Summary
The District of Mount Ebott, or the DoME, for short. The heart of the metropolis, the city, the only territory within the states with the highest monster population for the past few decades. It was only a strike of circumstance for this blighted girl from the Midwest to find herself thrust in the core of it all, such not without three souls she'd do anything to protect underneath her roof.
Monsters–mobsters–mafiamen.
Who knew she'd end up as the most relevant piece of the puzzle for the tensions between the Crowns and the Canines. Such a poor, indiscreet woman with no more value than the stick up her ass surely couldn't attract too much attention from the wrong crowd.
Well, whatever it is they say, keep your hide close, and your enemies closer.

Summary
Life isn’t fair, case in point, you didn’t expect to be trudging through the snow to the corner store to pick up some much needed, over priced, feminine hygiene products while trying not to bleed all over yourself all because you failed to remember to pick them up with your normal shopping. That’s the thing, no one ever said life was meant to be fair did they?
~*~
Promises were just words, promises of home, safety, love. Only ever worth something if the person kept those words close to their soul. That was something he learned pretty damn quick. Built for love, to be a friend, a companion, tossed into the rings to be a fighter, something he was never meant to be. The only promise he knew he could trust were the few he made to himself, the promise to never fall for the sweet lies of a pretty face again.
~*~
What happens when two souls who honestly need each other, don’t know how to open up and trust? Can love, trust, and home be found when the world has proven that trust is a dangerous thing? Can they get over the hurt that this unfair world has piled on them? Open up to each other and maybe, just maybe find the home they both need?Series

Summary
You have had a tough life that has left you scarred and untrusting of others. Growing up in a mage family obsessed with power and ensuring their lineage, you are the black sheep of the family, possessing a green soul of kindness and excelling in healing and growth rather than the combat magic your family specializes in. Trapped in a loveless relationship with a controlling, abusive partner chosen by your family to ensure a 'proper' match, you live in fear of triggering his anger, often resorting to your magic to heal yourself. Every aspect of your life is controlled by someone else, leaving you resigned to survival and scraping together what happiness you can.
What you could never foresee is the way a miserable night out with your fiance would lead you to a drunken one night stand with your soulmate.
Nor could you predict you would have 9 more soulmates out looking for you.

Summary
“Not so fun being stuck in some loop right? Trying to fight to protect what ya got, not getting a choice in it. If I had the choice I wouldn't remember either.” The words oddly felt comforting. Link let out a slow breath, closing his eyes for a brief moment.
He didn't feel alone for the first time in a long time.
And that?
That was terrifying.
“To be honest, I kinda gave up a while ago. Just sat back and let the chaos go on, felt like nothing I did mattered anymore. Everything would just be reset anyways. Stopped caring what happened, that was until you showed up.” The skeleton’s eyes bore back into the Hylian.

Summary
Two souls in the Underground, intertwined by fate and by a prophecy that keeps them apart.
Heads up before you read:
In this fic, Chara is alive and far from a good person. They’re not a mindless killer, but a narcissistic kid. This is not a fluffy Charisk story. Chara and Frisk’s relationship is deeply toxic.Please look at the tags before you continue.
Just to be clear... I do not romanticize the abuse, manipulation, or violence in this story. None of what happens here is meant to be desirable or justified. I do ship Charisk as a concept, but not in the context of this story. What you’re reading is intentionally toxic, and that toxicity is the point. I’m still undecided about the ending, but I want to be upfront: Chara may not get redemption, and this story may not have a happy ending at all. Please keep that in mind as you continue.

Summary
As you walked you failed to hear the screams of terror of a bus going over 100 miles per hour and the sounds of it starting to bust down- it speeds near the sidewalk—the people in it shriek. Their blood curling screams didn’t occur to you, your headphone quality being way too good. Your shoulders relaxed as you stretched your limbs; very much unaware of the danger and pain that would very much make your life way more miserable. You should move out the way. But- likewise, you are unaware. Of death flickering and time excited to cut your strings.
The bus is almost out of energy- and has been stopped.
Or so people thought.
It began to tilt- right where you were very much slowly walking. Andddddddddd—
It didn’t crush you to death.

Summary
With the ascension of monsters, there hasn't been a boring day since. Living in a town close to the mountain range had its perks, and things certainly changed when the neighbourhood I lived in starts getting new residents.
The only problem now is finding a better job.
Luckily, a skeleton appears and tells me about a restaurant I can work at. I accept.
And I soon run into a whole bunch of other skeletons that all seem to like me.
Romantically, and I'm afraid of what will happen.
