Sinopsis Queen's Revenge

Cora, the first golden-tailed mermaid queen, was betrayed and killed by the perch spirit Caden who stole her heart. She revived via tides with lost memories, adopted by her foster sister Mila and wed the disguised Caden. Regaining her memory, Cora saw Mila swapped their clans’ daughters. She nurtured Mila’s girl Sierra into a golden tail with iridescent reverse scales, and crafted artificial life Lila as her vengeance pawn. After a thousand years’ plan, she struck at the Sea King’s coronation. Cora publicly exposed the swapped eggs and Caden’s true perch form, reclaimed her mermaid heart and slew her foes.
