Note: This is a fantasy story that references real historical figures, but does not correspond to historical facts. It tells a story about Grand Prince Seongnyeong (Yi Jong), the son of King Taejong (Yi Bang-won), who was deposed and abandoned on a secluded island by his own father to prevent bloody power struggle within the royal family that could arise because the problematic Crown Prince Yangnyeong (Yi Je) lacked the qualities for kingship.
