Kill Em with Kindness

by bones_of_a_rabbit

You're not cut out for this. You're sensitive and scared, jumpy and skittish, easily confused and very guillible, anxious and tense. In short, you're a pansy. In your own eyes, anyway. You just want to get out of here. You're not cut out for this place, not when it was calm, especially not now that it's riddled with humans and monsters constantly at war with one another. You just want to stay safe until you can get out of here, want to keep your hands out of this mess until freedom makes itself known. But then you bear witness to a group of monsters doing something they probably shouldn't, and you're dragged into the fray. You can't bring yourself to be angry or rude; you just want everyone to be happy. ...Especially that skeleton. The short one, who happens to like bad jokes. He deserves it. Also your cat. He also deserves to be happy. ((cancelled))

Forward men of Wesnoth

by Zaravan

'The player congratulated himself on the completion of another scenario. It took a lot of quickloading, but he'd managed to keep all his men alive.''He took a sip of his lemonade as the next scenario loaded, it was taking a while.''When it finished, the first thing his screen showed was a patch of golden flowers. A familiar patch of golden flowers.''He choked on his lemonade, and began to cough until his eyes blurred with tears.'This was not supposed to happen.

Ebott after humans discovered and exterminated her parents.Morgan was a clone given life to fill the needs of an elderly mad scientist and his grandson, left abandoned and on the search for her "father".Nothing they had in common and nothing to unite the two stories, save for one common denominator: a little demon named Bendy.

Eternal Sunsets

by orphan_account

Raven, on a birthday excursion, tripped over a root that sent her into a world unlike any she could have thought of. Scattered with stars that somehow made her immortal, she traversed her way through the Underground and finally made it to the end. After months of attempted friendship, shenanigans, and loads of death, Raven finally broke the barrier and stepped foot on the surface- Only to be shot back down the hole she first fell from and back into the Underground. Confused and with only Flowey to guide her through again, she finally made it to the surface. It's like deja vu, innit? ( Angsty midnight ramblings. With added plot! )

Oddballs and Scarred Palms

by bones_of_a_rabbit

You're the oddball of the group. At least, of the group you're in. You're 'eccentric.' You're 'air-headed.' You're 'out of it.' You're 'a bit of a nut.' You're most certainly not the kind of person designed to be in this profession. You most certainly weren't planning on it, either. But they don't need to know that. Your reasons are your own. You stick to your work, the worst that can happen is you get a little hurt. So what?So what happens when you have to share your work with someone far, far more experienced? And which is worse, the fact that he's showing you up, or the fact that you feel... something for him? What the fuck even is something? And why does it make you feel more out of it then usual? Fuck feelings.

Of Scales and Piano Keys

by bones_of_a_rabbit

He was a man of few words. You weren't. He was calm and mellow. You were bubbly and spontaneous. He was curious. You were, too. It starts when you become a regular that doesn't buy anything. It picks up when Sans befriends you. It becomes confusing when he starts feeling for you. It becomes complicated when you say you're done with love. It gets worse when you start feeling for him, too. Also there's a snake. And a piano.((No real plot, tbh. Just a series of events mainly from Grillby's point of view.))
