The Cordaxis Protocol: A Sci-Fi LitRPG Apocalypse 4x Adventure

by Mike Spurlin

A unique LitRPG adventure where sound is a weapon and the world's code is waiting to be rewritten. In a universe suspended over an endless abyss, weight is a variable and frequency is everything. Kael Vance is a Level 0 Scrapper clinging to the rusted underbelly of the Cordaxis—a vertical world of fraying cables and toxic updrafts. Survival means scavenging enough scrap to pay the local Shelf-Tax. Failure means a lethal fall into the Null. Everything changes when Kael uncovers a pristine Architect pod hidden in the Depth-Sliver and absorbs a dormant Administrator core. He is forcibly upgraded to a Fray-Stitcher, a unique class capable of seeing the world's underlying code and manipulating its physical frequencies. The upgrade paints a massive target on his back. The High-Lumos elites are siphoning the world's foundational tension to power their floating cities, causing the lower shelves to rot and collapse. As Echo-Hunters and Null-Sentinels descend to mute his unsanctioned frequency, Kael must quickly master his new abilities. He has to balance his Cohesion, Tempo, and Capacitance while managing lethal Static buildup to survive high-speed vertical combat. To protect the survivors of a falling city, Kael will have to break the fundamental laws of the Cordaxis and rewrite the Great Song himself.
