Evan, a working-class EMT with no special destiny, opens a mysterious crate and puts on an ancient dragon mask — and is instantly transported to the world of Inati as a massive black dragon with glittering breath and a growing hoard instinct. He lands in the broken city of Hatra, where a priestess and her people are under assault by zombie-like monsters unleashed through a crack in reality called the Breach. To survive, Evan must master his new draconic body, earn the trust of a king, and start rebuilding a city that has been crumbling for generations.

Evan is unpretentious, brave, and genuinely decent — qualities that make his rapid rise to power feel earned rather than arbitrary. His EMT background gives him a protective instinct that translates naturally into his new role as city lord and protector of Rahma. As his draconic nature deepens he develops a hoarding mentality and territorial pride, but his humanity keeps him relatable across all twenty-two books.

Across twenty-two books Evan transforms from an out-of-place EMT into a Dragon Lord, then a Dragon Emperor, accumulating Noble Swords, bonded mates, dragon-children, and an ever-expanding harem of powerful women who choose him as their lord. The Green Glass Sect and their leader Olivier provide the mid-series conflict before giving way to the Demon King of the Underworld as the final antagonist threatening to break through the Breach and destroy Rahma. The series traces a classic 'weak-to-strong' progression fantasy arc that also leans into kingdom-building and cultivation, culminating in Evan leading the assault through the Breach itself to end the demonic threat permanently.
