Challenger's Call
Nathan A. Thompson
When a sports injury ruins his body, memory, scholarship and place in the world, Wes Malcolm is offered a deal by the steward of seven worlds facing apocalyptic cataclysms: save her worlds, and he can take part of the power he gains back to his original body on Earth. Across ten volumes Wes grows from a damaged teenager into the Challenger-Lord of Avalon — delving dungeons, surviving tribulations, raising lights on fallen worlds, warring on false heavens, seizing crowns in the Golden Sands, descending into Avalon's depths, and braving the Trial of Horns on Pangea — accumulating might, magic, thrones and allies world by world. (Compiled from verified Goodreads volume descriptions.)
Progression: Explicit cross-world power accumulation is the backbone: Wes earns transferable power in Avalon and its six sister worlds that carries back to his Earth body; advancement is marked by rites and tribulations (dungeon delves, the Trial of Horns), ranked titles (Challenger, Challenger-Lord of Avalon, lord of multiple worlds), and ever-escalating authorities — thrones, crowns, and ancient rites of power contested against tyrants, false gods, and awakened ancients. Every volume marks the next rung: new world, new cataclysm, new crown. Categorized LitRPG (r/litrpg) with game-like growth mechanics.
