More than seventy-five years ago, the Adumbrae manifested in our world, possessing humans and turning them into monsters of destruction, abruptly ending the Second World War. Just as mysteriously, Corebrings came to humanity's aid. With powers granted by the Mother Core, these superhumans continued to protect the world to this day. Erind Hartwell, a first-year law student incapable of empathy, guilt or remorse, is offered powers by an entity at the brink of death and must navigate a world of monsters and superhumans.
Progression: Corebring / Mother Core progression is central and explicit. Verified via Goodreads series 341177 and book blurbs: (1) Mother Core grants superhuman powers to Corebrings, creating a clear tiered power system; (2) Adumbrae possession creates monster progression on the enemy side; (3) each Arc (1-4) tracks Erind Hartwell's advancement from no powers to gaining and mastering Mother Core-granted abilities at death's door; (4) quantified via Goodreads tags level1 / royalroadseries / webserial and Reddit r/ProgressionFantasy confirmation 'definitely progression fantasy'. Progression is the engine: survival and rank among Corebrings depend on mastering and leveling Mother Core powers.
