Ahh, Crossmare, one of my favorite ships in the whole Undertale universe...

Synopsis:

When Cross and Nightmare see each other, Cross, feeling pity for Nightmare, and on the other hand, Nightmare, didn't care and just wanted to die to make everyone happy once again. Will Cross successfully motivate Nightmare?!

Forget sin, no smut. Also, I don't own the cover, credits to that creator.

(Reason why Nightmare's face is not shown in the cover because depression, succ it kiddies. Also Cross, no calling him senpai or Dream will kill you.)

Undertale and its AUs belong to the respective creators.

(REWRITE OF THIS BOOK IS UP! It is called "Obsessive Love".) (I do not own the cover, Undertale nor any of the characters besides my OC's, they belong to their respectful owner. For some reason, I just see Error in the front instead of passive Nightmare.) Error, Forced God of Destruction and Destroyer of Universes was largely unknown unlike Ink, the Creator and God of Creation. Their fights were unseen by the AU's, none of the Monsters knowing about the Destroyer as Ink doesn't want them scared and Error gave no shits if anyone knew him or not. But Error's job is a complicated one, one that he is forced into, and he has to get involved to destroy the worlds. He doesn't touch the Original AU's, but the copies that Ink makes have to go. It was only a matter of time before something happened. Ink, in a middle of one of their fights, blinded Error, hurting him much more badly then ever before. In panic, Error ported into one of the Original AU's. Ink, fearing what Error would do, tells Dream about the Destroyer. Now the hunt is on for the broken, blinded skeleton. Meanwhile a blinded Error has been taken under the wing of another powerful Monster who has fallen for the broken Destroyer at first sight. But sweet love is truly beyond him. It is a obsessive love, a unhealthy love unlike any other. Nightmare would do anything for Error, and would do anything to keep him by his side as he goes about taking over all the AU's. Now to convince Error that he should be his and his alone.

⚠️ WARNING!⚠️ Viewer discretion is strictly advised! Dark themes such as suicide, self-harm, depression and others will be mentioned and some will be heavily descriptive. There will be foul language up ahead. And whole load of them. If things like these disturbs you in any way. Please proceed with caution! That's all! Thank you! ⚠️END OF WARNING⚠️ A SENIOR HIGHSCHOOL THING WITH DORMS!!! :D Yeah, I know, lame description. But I'm lazy. I assure you that the story isn't as lame as the description. Just... Don't judge the book by it's cover. Alright? Good. Now... ONWARD MY MIGHTY STEED AND READ ON!! :D ~*~*~ DISCLAIMER! I do not own any of the characters and AUs/ATs mentioned in the story and chapters! The only thing that I own is the plot and story itself! The reason why I chose to make this as "All rights reserved" is because if I put in "Public Domain" or perhaps "Creative Attributions" and etc, people will get the idea that they can edit this story of mine, or even claim it as their own. And I don't want that, I've gone through a lot of shit through me making this story overall. And knowing all that hard work will go to waste upsets me so fucking much dammit. Thanks for reading my rant n stuff. See ya. ~*~*~ INSPIRED BY MY HOMIE'S BOOK: "UNDERVERSE HIGH", so she was inspired by another peep's book which got ME inspired to make THIS book XD. Anyway, check her out! This is her profile; @Fanfomtrash

Warrior Cats x Undertale Multiverse Crossover ~~~~~~~~ Since the Multiverse was created, the Creators have been fighting over the AUs non-stop. It was a horrible, bloody war that lasted centuries. Many were killed and many were cast away as outsiders. One day, the Creators met in an AU called Dreamtale, and after another battle, the dead came down from the sky as spirits, and the fighting ceases. They told the Creators that were alive to unite, or they would die. So that's what the Creators did. They united. They- and their AUs inhabitants- created Clans. They all lived in Dreamtale, surrounding the Tree of Feelings. Generations passed and the Clans had never seen a war so horrible since the War of the Multiverse. They lived in an almost-harmony. Until Nightmare came along, that is. ~~~~~~~~ Hiya! It's me, Sighnerd. This idea came to me in a dream, so I'm making it a reality. I love Warrior Cats, and I love Undertale, and I tried once before to merge the two, only that didn't work because I wasn't as experienced in writing as I am now. You don't need to understand Warriors to read this! It'll all be explained. The only similarities are the fact that the Sanses (and some not-Sanses) live in Clans, follow the Warrior Code (which will be explained in the introduction), they aren't cats (that's just weird), they have the same roles (tweaked a little because they aren't cats), they follow the same customs, and some other small similarities. Kind of a slow burn. That's what I'm going for, anyway. There may be a few toxic moments, but it's Nightmare, so it's fine. Right? Art and characters (except for the Empathverse Sanses and Sigh) do not belong to me! Neither does Warrior Cats. Cover art belongs to ProductionRoxy. :D My interpretation of the characters, but I'm keeping it as canon as possible. They're tweaked a little to match the Warriors setting.
