The Veil
The Veil is the metaphysical boundary between the Astral Plane and the Realms Beyond. Mortal spirits can pass beyond the Veil once they are released from the Nine Hells. The spirits of Elves and possibly Dragons are reported to pass directly through the Veil — the Hells cannot trap them.
Life and Death in Metamor has more information on that process.
