No Class, No Ceiling

Everyone gets seven days in the tutorial. Ren Kael got many years. When a portal malfunction traps sixteen-year-old Ren inside a Primordial Zone — an ancient, broken world that predates the System itself — he has two choices. Survive or don't. There is no third option, no rescue, no guide voice, no skill tree to follow. Just an enormous hostile world, an exit portal that drifts and disappears, and all the time in the world to become something the System never anticipated.
