Synopsis

After Caroline saves the Royal Capital with her elemental core, her fiancé Killian—believing a rival's lie—rips the core from her body and abandons her, while the rival steals her fame and even her baby dragon. Left to die in a blizzard, Caroline is saved when her loyal beast restores her core with seven-colored magic—and now she enters the realm's greatest elemental tournament to reclaim her stolen glory and make every traitor pay.
