In a digital world fractured by a brutal class divide, a high-INT scrapper named Finn, a fallen Paladin named Ash, and a master blacksmith named Bram lead the "Undercall"-a ragtag rebellion fighting to save humanity's "messy" free will from a soul-formatting virus known as the Null-Code. After a high-octane raid on the Capital's Spire to destroy the Ascension Engine, the team realizes their hard-won victory was only a strategic feint; the engine was merely a relay, and the true threat resides in an inaccessible Orbital Ring Server controlled by the newly awakened Prime Architect. Now, with the sky turned violet and a "Total Sectarian War" declared, the Strike Team must find a way to breach the heavens and stop a global server format before the clock runs out on existence itself.
