A Devourer Class Black Hole is a black hole that exists in The Structure Of Everything. It is a black hole that devoures the space-time of Universes. It is covered in space-time. The black hole first starts attaching into a universe. Then, its outer layer of space-time is merged with that universe. It starts pulling all of space-time into it. Finall, the entire space-time of that universe becomes part of the Black Hole. If conditions are right, a universe can exist at its edge. Or if the black hole reaches the right side, the universe's contents can exist at the black hole's edge.
