Clairance
Four millions of years ago, before humans even started to be biped. Two Angels of Light, Belfice and Melfice, born from a twin nebula, were sent to the Milky Way to assure their mission. They created a small planetary system composed of a red dwarf and 9 islands. They reunited pieces from a planet that exploded to make the islands and made them orbit around a red dwarf. They each built three islands by themselves, and then, made three other islands together. Belfice made what humans call "Hell" and Melfice what we call "Paradise", they both called those parts by their own name. Inhabitants from Belfice are called "Belficer" and those from Melfice "Melficer". They made an afterlife that looked like humans' fantasy to not stir up their disappointment. But in reality there's no such "good" or bad" only excess. Excess that has consequences. That's why they made 3 islands that are both Melfice and Belfice, to learn the humans that everything is nuanced. The three Melfice's islands are just place for Melficer who are scared of Belficer, those islands have a colder climate. In another hand, the three Melfice's islands are hell being. Only humans who deserve to die are sent there. Because not all Belficers deserve to die. Those islands are covered in puddles of decomposed flesh. The climate is very hot.
when humans die, their souls aren't affected by gravity anymore and fly to the sky. Their souls is then attracted by a space-time rift near earth. Their souls passing in the rift, regenerating all the atoms and their body. They finally arrive to Clairance, Where they become either Belficer or Melficer.
