Mortal Protection Services

The Earth wakes up to find itself surrounded by completely different stars. An announcement rings out across the planet: "We at Mortal Protection Services have relocated you to a foster system temporarily. Do not panic." . . Some of you are panicking, when we specifically asked you not to. What to expect: Sci-fi: Various densities, mostly soft. We got your warp drives and subspace enfuckulators, but also a touch of hard space reality. Who doesn't love a chewy candy with a hard shell? Comedy: From slapstick to erudite to troglodyte. We got stuff for any brow level you want. As well as many, many easter-eggs for sci-fi & fantasy nerds alike. Galactic horror: I'll leave the fully fleshy nature of that for you to discover a few chapters in, it's better that way. Fun with Letters: Silly little anagrams, and silly little acronyms. A Hyperspace Cat. (Proudly made by humans. No AI in Writing or Art. Cover by Instagram user: pedro_serpa_75)

Ten Thousand Fleets

Arc Sandhurst will become a mech pilot, even if it kills him. After his sister's ship is attacked by the Pirate Queen of Nepenthe with all hands lost, Arc enters the Imperial Mech Academy on the deathworld Vidako in order to get revenge. The academy is the only place that the son of a silk-worker can get the enhancements that are required to pilot a mech - but first, Arc will have to survive disagreeable roommates, hazing from upperclassmen, the friendship of an imperial princess, and the steaming jungles of Vidako. Regardless of what Arc wants, the Imperium Stellarum will need every good pilot it can get - because empires are built on a foundation of blood, and the sins of the first emperors are about to come due. Lost fleets lurk on the edge of known space; the ruins of ancient races are spread across long-dead worlds; and enemies thought defeated gather their strength once again. War is coming to the Imperium. What to Expect: An intelligent but imperfect MC who progresses in capability and rank over the course of the series. Think the story arc of a Richard Sharpe, Horatio Hornblower, or Honor Harrington. MC will begin as a 4th class cadet and climb the ranks, gaining more autonomy and political power as the years pass. If you want to watch someone climb from cadet to admiral, this is the story for you. Progression elements include genetic modifications, cybernetic implants, humans paired with AI partners, and, of course, upgrading and customizing mechs through battlefield salvage and cutting edge tech. The mech bits are where you'll find the crunch - expect lots of models, variants, and weapon loadouts. Multiple POVs will offer a view of what supporting characters and antagonists are up to, but the focus (and majority of the chapters) will always remain on Arc. The first volume is roughly 80% MC, 20% other POVs, with most of those being the deuteragonist. Power Couple: All characters are over the age of 18, and begin in a military academy environment designed to produce officers. It is my intent to build a relationship into the power couple trope, but expect political foolery and arranged marriage complications along the way, and keep in mind that the characters have to navigate the rules of serving in the Imperial Fleet. HFY: Humanity, and the Imperium Stellarum, are at their core a force for good in the universe. They are flawed, but trying to do the right thing and are in many ways exceptional / aspirational. Four alien species have joined the Imperium because they want to be part of what humanity is building, and see its potential. Slow Burn with character development, politics, conspiracies, and secrets which lead to brutal action. I intend to do at least a volume for each of the four years at the academy, and then a volume each per rank. If things follow the plan I've sketched out, expect 13+ volumes. Inspirations include Battletech, Gundam, Dune, Babylon 5, and Twilight Imperium, among others. Content Warnings: Graphic Violence - This story will feature science fiction battles with mechs as a primary element. Expect people, animals, and places to be lit on fire with enormous flamethrowers, cut in half with plasma swords, crushed under enormous metal feet, and otherwise dismembered. Profanity - The characters in this story are actively serving combat personnel. They will swear. Sensitive Content - Soldiers get PTSD. Alcohol and drugs exist in the universe. Some of those in power abuse their position to traffic or take advantage of those without power. Bad guys do bad guy things. Update Schedule: Five chapters a week, M-F. Any vacations will be announced in advance. Cover by Sarah Murphy. Mech Art by Victor Yañez. There is no use of AI, in any way, in this work. I use em-dashes because I like them, particularly when trying to create dialogue that starts and stops in the way people actually talk. This story is posted on Royal Road, Novelpedia, and my Patreon. If you find it anywhere else, it's been stolen.

LOST

LOST Some places are almost the same. Some choices are not. When Sai arrives in the quiet coastal town of Misakiura, he expects nothing more than a brief escape from his ordinary life. Instead, he finds a town wrapped in silence, strange coincidences, and people who seem to know far more than they should. Small inconsistencies begin to appear. A familiar street feels unfamiliar. Memories no longer agree with reality. And every answer only leads to another impossible question. As Sai uncovers fragments of a hidden truth buried beneath the town, he realizes Misakiura is connected to something far beyond imagination—a mystery that challenges everything he knows about identity, memory, and the meaning of home. Some worlds are almost identical. Some choices change everything. And sometimes... getting lost is the only way to find where you truly belong.

