    He knows he'll be dooming them if he falls, but he's tired, his body is breaking apart, held together on a higher being's whim only. He wonders if there'll be another to replace him. He wonders if there will be none. It's rather silly, really, since he won't even be around to witness that. The crowd, the rage and bloodthirst palpable in the air will ensure that. If he does not fall on his own, others will force him to. Or, in other words, the typical start of Error being forced to jump into the Void one way or another, in this case into the NaJ universe! The cover art belongs to irodimmatcha on deviantart(will take down if the artist asks me to)! Updates will be highly inconsistent. Edit: Now cross posted on Ao3 under the same username!

    Ships; - Errorink/Errink (Error x Ink) - Dustberry (Dust x Blueberry/Swap) - Kreme (Killer x Dream) - Crossmare (Nightmare x Cross) - HorrorLust (Horror x Lust) Trigger warnings; - Self-harm - Eating disorders - Violence - Sexual scenes - Strong language - Mentions and suggestions of rape After ending their fake relationship, Ink and Dream's friendship is tense and unhealthy. It doesn't help that the Multiverse disapproves of their breakup, and Nightmare has grown stronger thanks to the negativity that stemmed from the event. However, things start to turn around after Ink and Error's 'friendship' takes a turn for the better as they realise their feelings for each other. But, what about the others? Will they eventually get together, or will their conflicting personalities collide with each other and make it impossible for them to get closer?

    Reborn as the guardian of positivity, you find yourself in a strange new world, uncertain of what it may hold. Navigating it isn't easy with gods like Nightmare and Error trying to strike you down every step of the way. But unlike the previous Dream, you have nothing to lose, and are determined to forge a better path than the soul whom you have replaced.

    The right thing to do: everyone has their definition of right and wrong. Should you always follow your morals? Or is sometimes the right thing to do to abandon them, to sacrifice them for the sake of everyone else's safety? Error, Nightmare and the Gang know no MERCY. No matter how many times they're defeated, they never stop hurting people. Will the Stars keep following their morals? Or have HoPe, MERCY and the Pacifist way become obsolete?

    Sans might be free from Error, but that certainly doesn't mean he's happy. Post-Errortale, Swap!Sans escapes from Error and his timeline goes back to normal, but now Sans has to live with the lifelong trauma Error gave him and readjust himself back into society. It's going to be very hard, especially since he appears to be the only one who remembers the incident. Errortale is by loverofpiggies. Just a one-shot, sorry! I might continue it. Maybe not.

    So, this was my first book I made on here! This story is unfinished, and I don't make parts very often..But I still try my best to make the parts of some quality at least when I do! No sense in putting out a part just for it to be something like 10 words long, ahah- (No offense to anyone that may do that) Don't expect it to be professional or anything, though in my opinion I'd say it's a good start!
