Starfall is a great castle on the shores of the Summer Sea, situated at the mouth of a river which spills out into a bay. One of the towers of the castle, which stands next to the water, is called the Palestone Sword. The Sword of the Morning is a title given to a Dayne knight who is considered worthy of wielding the greatsword Dawn.
The current lord of the house is Edric Dayne, squire to Lord Beric Dondarrion after the Lord of Blackhaven espoused his aunt Lady Allyria. He is nephew to the deadliest knight of Aerys’s Kingsguard, Ser Arthur Dayne, the Sword of the Morning, and his sisters, the beautiful Lady Ashara and Lady Allyria, by their elder brother. Ser Arthur died at the Tower of Joy, killed by Lord Eddard Stark and Lord Howland Reed. Lady Ashara had been a lady in waiting to Princess Elia of Dorne for a few years when she went back to Starfall for unknown reasons. Given Dawn and the news of her brother’s death by Lord Eddard, she threw herself into the Summer Sea from the Palestone Sword. Her body was never recovered.
