Long ago, the humans used dark magic, and were driven off by the dragons and elves to one end of the continent. Now, after humans killed the dragon king and his egg, war is imminent. As forces gather, the elves attempt to assassinate the human king Harrow and his heir, the young prince Ezran. One among the elves, the young Rayla, along with Ezran and his brother Callum, discover that the dragon king's egg wasn't in fact destroyed, but stolen.
Together they undertake to return the egg to the dragons to prevent war. But the mage Viren, King Harrow's advisor, is intent on war. He seizes power after the king dies in the assassination attempt, and sends his children Claudia and Soren after the fugitives.
The Dragon Prince is not yet Cancelled or Renewed for Season 4
