Walking These Halls
Sans Aus in a school what could go wrong? Lots of things, do people die? I don't know, but ships are included. You could say it is a slow burn kinda thing or it went pretty quick, but chaos ensues and it isn't my fault. (FandomError)

Error on shorts
The title also these are my lower quality writing I may be updating some of them to fix grammatical mistakes and change them to my current writing style. (I recomend that you skip this and go straight to the third book)

The sweet lilac behind the cold cyan
What if the corruption that invaded Nightmare's mind after eating the apples disappeared? When he woke up after a long sleep Nightmare found himself in a place he didn't know. He couldn't sense his brother or mother anymore and was covered in some weird goo. The last thing he remembers was the fight he had with the villagers that wanted the apples. Will he be able to go home back to his family? Does he even truly want it? This fic had been inspired by little-inky night switch Au! I can only recommend you to see their art!
