Mortis

Mortis is the "scientific" name for the afterlife.

Information
This is where the ghost girl Azana went after she was freed. Not much is known about its mechanics, or whether it is connected to the Luminous Netherworld. It may be a location within, beyond, or simply a concept connected to this location.

Trivia

 * Mortis means of death in Latin
 * Either this or the Luminous Netherworld is called "Prekt's Realm"
