This is developed for my campaign: Quest Against Destiny (feel free to use)

Campaign Lore:

You are one of the ten souls brought back from the glimpse of death by the combined power of three divine entities.
Mystra, Kelemvor and Oghma saw in you the spark that makes heroes and they are in dire need of help.

Therefore, you awoken anew in Faerûn, a world governed by gods, magic and monsters. Since as a soul you can’t do much, you’ll be given the body of a freshly fallen adventurer. For you as for him/her, it is a new chance for a second life but this one will not be as easy as you thought. Indeed, you’ve been tasked to accomplish what even the deities cannot, bring back the Stylus of Destiny to the realm of the gods.
