Fan Casting Ten Thousand Ships

Set roughly one thousand years before the War of the Five Kings, the story follows Princess Nymeria of the Rhoynar after her people are defeated in a devastating war with the Valyrian dragonlords (ancestors of House Targaryen), and she rallies the survivors to flee Essos in a refugee fleet of "ten thousand ships" in search of a new home. Their journey takes them to many different lands around the Summer Sea, from the dinosaur-infested jungles of Sothoryos to the tropical paradise of the Summer Islands, before they finally migrate to Dorne, becoming the ancestors of the modern Dornishmen and House Martell.
