Is anyone planning on officially writing about the spine thing? It's the "source of all living matter"/"organic material"/"Devil of All Earth".

Also, that thing is like a parasite. It lives on through spinal fluid and interdimensional paths connected to people. It needs people (Subjects of Ymir) to keep carrying and passing it along from generation to generation.
