Summary
Bree Simmons is a twin.
Her mother had a choice when she and her brother were born. Her choice was to either get floated and let both of her kids flourish freely on the Ark or to give one child up to save another. She selfishly chose the latter.
When Bree was eight, she realized her mother wasn't gonna come back for her. That she was gonna be stuck in a cage for the rest of her life. When Bree was ten, she learned what was going to happen when she turned eighteen. That she would get floated for being born.
When Bree turned thirteen, she started her first fist fight and earned two weeks in solitary confinement. She was fourteen by the time she had her second fight. That was when she learned what she was. Nothing but a freak with black blood. At fifteen, it was her third and final fight in the Sky Box. This bought her a permanent residency in solitary confinement.
Just days before her eighteenth birthday, Bree finds herself on a drop-ship to Earth.
What will happen when she meets the Commander of the Twelve Clans?

Summary
Ariella Coyn was born in space, and she's lived there her whole life. She's been a prisoner on the Ark since she was 11 for a crime she didn't commit. Now a year later all 100 juvenile criminals are being sent to the ground and she's the youngest among them.
She's shy, quiet, and keeps to herself at first as she doesn't know anyone, but once she gets to talking to Bellamy Blake, the stowaway who committed a heinous crime to protect his sister, and Jasper Jordan the geek with the goggles she starts to come out of her shell a little more.
The 100 are forced to build a camp from the ground up with no help from any adults. Tensions build as drama breaks out among the teens over who is in charge but that's the least of their worries as they soon realize they're not alone on the radiation-soaked planet known as Earth.

Summary
Three months after the massacre at Mount Weather, Clarke Griffin is no longer just a survivor—she’s Wanheda, the death-bringer. Hunted, haunted, and hiding in the woods, she’s finally captured and brought to Polis, where Commander Lexa—her former ally and betrayer—offers her an impossible choice: help Skaikru join the Coalition as the 13th clan, or watch everything fall apart. Clarke is forced into the heart of Grounder politics, where allies are scarce, enemies wear crowns, and every gesture is a negotiation. Lexa, burdened by guilt and ruled by duty, begins to unravel her feelings. Amid secret meetings, rising tensions, and the looming threat of Ice Nation, Clarke and Lexa find themselves on opposite sides of a fragile peace—and an undeniable pull. In a world where love is weakness, can they risk everything to save their people... and each other?

Summary
In Arabis's "Schism", The Autobots successfully manage to incapacitate Megatron in Nevada, but their victory is short lived when an unidentified Scorpion approaches and opens fire. MECH is responsible.
Except in this AU, SCORPIA is falsely accused. As the criminal syndicate's new director, the Yassen Gregorovich risks a meeting with The Autobots to clear its name. Unbeknownst to both factions, this leads to an unprecedented series of events that leaves Earth hanging in the balance when the world’s most dangerous weapon falls into the wrong hands.
-
This is an alternate universe within the "Arcane" series, set after the Nevada battle in "Schism". I took the liberty of mashing together a few of my favorite fandoms and somehow made it work. Not beta'ed and just written for fun. Enjoy!

Summary
In a fractured timeline where it all began, a newspark's awakening will ignite a war no one is ready for.
Across the ocean, the Autobots are unraveling. It’s been a year since Sam Witwicky vanished after a Decepticon attack, and every trace of his spark signature has gone dark. When a new anomaly flashes across their sensors, it’s not him—but it’s something new. Someone alive.
As the Autobots race to uncover the origin of this mysterious signal, Madi is reborn in silence—stripped of her past, yet carrying within her the key to stopping the future from repeating what it’s already becoming. And unbeknownst to all, factions from Earth’s shadow governments and Cybertron’s buried past are already closing in.
Alliances will be tested. Enemies will become allies.
And from the ashes, a new kind of Commander will rise.

Heda Lexa kom Trikru, the Creator of the Coalition by Aithusa_DiAngelo
Fandoms: The 100 (TV), The 100 Series - Kass Morgan
24 Oct 2023
Tags
Summary
300 years A.P. (After Praimfaya), after suffering for 5 years under Heda Malachi, or Sheidheda, as he was nowadays called, Lexa kom Trikru has a vision.
She will not kill her brothers and sisters, she will not allow her people to be afraid anymore.
No more Conclaves, no more Sheidheda.
This story starts 297 years after the Nuclear Apocalypse, as opposed to the 97 years of the show. This is mostly because 97 years is not nearly enough time for a culture as complex as that of the Grounder's to develop.
The Ark has been told that the ground would be survivable after 400 years, instead of the 200 years of the show. This is mostly, again, to give time for the Grounder culture to develop.
The Grounders have set as year 0 the year of the Nuclear Apocalypse, aka. Praimfaya.
There are more people on the Ground and in the Twelve Clans, the same is true for the Ark, but there is, like, 1 person more for the Ark for every 100 in the ground.
The Flokru do not exist. In my understanding, the Flokru were created by Luna after she fled the Conclave. She never did that here, so the Flokru have been replaced with Okenadon, the Ocean Clan.
Sheidheda is the Heda before Lexa.

Summary
{word count is a horrendous lie.} A whole new adventure based on the world suggested by ProphecyGirl's story The Walking Dead: Brave New Girl. In 2043, Becca Franco killed the planet. The world has since been restored from the ashes, but it looks nothing as it once did. Separated by large ranges of radioactive, walker-filled wastelands are dozens of individual factions; each of them with their own methods of surviving. Each with their own offerings and needs.
Some people live a natural, nomadic lifestyle like the relatively unorganized indigenous Sangedakru. Some found their place amongst the self-appointed environmentalist group, the so-called "Guardians of the Sea", Floukru; who maintain the only functional oil pipeline, the Deepwater Horizon, in the Gulf of Mexico. Many bowed to the harsh ways of the industrialized Saviors, who control the oil refinery and aren't too happy about the limits Floukru places on their imports. War brews throughout North America between the three most powerful factions in the world, who also suddenly find themselves facing down the end of the world. Again.

Summary
Anya is captured within the Mountain when she sees a princess. She knows nothing about her yet, just that she has nightblood and that she is of no known clan. She discovers that only the Mountain Men live under the earth's surface.
The story starts in season 2 shortly before Anya and Clarke escape the Mountain together. It will follow the series, but there will be changes as well. Recommendations for improvements are highly valued.

Summary
Getting to space on a hundred year old rocket was always a long shot plan. But maybe that wasn't such a bad thing.
5 years alone on a planet doesn't sound that bad if they can actually find a way to survive. Maybe they'll finally get a chance at a peaceful life.

That's what he told her.
Together.
They did things together. Not apart. Together. He couldn't leave her. He wouldn't leave her... Even if he died, he wouldn't leave her. At least if he died, he'd be with her.
