Rivera's Repairs: Dungeon Repairwoman
B69/100Web serial by M.S. Davidson
Nineteen-year-old repair technician Tess Rivera lives on Tertius-Prime, a crumbling megacity built atop a dungeon that has been "cleared" for twenty years. The power grid fails nightly, her father's health is declining, and their freighter-home is one broken component away from becoming a coffin. When desperation drives her into the dungeon's outdated tutorial system, it malfunctions—and Tess fixes it herself, accidentally acquiring a {null} class no one has ever heard of. No combat skills, no normal leveling. Just the ability to see dungeon code, interface with broken systems, and talk to an AI that has been alone for far too long. The "cleared" dungeon is not empty. It has just been abandoned. And Tess's "broken" class might be exactly what is needed to wake it back up.
