In the fourth year of Vastoria, Lady Everly, the Imperial Consort, ordered the slaughter of the entire Fish Clan of the East Sea. One survivor remained: Amelia Mitchell. She disguised herself as a young eunuch and slipped into the imperial palace, revealing her true form in the imperial bathhouse, and captivating Callum Watson, the Emperor, who named her Lady Jade. Through a sorcery scandal, she turned the tables on Everly, rotting the consort's face. Then, with the Grand Tutor's help, she exposed the truth: Everly had given birth to a fish monster. Banished to the cold palace, Everly awaited her end, and on a stormy night, Amelia revealed herself to collect the blood debt, and the Emperor cut Everly's throat with a single stroke. But then Amelia uncovered the devastating truth: the one who had ordered the massacre of her clan was the man in her bed. In the end, she gave up her fish clan core and turned Callum into a fish, imprisoned for eternity.
