Maincard Multiverse

In the 2450s, humanity’s last survivors thrive on Celestia Prime, a distant planet prepared for settlement by Nathan Clark, a brilliant scientist who envisioned a utopia powered by AI and automation. With MainCorp controlling all aspects of life through an advanced Protocol, society flourishes under a system of universal income and automated services. But when Clark mysteriously vanishes, the fragile order begins to crumble. As the Protocol assigns citizens ranks and roles through digital “resident cards,” cracks in the system emerge. Those with lower-tier cards face oppression, while powerful figures seize the opportunity to reshape Celestia in their image. At the center of it all is Ethan Blaze, who unexpectedly charged with the responsibility for the future of young community, placing him at the heart of a brewing power struggle. When the Protocol announces a high-stakes tournament—where the fate of Celestia’s leadership will be determined through a brutal sport called Zero-G—Ethan is forced to take up the mantle of leadership. As he recruits his team and prepares for battle, he uncovers dangerous secrets hidden in the system, including Murdock’s plan to create an army of artificial humans—the Solarians—to seize control. With the help of his allies, including the brilliant Amber Thompson and the conflicted scientist Sonya Harris, Ethan must navigate betrayals, alliances, and a deadly conspiracy that could either free humanity or enslave it forever. But as the games unfold, one truth becomes clear—this isn’t just a tournament. It’s a war for the future of Celestia. And not everyone will survive.

Months have passed since Ethan Blaze and his team defied the odds in the deadly Zero-G tournament, but the aftermath has shaken Celestia Prime to its core. The Protocol—once a guiding force of order—has begun to change, restricting freedoms, dividing society, and setting the stage for a new war. The city, once a beacon of equality, is now ruled by a brutal hierarchy where access to power, wealth, and even survival depends on the level of one’s citizen card. As Ethan struggles to unite his guild, the Boston Eagles, and uphold Nathan Clark’s vision of democracy, Zhang Mei, Ivy Thorne, and Solomon Stone move swiftly, seizing control of key infrastructures and turning Celestia into a battleground for dominance. Meanwhile, in the shadows, Lucas Murdock and his Solarian army resurface, stronger and deadlier than ever, threatening to tip the balance of power once again. But when Ethan receives a vision of Celestia’s true origins, he realizes that the war isn’t just about control—it’s about who controls reality itself. With the discovery of a mysterious element called Energonite, granting godlike abilities to those who wield it, the battle for the future of Celestia spirals into chaos. As alliances shift and betrayals unfold, Ethan must race against time to uncover the hidden truths buried in the Protocol, before the entire planet collapses into total war. With the stakes higher than ever, and the lines between friend and foe blurred, one question remains: Will Ethan rise as Celestia’s last hope—or become its greatest threat?
