"Anyone can draw a map, boy - there's no more difficulty in that than laying brick. What makes maps useful is when they are so proper, so precise, that they are living images of the places they represent. Encompassing knowledge of the geography, and mastery of the very space itself - that, child, is cartogramancy."
- Sage Pakpao Sasithorn, Chief Lecturer, the Ezagun-Darkbolt College of Cartogramancy
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.
