    Summary

    Once long ago, humans and monsters lived alongside one another. During this time it was an age of unparalleled magic and strength in the two sides.

    However, the great war happened, and with the absence of monsters mages slowly died out. After all, humans are not inherently magical. With no more magic to keep the blood lines going, magic is all but a fantasy in the humans of today. That is, until an eccentric billionaire decides the mages need a come back.
    Looks like you and a few others are just the right subjects to get the ball rolling.

     Oh right! There is some swearing in here.

    *WARNING* Some people are very sensitive to kidnapping/abduction themes. While I assure you, I probably won't go too dark, it is a bit... muddy in here. Tread lightly.

    Summary

    Decades have passed since the defenders of creativity and positivity have had their fallout. Neither have worked together, nor spoken, nor even acknowledge each others' existence. However, when the world is as bleak as ever, and the two are forced to cross paths, maybe now's a better time than ever to work together.

    Summary

    A dirty glitch slips from Error's grasp, taking Classic Papyrus and leaving chaos in its wake. Sans accompanies Error in attempting to stop the anomaly before further damage is done, and to help save his brother.

    Error could salvage this mess. He had to.

    But he didn't realize he needed Sans to salvage him, and perhaps the other way around.

    This story contains mentions of past abuse, rape, and other things. If you don't like these types of things that I would highly suggest you turn away now. If you aren't bothered by those kinds of things come on in! Hope you enjoy your stay at the House of Skelebro's.

    Summary

    All of the different Sans and Papyrus copies from the AU are here and they are all living together under one roof! The original versions of themselves! What is the catch or the reason? That is rather simple, their own universes were all destroyed, the kicker is that it was not errors fault, they don't know what happened, but it cannot be fixed. Now, several years later, they are all coping with the losses of their other friends while making new ones.

    There seems to be someone who wants things to fall out of place though, and he is targeting the original Sans to get it done. Now all of the AU have to band together closer to get him back after he is taken! How is this going to end? They will need to go back to their own universes to look back and see what they were taught that was important to them when they had gotten to their newest home. After all, lessons taught by friends are one of the most valuable things that you can gain, lets just hope it is enough to get them out of this.

    Summary

    It's adorable.

    Told from San's point of view, as he meets a girl on a rainy day.
    He thought it was only a one time occurrence, but it happens again and again.
    Who is this mystery woman with the navy blue umbrella who wandered into his heart? Could it be... you?

    This universe is built as a parallel to the story "So... Where Do Mages Come From?"
    All the characters from that story will be found again in this one. Though this universe stand apart from that one. It's happy and romantic and fluffy and lighthearted. Sure to keep your bones warm on a rainy night.

    Summary

    Monsters had breached the surface just a short year ago now, not that you'd know much about that. Yep, you were a bona-fide hermit, a stay at home artist and to actually pay the bills, you also ran a small financing business from home. Only when that business gets sent under by a few smucks with more bucks you'd ever see in your life, time calls to get a new job, but could this new gig be a little more than you could handle?

    Summary

    Geno was just a normal human who was struggling with a lot of problems. But if he thought he had problems in the first place, it was nothing compared to when Death came knocking at his door...literally.
    Introducing Reaper. He's a god of death who decided that, with all the violent deaths that happened on Earth, it would just be simpler to live on the planet so he could do his job faster (and easier). He just needed the perfect roommate... Ah, how about that fellow who looked to be half alive. When he died, Reaper could just take over his home. Problem solved.
    "hello, human. i'm your new roommate."
