Edwin Lunar

Living on the outskirts of the futuristic city of Vestella, Edwin survives by repairing broken machines and forgotten technology while carrying the pain of losing his parents at a young age. The only things left behind by them are a mysterious silver ring and an old scarf — relics from a past Edwin barely remembers. But everything changes when a hidden organization discovers him. Taken to the legendary moon-world of Noroel, Edwin enters the secretive Lunar Dominion Academy, a massive fortress where gifted children are trained to become elite warriors capable of controlling the power of the Eternal Flame — an ancient energy source that powers entire civilizations. As Edwin struggles to adapt to the dangerous academy life, he forms unexpected friendships with the intelligent Iris and the loyal Carl while facing powerful rivals, brutal training, and mysteries buried deep beneath the academy walls. Yet strange things begin happening around him. Systems malfunction in his presence. Ancient machines react to his father’s ring. And voices hidden inside forbidden networks begin calling his name. Soon Edwin uncovers the terrifying truth about Groader — a former academy prodigy whose obsession with the Eternal Flame nearly destroyed Noroel years ago. Though officially dead, rumors claim Groader’s consciousness still survives somewhere within hidden systems beneath the academy. When a sealed underground sector known as Sector Zero suddenly awakens after twelve years of silence, Edwin realizes his connection to Noroel runs far deeper than anyone imagined. And the truth about his parents’ deaths may change the future of the entire system forever.

Allen Voss is a master of steel, a 17-year-old social recluse who has 100% completed every mech-pilot sim on Earth . For him, life is simple: gears make sense, people don’t.

Yet, the digital ghosts of his parents’ past aren't his only complication. By his side stands Seraphine, a high-ranking Marquis of the realm whose aristocratic steel and unwavering loyalty force Allen to face the weight of his new crown . While she shields him from the judgment of the living, Allen remains haunted by the girl he left in the real world—Ciara, desperately fighting her way into the game. Between a calculating AI Architect, a corporate conspiracy, and a noblewoman who refuses to let him apologize for his nature, Allen must survive in this new world that is shaping around him. From the grave to the stars, Allen will take it all for himself.

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.
