Space is not really a part of my version of Hell and Heaven. Heaven has the angels of all the ranks. And its own version of "God". The Human World is well Earth. And Hell is a realm that's accesed if you die or find a portal. Hell has The 7 Rings which is based on "The 7 Deadly Sins". There are also ringleaders of the the rings being the personification of the sin they live in.
