Third Realm

Third Realm – This is the frozen underworld where individuals go to spend their afterlife upon death, either before they reincarnate or if they don't at all. The "third realm," refers to both the spirits of the departed who reside in the underworld and that underworld itself.

Ruled over by Koschei, who knows every soul, along with their allotted death date and how they died. After the judgement of Shüükh, souls are directed either towards reincarnation if they were good people and if they were judged not to be, they would spend the rest of eternity working in the mire of the "third realm" bureaucracy.
