Luthor Tyrell (son of Theodore)

Lord Luthor Tyrell was the only son of Lord Theodore Tyrell and his wife, Lady Lia, and the older brother of Elinor Tyrell. He was one of only a handful members of House Tyrell not present at the Great Sept of Baelor when it was destroyed, surviving the attempted annihilation of his House alongside his father and mother. After a brief exile in Oldtown, Luthor and his father retook Highgarden from the Lannisters, and after the Great War, pledged their allegiance to King Gendry I Baratheon, primarily at Luthor's behest. Luthor eventually succeeded his father as Lord of Highgarden, Lord Paramount of the Mander, and Warden of the South after his father's death during the War of the Narrow Sea.
