Summary
Magic and reality mix together. On one side, there were the most religious humans, those who repudiated the existence of magic itself.
On the other side, the Vikings, a brutal people, in search of ever more important conquests. They exploited every possible opportunity, to win.
And then there were the monsters. Strong enough to defeat any opponent... But with souls not strong enough to take control.
In all this, you are in the middle... What happens when a human with magical powers like you, ends up in the middle of a war, of which you did not want to be a part?
You wanted to stay away from all this... But a pack of very stubborn skeletons will drag you into something much bigger.

Summary
The Barrier is down, monsters are walking the streets, and reality just got a lot stranger.
Rhea is human, unprepared, and stuck in a house full of wildly different, unpredictable skeletons. Some are warm, some dangerous, all impossible to ignore. Pulled through a mysterious machine, she’s trapped under their watchful eyes while the multiverse starts leaking into her life.
Rhea navigates the household of chaotic, flirtatious, and often deadly skeletons, while trying to come to terms with her new fantastical, but very real reality.
Darkly funny, magically strange, and dangerously charming. An urban fantasy reverse-harem story about survival, trust, and learning to live among the bones. -

Summary
Sometimes life throws you a curveball. For you, your curveball was going to bed looking like a human, and waking up looking like a monster.
A skeleton monster to be precise.
With the barrier breaking, a large surge of magic descended on the town you live in, and transformed you overnight. Unsure what to do with you, and the others changed, you're ushered into a facility until a monster with similar magic can take you to teach you how to wield the now uncontrollable magic you've been given. After waiting in this place for four years, you'd given up hope that anyone would ever want to take you.
What a surprise for you when you find out that someone does. A lot of someones.

Summary
Error has a single, thankless job: tear apart every last abomination Ink dares to call an AU. It's routine. Easy. And mind-numbingly boring as hell now. And no matter how many universes he erases, the voices never shut up.
And when Nightmare offers him a place to crash—complete with chocolate and silence—Error sure as hell didn't accept it.
But he doesn’t throw the offer away.
Something’s building in him, and for once, it’s not just rage. It’s something worse.
---
Or, how Error slowly gets closer to Nightmare's gang (as much as he begrudges it). -

Summary
It isn’t fair. You just wanted to be left alone…
Isn’t this what you deserve though? You broke the rules, everyone was perfectly upfront with you on what the conditions for being allowed to live were. It’s the right thing to do, what’s one more time?
Maybe they’ll forgive you if you let them… maybe they’ll forgive you.
You look up at the expressions on the monsters’ faces and you know in your heart that this isn’t going to stop.

As you get friends and foes alike, you notice that not everything you know is trustworthy. Especially when you're a little lost skeleton with questionable ability to feel.
After all, anything could happen in a place this big.

26 Oct 2025
Tags
Summary
The Multiversity- a college run by Core Frisk and their Omega Timeline Council. It welcomes students from across the multiverse, no matter their backgrounds. While there are always some challenging students, this year boasts an exceptionally wide assortment of unique faces. Many of whom are neither thrilled to be there, nor fans of their administrators.
In other words: A college AU featuring all your favorite Sanses. True stories from wild college experiences sprinkled in with general chaos and disaster as skeletons from various backgrounds are shoved together in a classroom setting and given way too much freedom.
