    Summary

    The joys of being the only mage in an Underground society full of humans that wanted his head cut off, put on a stake, and burned... they were truly limitless. Being constantly targeted for harassment and always getting picked on for fights, having to constantly be on edge and defending himself and his abusive younger brother from the outside world that wanted them dead.

    On top of everything, he fucking hated his job.

    What he hates more is breaking a promise.

    What he hates a lot less is a skeleton monster that enters his life suddenly and changes it just as fast.

    Summary

    I meant to die.

    I'm trying to gain my bearings and earn my place in this new world. At first I thought it was just so I would never have to go home, but maybe it's also so I can stay with the bizarre, slovenly mage I have come to care for.

    I've heard of soulmates... Could this be it?

    (Nah basically I have been obsessed with Undertale for far too long and I have far too many head canons, and I need to put them down. Switch the monsters for mages since I don't want to have to deal with ecto-peens, but basically this will be a drawn out romance between Sans and Y/N. I'm serious, they won't meet until a few chapters in and they won't be touching pinkies till we are at least in the double digits of chapters. I have elaborated on the basic world building Toby created and also build on his characters, so there's different sets of rules they play by, and the plot is pretty different from the game. Idk man I'm bad at selling my shit lol. Kinda rough subject matter, read the trigger warnings ok?)

    Summary

    On the first day of 6th-grade, Red Gaster meets Sans Serif. The two of them grow up together, become best friends, have adventures, discover a new species of monsters(?), and eventually fall in love. (It all feels really familiar.) It's a coming-of-age story that has (maybe?) happened before and (might?) happen again.

    In the vein of Catsitta's 100-word-a-day drabbles, this story will be told 250 words at a time with updates each day. It's best enjoyed in entire work mode.

    This is a PREQUEL (sort of? I guess it depends on how you look at time travel) to my first daily drabble, A Bitty Escape. This can be read on its own, but will probably be a whole lot more interesting if you check that one out first.

    Summary

    All I wanted was a break. Some time away from my Cyber Security job! I guess that was just wishful thinking...

    I woke up with my head throbbing with blood running down my forehead. I was on a beach surrounded by blood and gore. I was so screwed...

    I really should have played more attention in boy scouts...

    Summary

    My Attempt at the 30 Day OTP Challenge involving Crink. A mostly fluffy story about Ink and Cross deciding to meet up in secret behind both their teams' backs, totally to hang out as friends, only to end up falling in love with each other. Fairly slice of life without a whole lot of plot outside of the romance.

    Summary

    A butterfly beats its wings and all that.

    Sometimes, the most important events may be set into motion by the tiniest thing. Some decisions cannot be planned beforehand.

    Life is never predictable. Science isn't either. You do the math.
