    Summary

    "Protect humans and keep them safe from harm, no matter the cost."
    Sans had made a promise, and he was prepared to go to any lengths in order to keep it.

    The short skeleton refuses to let you go because you'd only find danger outside the Snowdin village. He loathed himself for poisoning your drink in order to make you weak and sick so that you can't leave the safety of the town. It was a horrible thing to do, but this way you would stay with him and Papyrus.

    He'd keep you safe and happy.

    Summary

    You were just trying to write a school paper about the Core and who made it. And yet it seems no one remembers who did make it, or how the Core even came to be. You didn't expect to be contacted by the very man you were looking for, nor did you expect wanting so badly to rescue him from the Void itself and bring him back into existence. You don't know if you're doing it to prove something, you don't know if you feel like you're responsible for helping him. You do know, however, that he's been alone in the darkness long enough.
    You didn't plan for this to happen, you didn't ask for it to happen to you, of all people.
    Are you sorry it did? Do you regret your actions, your decisions?
    Not one bit.

    Some other times, it takes much more than that, and it certainly becomes more than what people can handle.

    Summary

    In a timeline where the barrier was broken by both Chara and Asriel and Gaster never disappeared, Gaster decided to wait for children. He took his time, waited until he was a well established name in multiple fields in science and then took steps. Once he had children, however, he never expected they would be as much work as they were even if they were one of the few joys of his life. Enter you: Zelda Emmerson, live-in Nanny extraordinaire.

    The last family you worked for no longer needed your services, so what’s an out of work childcare provider do? Find new children to nanny, of course. You won’t pretend you understand everything about this strange little skeleton family: Papyrus, the infant who seemed incapable of being anything other than larger than life; Sans, the tiny genius six year old who was already easily understanding concepts you could never wrap your head around; and their father, the infamous grouch and scientist, Dr. W. D. Gaster.

    With all the quirks and oddities of living with such a trio, there is one thing above all else: you were going to have a blast.

    Summary

    *Hello lovelies~ I wanted to update here, the plot(arc?) bit will be wrapping up soon! Deltarune helped give me the burst of motivation I needed the last few days, and I've written quite a bit ^-^ That said, if now or in the future you all have any more ideas for things you'd like to see happen, let me know! I'd love to keep going with the fluff after we finish the next couple chapters, if you all would too :)

    *Here's part of what Dovequeen gave that started this:
    "The AU would mainly be focused on the skeletons being little kids, them adjusting to life in the castle, Toriel trying not to get attached (for fear of forgetting/replacing Asriel and Chara or losing the two skelebros like she did with them) and Asgore trying to fill the v̸̨̧ơid̵ his kids left with the skelebros and forget his grief by 'raising his new kids'."
