"Welcome to the rogue dimensions. Here you will find a maze of energy where matter is evolving to a most deadly purpose.
Creatures from these labyrinths are popping into our existence and destroying all that they touch, from cell to sentient. That is why you are here, to stop the pan-dimensional evolution and save the world!
Stay calm, study the environment, and tread softly until you figure out just what the hell is going on in there."
