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.

There's been discussion on whether it should have a page on the wiki, but it's not going to at the moment since it has no proper name and everything we would say about it would fit on Ymir Fritz's page.

We don't even know if it's a living being at all. When writing the wiki's chapter summary I referred to it as a "substance" to be as non-specific as possible. All we really know is that it's rather slimy/globby-looking.
