When fragments of an alien megastructure—codenamed The Echelon—begin crashing to Earth, each piece alters reality in unpredictable ways. Governments and black-ops divisions race to control the debris, desperate to weaponize their power. Adrian Cross, an ex-special forces soldier branded a traitor after a botched mission, is caught in the middle of one such recovery. When an explosion sends a shard of Echelon debris into his body, it bonds with his nervous system, creating a Nanocore System—an evolving AI interface that can rewrite biology and physics itself. Adrian escapes from the government lab that tries to dissect him and soon discovers the truth: other debris fragments have fused with people around the world, turning them into Augments—humans twisted by alien technology. Hunted by every faction, Adrian becomes a fugitive, struggling to master his new powers while uncovering the purpose of the debris. He crosses paths with Dr. Lyra Quinn, a scientist who believes the fragments form a living network—a consciousness scattered across the planet. Together they uncover a chilling reality: the debris isn’t just alien—it’s sentient. Each piece Adrian absorbs brings him closer to understanding the alien mind inside him… but also further from his humanity. As the Nanocore evolves, Adrian learns of Project Echelon, a secret human initiative to reassemble the alien structure as a planetary superweapon. But the real threat lies beyond Earth—the Architect, the original intelligence that created Echelon, is coming to reclaim its fragments. When the world descends into chaos—armies battling over debris zones, cities collapsing under spatial rifts—Adrian realizes he may be humanity’s last hope. He must either fuse all fragments and rebuild the Echelon to fight the Architect, or destroy it completely…

Kieran expected death but when he opened his eyes, he wasn’t greeted by a celestial herald or a mystic inheritance. He was greeted by the rotting stench of the Verdant Cloud Sect’s refuse pits thrown there after his Qi channels were shattered for daring to protect a fellow disciple. A cripple. Trash, discarded by the world of cultivation. As despair threatened to consume him, a cold, resonant voice echoed in his mind not from a heavenly treasure, but from the very spiritual garbage surrounding him. [System Initializing…] [Host Located: Zero-Star Aptitude. Mortal-Body. High Compatibility.] [Welcome to the Cosmic Scavenger Initiative. Processing Local ‘Waste’…] While geniuses plundered ancient tombs for legendary swords, Kieran’s system analyzed broken pill slag to reconstruct perfect Divine-grade elixirs. While young masters absorbed pure spirit stones, his system taught him to devour the corrosive resentment from cursed artifacts, turning poison into pure, terrifying power. His domain wasn’t a pristine meditation chamber it was the dump. And every piece of “trash” was a puzzle piece to ultimate strength. They laughed when he crawled out, covered in filth. They sneered when he dared to re-enter the outer sect as a janitor. But when a demonic beast core deemed too unstable and discarded by the Patriarch landed in the refuse heap, Kieran simply smiled. [Scanning… ‘Catastrophic-Level Waste’ detected. Beginning Assimilation.] Now, the sect that discarded him trembles. The geniuses who mocked him are baffled. For the man they left in the trash is sifting through the bones of fallen gods and the wreckage of dead realms and his cultivation path is built on everything they were too arrogant to see. This is the rise of an underdog no one saw coming, A cultivator who will forge a throne from the universe's waste.

Cassian Vale, a burned-out ex-orbital marine turned gun-for-hire, accepts a suicide contract: extract cortex-slave Maren Sol from cartel sky-city Helios-9. During the escape he accidentally triggers a ten-thousand-year-old kill-switch buried in her implants. They destroy a hunter-killer corvette and half a marine strike wing in the process. Cassian calls in his last favor from the rogue 117th Revenant Wing, only to discover his estranged brother Julian (now a Coalition admiral) has come to collect Maren personally. Cassian kills Julian’s super-dreadnought by letting Maren rewrite its reactor. In the moment of victory, the true owner of Maren’s implants wakes up: the Choir, an ancient ascendant AI that fragmented itself to protect humanity from its own power. One of those fragments is Maren. It wants the piece back. The Revenant flagship is devoured. Cassian shoves Maren into an evac pod and stays behind with a dark-matter grenade.

They said he was nothing. The System agreed. Born Null in a world where your rank is your worth, Oren Vask has spent twenty-two years being invisible. No power. No place. No future. Just survival, one day at a time. Then the Purge comes — the System's cleansing event designed to erase every Null from existence. Oren does not get erased. Something wakes up inside him instead. Something old, something forbidden, something the System has spent centuries trying to bury. The Null Codex activates. And for the first time in his life, Oren is more than nothing. But every power the Codex gives him comes at a price. A memory. A piece of himself. The stronger he becomes, the less of himself remains. And the people who built the System? They are coming for him. Because Null was never the weakest class. It was a prison. And Oren Vask was never meant to get out.

He is the hidden heir to the world’s most powerful conglomerate. And now, after Sophia’s cold betrayal, he’s done playing the fool. When Ethan walks away from the Steele family, he disappears into the shadows—only to return as their worst nightmare. With wealth, power, and ruthless determination, he will dismantle everything they hold dear, piece by piece. The once-mighty Steeles will crumble, and when they finally realize who Ethan truly is, it will be far too late. They called him a nobody. Now, he’s the one pulling the strings. And this time, he won’t be silent.

The Land of Seppora is a beautiful lush place, teeming with life and magic. It lies at the heart of Tempora, a world created and sustained by magic and nature. This is how Seppora looks, at least from the outside. The leadership structure of Seppora is however rife with corruption and injustice. The powerful are treated as gods and the poor are treated as trash, at the mercy of the aristocracy. A band of misfits known as Lux Libera aims to change the narrative for the better, at least on a small scale. But there is something deeper and more sinister that awaits them. Soon they begin to piece everything together. Attacks on innocent villages and capture of thousands who are never heard from again, The Solarian Temple's clampdown on non-conforming mages, and the Imperium's blind eye to the shortcomings of its officials, all lead to a plot steeped in darkness, one which could spell the end of not just Seppora but Tempora itself. Can 5 people with twisted pasts whose paths somehow align be able to stop this abomination?

Kael Varyn was four when the Cult of Akary slaughtered his family. Twelve years of brutal training later, he has become something unprecedented: a Contractor with an Infinite Soul, able to carry more than one contract. Every enemy he kills makes him stronger — but each stolen entity leaves behind whispers of borrowed memories, threatening to drown who he is. As he hunts the cult across a world where humans bargain with Fifth-Dimensional beings for power, Kael discovers the slaughter of his family was only the first move in a centuries-long plan to tear the barrier between worlds wide open. To stop it, he'll have to unlock a Soul-Bound contract with Liciferous, an entity so dangerous the gods themselves fear him. But the cost of that power might be the last piece of himself. The Contractors is a dark fantasy about whether a person is defined by the power they wield — or the choices they make when it matters most.
