The Last Dragon King‘s Bonded

Dragon Emperor Waldric is betrayed by his adopted son Draven, poisoned, stripped of power, and cast into the abyss. Draven’s attempt to steal his essence backfires, trapping his soul in the void.
Waldric awakens in Kane Westland, a frail half-blood mocked for having no dragon bond. At his grandfather’s celebration, Kane claims the Dragon Emperor’s Scepter, walks across lava, and awakens the ancient dragon Zepharion, which bows only to him. He defeats the Sterling family’s strongest rider and becomes Lord of Westland, but his sister Layla fears he is no longer her brother.
A forbidden ritual pulls Draven’s soul into Waldric’s corpse, creating a false Dragon Emperor. At the memorial, the scepter rejects him, exposing the fraud. In the final battle, Kane purifies Draven’s soul, revealing he had already bonded with an ancient dragon, and his hatred destroyed him for nothing.
Kane abolishes the pure-blood system, ruling that dragon bonds depend on soul compatibility. But when Layla asks if her real brother remains inside him, Kane has no answer. As she walks away, an ancient dragon eye opens in the void. The war for Kane’s soul has only begun.
