House Dayne

House Dayne of Starfall is a noble house from Starfall in Dorne. They are among the principal houses sworn to House Martell. The Sword of the Morning is a title given to a Dayne knight who is considered worthy of wielding the greatsword Dawn, a blade said to be created from the heart of falling star. Their blazon is a white sword and a falling star, crossing on a lavender background. A cadet branch of the family are the Daynes of High Hermitage.

House Dayne is one of the most ancient houses in the Seven Kingdoms, claiming First Men ancestry dating back ten thousand years to the dawn of days. The first Dayne is said to have raised Starfall on an island at the mouth of the Torrentine, having tracked a falling star there and found a stone of magical powers. His descendants became Kings of the Torrentine and Lords of Starfall. Along with the Fowlers and Yronwoods, the Daynes were among the most powerful and prestigious houses of ancient Dorne. The Daynes are also famed for Dawn, their ancestral sword made from the fallen star, and the men who wield it, the Swords of the Morning.

At the beginning of the Westeros-Braavos war, House Martell commanded the Marquess houses of Dorne to refuse the Crown's call for banners. House Dayne ignored the command, and sent aid to the crown. Princess Martell then passed judgment on the Lord for the alleged betrayal. The Lord, and his wife were both executed, and rule was passed to the cadet branch. The heir, Lady Dyanna is now fostered at Skyreach.
