Nightmare finally did it. After years of chasing, fighting, and failing, he finally did what he'd always set out to do; he killed Dream. And victory tastes sweet. Until it doesn't. Dream may be dead, but positivity sure isn't. Turns out, the Multiverse likes its balance - it took Dream's powers and job and transferred it to another host where it deemed it would be the safest - in Y/N. Nightmare does what anyone would: he goes after them next. But for some strange reason, no matter what he tries, he physically cannot do harm to them. Confused and still trying to sort out their own problems, Y/N is dragged into Nightmare's world as he struggles to find out how exactly he should kill them.
