Felice is an Elven girl with a lot of features to her. She’s kind to most, unless she meets there need to shed of blood. She’s both physically and mentally strong and lends a hand towards others. She has a secret to her that no other has.
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.
