Sans and Papyrus were your best friends until randomly they just cut off all contact with you. This went for everyone else in your life so it didn't really hurt that much when they did. The only question is why they didn't do it sooner. So after two years of loneliness, what was originally a drop off turned into a hospital trip, a broken leg, and your once best friends now homeless. What should be happening is them owing you a thanks for rescuing their so called, "Cousins" from a fire. Yet here you are offering them a place to stay, at your big ass mansion for the next eight months. So now you live with the people who abandoned you, along with their so called "family" who by the way don't really like you because you're a mage, but it's barely relevant to the plot so - What could possibly go wrong?

Decades after the monsters were imprisoned underground, the humans have found a new prey to hunt. Despite hiding from the humans for centuries, witch trials swept through the world killing almost all surviving mages. Almost all. The reader is one of the few mages still alive through the horror of the witch trials. Fleeing from humans, she falls into the underground. But is it truly safer than the world above? A reimagining of War Zone, where the reader never met Grillby or any of the other monsters and must navigate the surface and the Underground after the war.

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
