Outside the boundaries of the universe lie the raw realities, the could-have-beens, the might-bes, the never-weres, the wild ideas, all being created and uncreated chaotically like elements in fermenting supernovas. Just occasionally where the walls of the worlds have worn a bit thin, they can leak in.
