Despite living on the surface and a part of society at last, Sans can't bring himself to feel happy - hell, he can't even bring himself to sleep. As a matter of fact, all that truly features in his life is the happiness of his brother....a thing that he is more than satisfied with. Or, at least, he thought that he was. One small human child was about to change his and his brother's lives forever. ~ This is a commission from the lovely Alextris! ^-^ There's going to be a few dark themes, so please read the tags - but rest assured, this will be a predominantly healing tale of fluff and family :3 With that said, I hope you enjoy! <3

Gone. In a single moment, in the blink of an eye, everything you have ever known or cared for is eradicated. Hopes and dreams, traditions and stories that date back centuries have been erased without thought or care. Nothing matters and no one will ever live again to pass on the memories and stories of what was lost. Except you. You are the anomaly, the glitch that survived when all else could not. When your universe was destroyed, you found yourself stranded, alone, afraid in a white world without end. But there's little time to rest when you discover that your universe was merely a grain of sand on a much bigger ocean. Whole other worlds thrive in different plains of existence, and they're all going to war. In a desperate power-struggle for the upper hand, you find yourself an unlikely ally. The future seems certain, chaos will win and the universe will be plunged forever into violence and bloodshed. And it will take a lot more than a miracle to win.

Moved from AO3 because of reasons! "You are the only maid (or worker in general) that serves for the Skeletal Household. It's a skele-ton of work, but you manage by keeping onto a fairytale dream."

It's been over a year since the Underground opened up and the monsters living under the earth swarmed to the surface in their thousands. The human and monster governments are taking their sweet time coming to any kind of agreement regarding monster rights and citizenship, but for the most part, in the less politically-active parts of the nation, life continues as it always has. In your sleepy little town, there are bills to be paid, tables to be waited, and few to no adventures to be found. So when two skeleton monsters move into the empty house near the café where you work, you welcome the changes they bring with them. You knew if you let them into your life they'd make interesting friends. What you didn't expect was that getting to know these remarkable strangers would be like coming home.

MSA x Undertale crossover. Their souls pulse softly in the little glass cylinders. Purple, blue, orange. The colors of my failure. I am not ready to say goodbye.

After much research and theorizing, I've decided that I'm going to attempt it. It's risky, but I'm so desperate at this point that I'm willing to put my own well being on the line. If I survive, this may just turn out to be very... interesting. This is my thoughts on the origins of Sans and Papyrus, as well as their connection to Gaster. It will be connected to the ZanaTale timeline (or, in otherwords, my Sans x Reader fanfic "When Two Souls Meet"). Loosely inspired by the HandPlates AU by Zarla. Awesome cover image by Dweebycake.

Sans has lived through countless timelines. He's seen the kid make friends with everyone, only to give up in the final moments. He's seen the kid killed, over and over and over again. Sometimes, he'd even done the killing himself. And no one ever remembers. Not even the kid herself. It's an exhausting cycle, one that never seems to end. But there's something different about this run. Another human's fallen down... the kid's sister. Please note the the story is primarily on Quotev, so updates to Wattpad may be late, or lag behind that of Quotev. The story also has the potential to become mature. (I haven't decided yet.)
