Olam Tzalmavet

"May you find sanctuary within this foreign setting, removed from time and life."

- Hant Nirjara to the Reprobates, Chapter 1

Olam Tzalmavet (オラム・ツァルマベット), commonly referred to by souls as the Realm of Null (虚藩), is the land of the dead within Ellipsis.

Located between the realms of Heaven and Hell, Olam Tzalmavet is what humanity commonly refers to as. Once a human dies, their soul is transported to this location where it waits to be judged by the realm's king, Nullifuge Samvara.

Description
After death, the human soul is taken to Olam Tzalmavet by Samvara; the embodiment of death and its final judge. Souls wait here where their souls are weighed by the sins and virtues they committed during their lifetime. If a soul committed far too many sins to the point where it greatly outweighs the good, they are cast into Hell. On the opposite side, if a soul has lived their life doing good works and virtuous deeds, they'll be escorted to Heaven.

For souls that fall in the middle, they are sealed by Samvara within his palace: Thaumiel. Within Thaumiel are the souls of countless individuals that Samvara collects. Every four-hundred years, Samvara selects one-hundred of these imprisoned souls and forces them into the Rings of Rebirth. The sole survivor left standing at the end is "reborn" and sent back to Earth just as they were before they died; giving them a second opportunity to rebuild themselves for a chance at getting into Heaven.

After the end of the Rings of Rebirth, any leftover souls that Samvara collected within Olam Tzalmavet are automatically sent to Hell.

Trivia

 * Olam Tzalmavet literally means "world of deathly shadow" in Hebrew. It is also an alternate form of "Neshiyyah", a term used to denote in the Kabbalah.
