Heaven (afterlife)

Heaven was a place some humans on Earth believed people went to after they died. The neutron eaters tricked Oliver Harrington into bringing more of them through from their dimension by making him think that angels were returning souls from Heaven to the mortal world. (AUDIO: Lost Souls)
 * Oliver's specific religion or belief system remains unclear.

Iris Wildthyme once spent three weeks in Heaven trying to win back the Ark of the Covenant from the angel Gabriel in a game of gin rummy. (IW: The Unhappy Medium)
