Summary
The terminal monitor swings, filling Shadowheart's vision with the gentle chyron of Mother Mainframe. Upon the screen she is two perfect lips and a gaze covered by a fluffy eyemask. There’s a fetching pair of eyes embroidered upon its silk: lined dark, full-lashed and painted deep purple. They stare out with a knowing gaze while Mother, ever-working through each vein of their Vault, slumbers softly beneath.
The face soon fades. For a moment, she is alone in the false moonlight of the medbay, before the ominous tick-tack of text spills out in stark green.
>Hello, citizen SHADOWHEART. Welcome to your Vault-Tech Certified Check-Up! Don't recall the last one? Congratulations– it worked!

Summary
Gladys wasn’t made for this. Gladys wasn’t made for any of this. She was just a technical writer for Vault-Tec who barely had experience holding a gun. But when she emerged from Vault 111 after 200 years in cryo-sleep, she found herself making choices she never thought she would have to make.

Summary
A realidade das Vaults era um luxo, lidar com a radiação e com o mundo lá fora não era o que as pessoas estavam querendo para a sua vida, muitas se viravam como podiam, Eren aprendeu desde cedo que ser um caçador de recompensa poderia compensar bem mais para sua sobrevivência.
Mikasa, por outro lado, vinha de uma Vault esquisita até mesmo para os padrões das demais. A vault 123 era completamente fora da realidade. Tinham um sistema próprio e lidavam com tudo de uma maneira que parecia sair de um conto de terror psicológico.
Seus caminhos acabaram se cruzando quando Eren recebeu uma proposta tentadora: dez mil caps pelo sequestro de Mikasa Arckerman com vida.- Language:

No Place Like Home by Thunderstorm_of_Destruction94

Summary
Before the bombs fell, Katherine Witherspoon was a nurse living a fairly ordinary suburban life with her husband and son. That all changed one October day when someone pressed The Red Button and the entire world came to a screeching halt. Now, 200 years displaced, she has to learn how to live in a world where all the rules have changed. When the wasteland has chewed her up and spit her out, can she learn to forgive the very people that hurt her the most?
A story you know, with a few new elements twisted in. A reimagining of the Fallout 4 storyline, told through the eyes of a woman just trying to pull her life back together. A slow burn, Kat starts to learn that Home isn’t the place, but the people you have in your corner.
I tried to write this in such a way that it could be enjoyed by anyone—even if they don’t have any experience with the Fallout series. If you like grounded, character-driven, post-apocalyptic stories with some mild sci-fi elements, I think you’ll find something you like.

Summary
In most universes, the Gates opened in low orbit above Pluto, others to their equivalent, leading to a shared dimension connecting all of them together. For the worst, as it would seem, as the Imperium of Man uses this new beachhead to launch invasions into every sci-fi and fantasy universe one could imagine.
Welcome to the Janus Chronicles. Where we will explore ever possibility that comes with this premise. And if you have any suggestions on what crossover event should happen, or what characters should meet, please let me know, and I will see if I can incorporate your idea into the story.

Summary
For Falloutober (which I found on Tumblr) this year I wrote short clips of my stories, these stories are not in cannon order and include my own OCs + my own takes of cannon characters! I posted these originally to my Tumblr and then to my Toyhouse, but I thought it good to put here! Sorry if things are messed up, I have never used this site before
PLEASE NOTE: I have included Images with these writings, the characters in this are written as humans but drawn as cats in such images. This is because I dislike drawing people and would rather not draw 31 different things with them

Summary
In 2280, Obi-Wan is just another person who has been kidnapped and enslaved in post-nuclear-war Las Vegas. His life is awful and he just wants it to end. He can’t give up though, not when the Casino Boss has control over his little brother, Anakin.
Time is running out for Obi-Wan and Anakin, and just as everything is about to get so much worse, good luck strikes. Two men walk in who can’t keep their eyes off Obi-Wan and promise to do what they can to free Obi-Wan’s brother. But their help comes with a cost: Obi-Wan needs to help them take down the rich, powerful men enslaving him. Obi-Wan isn’t afraid to lose his life for a good cause, he just didn’t count on giving his heart, mind and body to these men along the way.
Or, the post-Nuclear apocalypse AU where Cody and Rex are trying to be the best of men, yet they can’t quite keep their hands off a very vulnerable Obi-Wan.
(Loosely based on the world of Fallout, you do not have to know anything about Fallout to understand this fic.)
