Valerian

Valerian is a household name - everyone knows the prince of the illustrious Castle Island, the "crown jewel of the sea." Despite his renown, however, he's been unable to find the help he needs to complete his critical quest to save the king's life. When he meets Poppy, he promises her great wealth if she assists him: countless jewels, priceless relics, and most importantly, the privilege of working by his side.
