An offer, a long voyage, a bitter ordeal, and a knife in the back.
A second chance
In a land known only as legend, in a tower that could only be myth, beings of immortal evil wait for freedom. The Ones who Hunger for Pain are coming to give it to them.
You say you have no place to go, friend? That you do not even know, if it is worth going anywhere? I hear there is a place where they might help you.
Conosca abbastanza per essere impaurito, molto impaurito
Motto of Cinque-Parte Polygnostic
A simple mission for a Dragon, but of course, nothing is ever simple with Dragons.
When you sleep, your soul briefly returns to the place where it was created/goes to when it dies, and seeks nourishment. Everybody's soul is created with a little link (or you could say a greater entity calls it back) to that place so that it can return easily, but upon death, the soul returns via that and annihilates the link as if returns.
Also, as an added thingy, you could say the entity supplying the link, or residue of the links themselves, (whichever) is the source of all arcane power.
