I've found you again... (Undertale story)

Some wish it was a nightmare. But it wasn't. This happened a long time ago. No one knew underlust could grow so powerful. Well, it did. The main reason why the AU's that got taken over were taken over due to the creator, the dream protector, and the innocent blueberry went missing. It was may of 20XX, that Error, Dust, and Nightmare found the 3 protectors, with a crossy friend of course.
I dont own undertale, or any of the AU's besides this small little 'AU'.