THE FIRST CRADLE - BOOK ONE OF THE IRON CRADLE SAGA

The Sun is dying, and there's no saving this world. Engineering grad student Gavin Daniels volunteers for experimental brain emulation technology--humanity's last chance to gain centuries of research time while only days pass on Earth. But the untested cradle connects him to something ancient: a galaxy-spanning competition called the Ascendancy, where Earth's survival is the prize. The rules are brutal. Earth is unrecognized, unprotected, and legally open for conquest. Win, and the planet gains galactic protection. Every victory captures alien technology to fuel humanity's desperate evacuation. Lose, and everything is forfeit. In a genre built on solo heroes grinding for power, Gavin and Earth's champions choose a different path: reincarnating the souls of Earth's dead as spirit-born warriors, building armies instead of going it alone, forging alliances with alien species, and refusing to treat war as a game. But those overseeing the Ascendancy aren't safeguarding peace--they're filtering threats. Culling potential rivals before they can rise. Can Earth's champions survive alien dinosaurs, and a universe that seems to want to crush them? Our only allies, a race that died on Earth before humanity ever took its first steps... Step into the cradle, champion, and find out. THE FIRST CRADLE - THE SECOND CRADLE - A LITRPG ADVENTURE

Children of the Meteorite

Twenty years have passed since the Great Collapse, and the world has been reclaimed by nature — but not the nature we once knew. Colossal trees and mutated vegetation now dominate the landscape, and humanity's only weapon against the monsters that roam the wildland, are poisonous crystals found deep inside the infested forest. When the crystal hunter Rosario and her young apprentices Stefan and Franziska accidentally discover a swarm of monsters threatening to overrun a nearby settlement, their attempt to warn the town will inadvertently uncover a conspiracy that stems from the origin of the Collapse itself.

Echoes of the Silent Sky

Year 2147. The Sun stops—not dead, not dimmed, but *paused*. Fusion ceases for 11 minutes and 43 seconds every 72 hours. A silence with a pattern. A signal. Astrophysicist Dr. Ella Vayne decodes the sun's tremors and discovers the frequency matches human brain theta waves. Not coincidence. Something is broadcasting to Earth—or waking something *in* Earth. Recruited into a black-ops mission, Ella and ex-special forces operative Kasen Reed are sent to a remote Martian research base. The scientists there report footsteps in the dead of the base—footsteps that echo from 300 meters below, where satellite scans show only empty rock. What they find buried beneath Mars isn't a ship. It's a **memory vessel**—a relic built by a civilization that encoded its final moments into a structure that responds to human neural patterns. And Ella's brainwaves? They sync perfectly with the sun's silence. They always have. She wasn't chosen. She was *made* for this. But someone on Earth is building a tower—a transmitter. They don't want to receive the signal. They want to **reply**. The question isn't who sent the silence. It's who—or what—will answer back.

Not Quite Star Trek

A Man rides an experimental space ship engine that pushes him close to the speed of light, knowing he'll miss out on two hundred years before he returns to normal time. Turns out they invented warp drive like a week later, but he had become too valuable as a tourist attraction to pull him out of near light speed travel, so they just... didn't stop him until the ship stopped itself. He finds the future he arrives in not at all to his liking, so he goes for another round... and another... and another. Will he ever find the star trek future he's looking for? Or will he just meet strange new alien races, and try to bang them.

Gematrail — Echo Observer — Lævateinn

There is a layer to this story that cannot be reached through the surface plot alone. Clues have been deliberately woven throughout the story for the author and readers to uncover together. Everything needed to reach it should already exist in the knowledge and tools we possess, yet it has not fallen into anyone’s hands—not yet. As you read on, the story quietly waits for someone to notice. *** DEVOUR. The ordinary. The reality. The world. Despair, hope, good and evil—none are permitted. The prophecy is fulfilled here. Soon, the world will lose everything. And the man who once saved it has already lost himself. *** The boundary between illusion and reality had long since ceased to exist. In the year 20XX, without warning or precedent, Monsters emerged — consuming cities, devouring lives, swallowing the world’s last reserves of hope whole. And then, when humanity had nearly surrendered to despair, a Savior appeared. What awaited him was a death sentence — the charge: high treason against the state. Stripped of everything that had ever made him himself, he was cast into a cold and indifferent sea. Yet even there, sinking through the abyss, a light found him — the luminance of a Goddess, merging with what remained of his shattered soul. Darkness coiled around him like a living thing, its tendrils hungry and absolute. And still, against all reason, he was pulled back to the surface. He returned with nothing. No past. No name. No self. They gave him a new one — Ariwara Yūki — and with it, a second life stitched together from silence and borrowed time. Beside him walked Sano Amana, the girl who would become his anchor, and for a while, the two of them knew something that almost resembled ordinary days. Then the Monsters came back. They always come back. As his own memories continue to bleed away, Yūki pursues the vanishing silhouette of Amana — drawn ever deeper into a storm where government conspiracies and the ambitions of shadowed factions grind against each other like tectonic plates. He was once the Savior of this world. Now he has nothing. So what, exactly, can a man with nothing left — do? *** Comedy / Ecchi / Fantasy / Harem / Horror / Mature / Mystery / Romance / School Life / Sci-fi / Slice of Life / Supernatural / Tragedy From Japanese Full-length light novel This translation is provided by the author.
