Realms of Afterlife:
When someone dies in Ethri'il they immediately appear in a line before a massive gate with glowing arcane runes upon it. People within the line are encouraged to walk single file through the gate one at a time. The gate judges the souls that walk through it.
This Gate, then sends the souls to one of 4 realms.
Limbo & Testing : This realm consists of four domains. Meant to be a test of character--to weed those who deserve a peaceful after life from those who do not deserve such. It is also a catch all place for when the gate is overwhelmed with more than one soul passing through it. The Domains are as follows, The Wastes (Desert/Wasteland), Land of the Wayward (Swamp/Jungle/Wetlands), The Frigid Climb (Mountainous/Artic land scape), The Endless Sea (Sea/Ocean area with a few desert islands with very little upon them).
Realm of Plenty: This is where all good endings take place, each pantheon has a domain within this realm--but no one realm is fully cut off from another. For why should the good be forced to never see their beloved friends and family if they should aspire to a different pantheon?
Realm of Endless Torment: This is where all souls who cannot be redeemed suffer for eternity. If a soul can be redeemed they serve a sentence and then are sent to the Limbos as a test to see if they can find their way--and to see if they truly learned their lesson.
New Lands of Rebirth: New to the world are the dual domains of rebirth. Filnar and Raenisa share the domains of Rebirth where souls can now choose to be reborn after a period of time.
It is said that souls that have yet to pass the Gate are far easier to bring back, and those who have passed the Gate--are much more difficult to retrieve.
While in the limbo realms--Spirits can indeed feel hot/cold, all emotions and some new ones, they can feel hungry and tired... they feel everything as its meant to mimic the mortal realms.
