Failed destiny with mistook fate

Somehow, overnight, Ink, the creator and Error, the destroyer both loose their minds.
Their voice changes, their eyelights become thin, they twitch, and randomly cry or scream out in pain or anger. They'd talk in gibberish and get angry so quickly. Amd the battles that came... they destroyed everything in their path. Aus, people. Everything.
Their former friends, Nightmare, the gang, Dream, Blue, they all agree a stop needs to come to this.
But what they don't know is there's more to this than it seems

I don't own the art in the cover, I used Picsart cause I'm lazy af
