Summary
This is a science-fiction pastiche braided from Moby-Dick, Frankenstein, Norse saga, scripture, and orbital mechanics—a story about obsession, parenthood, survival, and the unbearable cost of naming something yours. As asteroids are hunted and histories collide, the line between hunter and hunted erodes, leaving only the question that echoes through every vacuum:
What does a creator owe what lives after them?

Summary
The war with the All for One ended and Izuku was allowed to rest, using the remaining energy of the One For All to save some more people, finish school and then move over to another profession that allowed him to help people, while enjoying the fame of being at the forefront of saving the world. And thus ends his story.
....
Yeah, right. No way it would be so easy. Instead of enjoying his early retirement from the peak of heroics, he ends up waking up as some sort of biomechanical facsimile of a person in the distant future. And it's not even the distant future of his own world, but of some sort of alternative timeline? And in space? With his first acquaintance in this foreign world being a psychopathic AI who considers AM and Skynet to be their role models?
So much about retirement.

Summary
Fire Alone Can Save Our Planet...
For generations, four planets of an alien race of cats have shared the solar system according to the laws laid down by their ancestors. But the Thunder Fleet cats are in grave danger, and the sinister Shadow Fleet grows stronger every day. Noble soldiers are dying - and some deaths are more mysterious than others.
In the midst of this turmoil appears an ordinary working cat named Rusty... who may turn out to be the bravest pilot of them all.---
A sci-fi retelling of the Warrior Cats series. A very simple beat-for-beat retelling but with all the characters as an anthro species of cat living in a futuristic space setting. Plot rewriting will be minimal.
Updates by chapter as I find time. This is a project for myself while I recover from surgery.

Summary
After a Universe Engine session's victory door was destroyed at the final moment, its players have scattered to the cosmic winds.
Centuries later, Harbinger Lyra Sonoshe, Witch of Time, has abandoned the Extracosmic Witchkind Legion. Her former sessionmate and subordinate, Galaxy-Weaver (Orgalaxy, but please don't call her that) Rafkel Argyro, Sylph of Blood, stays behind, alone, to pick up the pieces and covertly play interference to keep the EWL off her lover's trail.
Then the first death after the end of the session hits. Rafkel decides she will stop at nothing to mend the bonds of her shattered session and fix things with the few estranged loved ones she has left.
She decides the only place to start healing is by arranging to drug Lyra and Uselah Olceta, the deicidal terrorist who destroyed the door to their new universe, with empathogens, and force them into a room together.
The only problem is that nobody is willing to talk to each other, least of all the two of them. A massive intercosmic conspiracy unfolds as Rafkel schemes and abuses her rank to reconnect with old friends and enemies, all with the goal of making those two understand each other, whether they want to or not.

Summary
Jeongin has always known he’ll be married to an offworlder and end up settled far away from home. Sedaora Selene I is nothing like his own planet, with its lush jungles and warm climate. A moon orbiting a gas giant, the homeworld of his new fiance is cold and grey and worships a god with no face, its surface covered by a black, choppy ocean that never settles. Selene I’s grim and strange reputation far precedes it, but Jeongin has gotten no other offers and no longer has a choice. At least Prince Chan seems kind, and is near enough to Jeongin in age.
Minho has been betrothed to the omega son of his father’s closest advisor, Felix, since he was eight and Felix was merely five. As the only child of the Dityodos, expectation and duty weighs as heavily on Minho as his crown. He and Felix are the darlings of Selene I, a match blessed by the Maker himself. With his cousin, Chan, now finally betrothed and soon to be wed, it will not be long before Minho, too, is expected to make good on the promise his father made sixteen years ago.
And then Chan comes back with his new intended in tow, sun-kissed and vibrant. Jeongin is a perfect match for Chan in every way. But that does not stop Minho's head from turning.

“Ew. Don’t touch me.”
“She moved. She definitely moved.”
“Oh you’re definitely losing it,” Jax teases through a chuckle. “I’ve seen roadkill less dead than that thing. How much you think we could get for that headset thingy she’s hooked up to?”

Summary
So Steve didn't complain once. He said nothing about the awful canned food or the bad coffee, about Dr. Buckley's singing in the showers or the smell of Sinclair and Munson when they come up from the engine room. He didn't tell the captain how unfair it was to bunk him with Mike Wheeler and Will Byers, two literal boys who were sharing his cabin, and when finally Steve couldn't take anymore of their giggling and whispering to each other all night long like fucking teenagers oh my fucking Stars — he just took a deep breath.
All day long, Steve was practicing breathing exercises, and repeating calming mantras to himself, in hope that his efforts were gonna be at least appreciated.
And yet, nobody was fucking nice to him.
-------
Steve Harrington tries to embrace his new job as a navigator on the ST Kite, a scout-class spaceship. But just before he arrived, a tragedy struck the crew, leaving them in mourning. The chief engineer, Eddie Munson, is especially hard to work with, and is often very loud about how Steve doesn't have what it takes to be a real spacer. The fact that the guy is also hot doesn't help Steve's situation at all.
