Das ist der gesamte Abschnitt zum Thema Afterlife aus dem SCAG:
Most humans believe the souls of the recently deceased are spirited away to the Fugue Plane, where they wander the great City of Judgment, often unaware they are dead. The servants of the gods come to collect such souls and, if they are worthy, they are taken to their awaited afterlife in the deity’s domain. Occasionally, the faithful are sent back to be reborn into the world to finish work that was left undone.
Souls that are unclaimed by the servants of the gods are judged by Kelemvor, who decides the fate of each one. Some are charged with serving as guides for other lost souls, while others are transformed into squirming larvae and cast into the dust.
