Sword Saint of House Dayne

His soul transmigrated to Westeros, becoming the younger brother of Arthur Dayne, the Sword of the Morning. Watching the Morning embark on his journey, young Louis knew he had to become powerful as quickly as possible. In Aegon's 289th year, he won his first tournament in Lannister Harbor. In 294th year, he defeated Barristan Selmy, captain of the Kingsguard, and then defeated all the strongest warriors in Westeros for three consecutive years, earning the title of the greatest knight of the Seven Kingdoms and being hailed as the nemesis of all swordsmen in Westeros. Nickname—Devil's Muscles... oops! The Master Sword Saint—Louis Dayne! (A Game of Thrones fanfiction, "The Death Knight of House Lannister," already exists.)
