He Chose His Dragon Heir, I Took Back the Realm

Talia Aurelian, rightful heir to the Golden Crown Dragon Domain, renounces her title and sacrifices everything to save her beloved Everic's dying Ash Dragon Domain. She pours three thousand gold crystals into reopening mines and trade routes, and even peels three of her own life dragon scales—two to stabilize the dying ancestral furnace, one to repair Everic's shattered dragon core. Ten years later, the Ash Domain has risen from oblivion to a northern powerhouse with nine dragon furnaces. Yet Talia is reduced to a childless, income-less housewife, her contributions forgotten—even by Everic himself. A retired dragon rider's warning leads her to a hidden dragon-mate seal inside Everic's saddle, exposing his three-year affair with Mirella, who is eight months pregnant in a nest bought with Talia's own gold crystals. Worse, Everic plans to steal Talia's life scales to forge a fake golden-flame heir, then divorce her with a pittance of twenty low-grade crystals. Talia does not confront him immediately. She quietly audits every ledger with an oath officer, then returns to her homeland, where her grandfather confirms her inheritance has never been revoked. At the grand scale-changing ceremony, Everic publicly parades Mirella as his lady and seats her in the lord wife's throne. Talia steps onto the altar and dissolves their blood-flame contract in front of all six clans. Her recalled life scales extinguish the false golden flame; the child is exposed as ordinary red-flame blood and hatches prematurely from the backlash. Back in Golden Crown, Talia legally reclaims her personal assets, outstanding debts, and diverted trade revenues. The Ash Domain's economy collapses overnight. Everic finally learns his dismissed wife is the sole heir of the most powerful dragon domain. Mirella, fighting for her child and promised wealth, falls from the breeding tower and loses her dragon wings. Everic, stripped of his lordship, sells his last remaining assets to Talia for three thousand gold crystals—a transaction, not atonement. A year later, Talia walks the long steps of the Golden Crown throne alone. Ten years ago she set down her crown for love; now she places it back on her own head—as the new Lord of the Golden Crown Dragon Domain.
