Caged (Nightmare X OC)

Memories of a Forgotten Life

It's been 4 months and Sidney still hasn't given up. Flowers, poetry, chess, reading, cooking, almost everything. Almost. She wouldn't just give her body to Nightmare. Not until he admitted that he loved her and proved it. He did neither. Now, she was cleaning up the library a little. It wasn't a huge mess, just enough for me to want to clean it. I reshelved book after book before something caught my interest. It was a book, a small, extremely worn, children's book. She couldn't help but take a deep interest in the small story. Probably due to the title. 'The Story of Dreamtale.' She didn't know what Dreamtale was, but she was ready to find out. She tucked away the small book, saving it to read later. She continued cleaning up, straightening the furniture and dusting the place. After she finished, she looked for a place to read, settling in one of the dark Bay windows.

A long, long time ago, when the formation of the universes were in their primary stage, we had already known the existence of three vital trees for the life of evey being on every universe, the tree of life, the tree of magic, and the tree of feelings. They were vital to the multiverse and each one was in a different universe, protected by their own Guardian. This is the story of Dreamtale, the universe where the tree of feelings lived, who's fruits were apples, half black, half gold. The black ones held negative emotions, while the golden apples held positive emotions. The tree of feelings kept the balance of emotions and thus was vital to the multiverse. However, there were some people who obtained more negative emotions than they should have gotten, and they intended to damage the tree in an attempt to obtain one of the golden apples. One of the bad people managed to servely injure the Guardian of the tree, whose life force was tied to the tree, meaning that if she died, the tree would die. The Guardian killed the aggressor, her only choice so that they wouldn't die was to fuse with the tree, and then she would save it, but if she did that, then the tree wouldn't have a Guardian, it's fruits could be stolen with ease. Scared because of all the blood she was losing, she decided to use the magic of the tree to create life. Two beings of light were made of pure positivity and negativity. The yellow one of positivity was named Dream, while the dark purple one of negativity was named Nightmare. Using the form of Sans from Underswap, the Guardian created two vessels for the new Guardians. After putting their energy in the vessels, she fused with the tree. For a long time, it was just the twin brothers. But Dreamtale started to get filled with more and more life. They created towns around the tree. Everything changed for the worse.

"Dream and Nightmare are brothers? Twins? What happened?!" There was only one way to find out. I continued reading. "It seemed that while Dream played with the townspeople, Nightmare was abused. He never told his brother as a way of protecting him. It became to much for him and Nightmare distanced himself from everyone. In an attempt to prove he could protect the golden apples, he instead contaminated them, and they all turned black. Nightmare knew he'd done wrong and didn't know how to fix it. Dream hoped to be able to fix Nightmare's mistakes by using his own positivity. The townspeople, however hated Nightmare for what he'd done. They were going to kill him. Dream tried to stop them, but he was just one skeleton. A voice spoke to Nightmare, telling him him to eat an apple, he knew it was wrong, but due to his fear he-" The book was snatched away be a very angry looking Nightmare. "what the hell are you doing?"
"..."
"never ever read this." He hissed lowly. "... What happened next..? Did... did you eat it? Did you eat the apple?" He paused a moment, looking at the book with an unreadable expression. "i ate all the apples."
"And... you changed... into this?" Sidney asked. "...i did." Nightmare looked away from the girl with a distant stare. "the first thing i did was murder everyone in my au. then i tried to kill my brother for the last golden apple. he ate it though... so i fought to destroy him. turned him to stone to get that damn apple, but it proved fruitless. so i destroyed the tree and moved on to concuring the multiverse." He expected fear, not a hug. But a hug she gave him, crying into him. "I-I'm sorry you went through all that! I'm so sorry, Nightmare!" Nightmare didn't know what to do.
