She'ol it a large purgatory dimension that exists in the Astral space surrounding the Earth. It is a place of darkness to which all the dead go, both the righteous and the unrighteous, regardless of the moral choices made in life, a place of stillness and darkness cut off from God. It is ruled over by a Tribunal of Judges composed of beings known as Shades. They are the ones who decide who goes where. It is the metaphorical sorting pile of Spirits where they will be tested to ensure their true essence, good or evil, once a result has been established then the spirits are passed through the Great Wall into either the higher realms or the lower realms.
