For centuries, "Nightmare" had tormented the Multiverse, nourishing too much negativity causing havoc and destruction of both minds and worlds. Until it suddenly came to end when his gang of lackeys secretly worked to help take down Nightmare successfully. And it WORKED. Nightmare was struck down and heavily weakened by Dream, and a little bit of Passive came through and that was enough for Dream to plead for the saving of his sweet brother.
But can one fix something like this?

Nightmare was new. Sort of. A husk of his past self, he attempts to heal from things he can't remember.
