Singing Her Own Song: Profiling Ellen Lancaster
--by Jamie Easton, New York Times
Ellen Lancaster is a woman who refuses to be labeled. Eschewing recognition, this powerful Delta seeks fulfillment through helping others find their voice. While her tale might seem one of rags to riches, she sees only a lifetime of riches, many of them far more precious than material wealth.
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.
