Hayman

 was a member an old Earth species, 50 billion years before humanity evolved, hidden behind the door.

His species made an experimental time travel experiment which obliterated them as a species and flung them to 'Time's End', the very end point of all of time and space where the laws of all physics broke, where they became god like. Trapped in an eternity of meaninglessness nothing, every single potential species that was produced on Earth that could have become dominant and tried to venture further than the solar system were forcibly sucked into the omniprescent door and grounded down into a mass of screaming, crushed creatures. They did this as a result of their immense rage and bitterness of their failed experiment and their imprisonment at the end of time. (AUDIO: The Nowhere Place)
