Faithless

The Faithless were mortal souls who died without having chosen a divine patron. This could be because the mortal never worshiped a deity (or rejected outright the worship of any deity), because the mortal's divine patron had died, or because their divine patron had rejected them for whatever reason. A soul who did worship a deity but did not sufficiently uphold the patron's dogma was instead judged False.

A Faithless soul received only one sentence when it reached the City of Judgment on the Fugue Plane to receive its judgment for its afterlife: the Wall of the Faithless. The soul was bound into the wall by a green mold that held the Faithless (and only the Faithless) to the wall. Over time the soul dissolved into the very substance of the wall.

Demons propagated their kind by stealing Faithless souls from the wall and retreating with them back to the Abyss.
