Seraphina, a princess from the human kingdom, is sold to the Black Dragon lord Draken as a breeding‑tool because of a silver birthmark on her face. She later discovers she is the last heir of the exterminated Silver Dragon royal bloodline. Framed by jealous golden‑dragon noble Lilith, she fakes adultery, escapes off the Soul‑break Cliff and awakens her true silver‑dragon power in the sacred spring. Five years later, she returns to the Dragon Realm with her twin children — hot‑tempered black‑dragon boy Aiden and wise silver‑dragon girl Luna. At the centennial Dragon Conclave, she reveals the truth of the frame‑up, proves the kids are Draken’s biological offspring. Together with Draken and the two gifted children, she fights against greedy Golden‑Dragon forces, defeats the sealed Shadow‑Dragon King, revives the Silver‑Dragon clan, resolves the feud between races, and finally gains genuine love and a complete happy family.
