Serena, only daughter of the Black Dragon King and wife of Frost Dragon King Varian, hid three years to protect a Golden Dragon egg—blood extinct for ten thousand years. Coming home for her father's birthday, she was mistaken for a seductress by Dalia, the fox woman newly taken by her father. Dalia bound her with curse shackles, slashed her face, snapped her horns, stole her heart-protecting scale, cut open her belly, crushed the golden egg, and dragged her to the banquet as a "mistress." Serena survived and rose as Frost Queen. She exposed that Dalia's pregnancy was a lie, and watched Dalia get killed by her father.
