were until their memories are good enough once more, HOWEVER...if the story is good but about a life of crime she'll send the soul to purgatory/hell where they will rot for good
