O Negative by BCMetcalf

Content Warning-This story is meant for mature audiences. It features adult language, references, situations, sexual content, graphic violence, and gore. Fantasy, horror, and science fiction are my favorite genres to read. They are also my favorite to write. I've enjoyed writing since I won my first writing contest in the fourth grade. That was over twenty-five years ago and I haven't shared a sinlge word of it. Imposter syndrome is a bitch! Well, I finally managed to pull the trigger. Here is "O Negative". It's a mix of all of my favorite genres. I've mixed a fantasy, based on present-day Earth, with plenty of graphic horror and wrapped it all up within a world driven by the technological advancements that only can be obtained from millions of years of civilation. A small group of strangers find themselves surviving in a decimated world. It's bad enough to be stranded in a no-name town, but things become surreal when you realize the vast majority of humanity has died...it becomes terrifying when you realize you aren't that lucky to be alive. "Survivor's Guilt" isn't a thing when you find yourself the sole food source for an entire group of beings that no longer need to hide in the shadows. Man is no longer at the top of the food chain...they are now the cattle.

Mayhem 2019 (JackSepticEye Prompts) by ninjago4lyfe

A list of prompts by @septic-bella on tumblr for May! It's in honor of the chaos in May 2018 on JackSepticEye's Youtube channel, but it's technically free-for-all in any art form (I might draw some stuff and post the pictures as chapters instead of writing prompts). I started late, but I can catch up quick probably, so let's do this! Here's the prompt list, for my sanity and for any of you to follow along! Day 1: Into the madness Day 2: Lost Day 3: The calm Day 4: The Doctor Is Back Day 5: Stories untold Day 6: He's Listening Day 7: Gone silent Day: 8: Connected Day 9: Try To Fall Asleep Day 10: The end is near Day 11: Tie Day 12: Winning Day 13: Alcohol Day 14: Dark Silence Day 15: Abandoned and exiled Day 16: A way out Day 17: Father Day 18: Childhood Day 19: Journal Day 20: Infected Day 21: Trash Day 22: Cold Day 23: Champion Day 24: Clues Day 25: Terror Day 26: Actor Day 27: Going crazy Day 28: Ruined life Day 29: Ending Day 30: Left alone Day 31: Mayhem Edit: It has been finished!!! I accidentally connected stories that shouldn't have been and took longer than the allotted time frame to do it. I also didn't draw anything, it's all written. TRIGGER WARINGS IN THE TAGS!

SmackDown: Back to Our Roots by LayethTheSmackDown

Our previous two SmackDowns were both massive successes, and it's high time for another. You might remember the last one was heavy on the "game" elements, maybe even too heavy. This time we're going back to the basics and keeping it simple. It's just a motherfuckin' sci-fi SmackDown: a heated writing contest where contestants are given text-, music- and visual-based prompts, and then they need to write a short story around that, following which they're judged for their efforts and either move on to the next round or they get eliminated from the competition. But there's gotta be some kind of twist, right? For this one we're waxing nostalgic, we're looking back into our past. We're going back to our roots.

Melini by Saurna

A collection of short stories which are segments of the one story I want to write. I'll add more later once I flesh out the segments. The chapters are somewhat in chronological order. Some stories overlap in their timeline because the endings are different, but they belong to the same segment of the story. It's got aliens, gods, soulmates, wars, reincarnation, time-travelling, prehistoric elements, Historical events, futuristic themes.

04Lonewolf's Short Stories by 04Lonewolf

[WARNING: Please do not copy any of these without permission! If you see someone else using these ideas, please let me know, because these are all my own work.] This book is basically just a compilation of all my short stories that I've written over the last couple of years. Story titles with '🏷️' are inspired by a short story prompt or other literary work, whilst ones with '📙' are stories purely from my own imagination. Ones with '🧩' may be an excerpt from a larger story I'm working on, but can still be considered as a short story by itself. Also just letting you know in advance that I wrote quite a few of these when I was younger and they are really bad 😅. Well, even my recent ones aren't the best. All I'm saying is... these are my very rough drafts, so read at your own risk, and please be positive or feel free to (politely) point out any mistakes so I can make them better :) Enjoy! [DISCLAIMER: I do not own the story cover background, credit goes to the original owner]

We Dream In Ones and Zeros: An Anthology by MPRCunha

❝ We are the ones who dream in ones and zeros. Do you dare to dream with us? What will you see? Will you like what you see? Or will these dreams turn into nightmares? ❞ A collection of short stories in the science-fiction genre, but with a twist. If you're looking for sci-fi stories told from a different perspective and with a more personal, emotional, intimate touch, then this is the collection for you! If you don't know where to start, then check the synopsis chapter for a brief and (mostly) spoiler-free description of each short story in this collection.

SPOREFALL | ONC 2025 by AwgawinFiresnap

Three months ago, a thick, white powder covered the Earth overnight. Not snow, but spores, hundreds of spores, all from an unknown source. Those that came into contact with the substance became spore-touched: violent, uncaring, every one able to turn into plants hundreds of feet tall and rip apart the world itself. Three months ago, Mya lost her humanity, and with it, everything she knew. Not all at once, but every day is another memory gone, all washed over by new instincts, identities, and wants. In a city slowly being torn apart by the massive vegetation of her new kind, her options either to join their collective, or escape with what remains of herself, her days are spent surviving, and hiding amongst Humans. Humans that will burn her alive the second she's caught. The only thing she has is a water bottle and the goals of her former self, but the likelihood of achieving them in a post-apocalyptic world is bleak enough, and that's if she can still remember them by the end of the week. So when another spore-touched offers to take her to a supposed safe haven, all with the hope that they both can be turned back, she takes it. Not because this new companion seems like the most trustworthy person, not because they can promise to stop her from becoming a monster- She takes it because there's nothing else to choose. ONC Entry for 2025. Prompts used: 68., 103., and perhaps a little of 134.
