    2# in Cream, 16/Oct/2021 4# in Nightmare, 26/Feb/2022 1# in DustHorror 29/June/2022 Sooooo I've been seeing a lot of these on YouTube with Gacha Channels and I thought 'Hey! Why don't I WRITE something like this? BUT WITH MY MULTIVERSE THING!' So here this is! Just know NOTHING in this is canon to the actual story! It's just a break for me :3 BUUUUTTTTTTT There will be a few things that will reference the canon story [Which is currently unpublished due to me changing a few ships and needing to rewrite the WHOLE THING] Warning: -Cussing -NSFW at times (As in gore and all that)

    Nightmare lost everything. Everyone left him the moment he showed weakness, even though that was when he needed them the most. Killer stayed. Killer wouldn't leave him. Killer would always be by his side. He had sworn to do it. So Nightmares figures were gone except for the king and queen, had either defected to the opposing side or simply left. Dream clearly had the upper hand in this game. But nobody expected outside interference. The only question was which side they swear their loyalty to. Will it be the warm, intense sun or the cool, gentle moon? [Besides my Ocs, I don't own any of the characters]

    Artbook where I'll redesign Undertale AUs and re imagine their stories and personalities ^o^ Please remember that I'm not a professional and that while I may criticize the original AUs I'm not saying they are bad and I like them still very much and I'm doing this for fun ^•^ OG Dreamtale belongs to Joku (I'll make a better cover once I designed the major sanses)

    Nightmare. You should know my story well. Heh. I mean the other me's story well. If you don't then where the f*@# are living? Anyways, the story of the two Guardians of Positivity and Negativity. Two beings were created to be guardians of positivity, dreams, the golden positivity apples, and negativity, nightmares, and the dark negativity apples of the tree of feelings. Dream and Nightmare, brothers. Dream was treated with kindness, given many gifts, and so on, having many "friends". Though let's be honest: He was treated with kindness so the villagers would be on his good side, and his friends just use the gullible idiot to get the golden apples. Nightmare, unlike Dream, was treated like shit. He was bullied daily, usually ending up with major injuries, caused by Dream's little "friends". Dream never notices and never figured it out. Until it was too late. One day, after so many years of bullying, Nightmare took a golden apple. Mine are just as good as his, right? The tree's apples quickly all turned "dark". The surrounding monsters of humans started yelling and approaching him. In a panic, he took a bite of the apple. He started throwing up black goop and 4 sharp tendrils burst out of his back. He was starting to be covered in black goop. His eyes turned cyan as one of his eye sockets got covered in the black goop. He killed everyone. He became the "monster" everyone said he is. He attacked his brother. Both left hurt, but not dead. He's also known as the King of Negativity and Nightmares or the Boss of the Bad Guys/Sanses Well... Say he tried to take a bite out of a dark apple, but his "dear brother" stopped him. Say Dream offered help with his "friends". Say Nightmare ran. Say he ran, say he ran deep into the forest to never be seen by his brother again. At least, not as the same person. Characters or art don't belong to me! (Drew the cover)

    Nightmare was never one to ask questions, but when his dearest brother, Dream, began to act funny, he was obviously wondering why. But along the way, he finds that the word 'brother' didn't really fit the positive guardian anymore, nor did it fit their relationship. - - Pre-apple incident Au.

    No fleshed out plot we write like there's no tomorrow. Minor ship moments here and there but plot isn't focused on shipping. After noticing his brother's been acting off as of late, Dream is determined to figure out what's going on. With the help of his teammates they make a life changing discovery, one that would have Dream questioning both his life choices and if he wants to continue being a Guardian.
