“ 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.”
“ Orchound - A large canine with tusk like bottom teeth. Orcs bred these dogs to help them in battle by grappling with foes, and dragging them to the ground. Despite their fearsome appearance and loud bark, they are trained not to kill, this is the venue of the warrior, not his hound.”
