Celestia

A main afterlife. Celestia is under Imilios Eidolon's full control. Celestia mainly takes in dead creatures with good alignments. It is a seemingly infintite planet of people living in an ideal afterlife. Eidolon keeps the place locked down most of the time, and the only people that travel there are the souls of the dead. There are living creatures, as humans that lived there millions of years ago evolved into celestials. These celestials are infused with Imilios Eidolon's energy. Humans evolved into beings that are supposedly more akin to Eidolon's form, becoming the natives of Celestia.

The planet itself warps space-time around it, with it seeming to exist in a higher dimension. Travel to this planet means viewing the planet in a three dimensional plane, which can confuse some. This seems to be the reason for the seemingly infinite space inside the planet. Further research is needed into the planet to confirm.
