Heaven

Heaven is the dwelling of God, angels and other spiritual creatures. It is a vast dimension separated into several different heavens, numbered to at least seven.

It is described as having a crystal-like floor, burning walls, and an endless vast sky with model constellations above.

Mortal souls arrive at the gates of heaven, presumably for an afterlife in one of the heavens.

Enoch's office is in the seventh heaven, close to the Godly chamber.
