House Bulwer of Blackcrown is a Reach house sworn to the Hightowers of Oldtown. Their seat stands upon the northern shore of Whispering Sound, a day's ride from Oldtown and within easy sight of the Three Towers of the Costaynes. The Bulwers blazon a bull's skull bone-over-blood and speak in their words what their device only suggests: Death Before Disgrace.
In the years before A Game of Thrones Lord Jon Bulwer kept Blackcrown for the Hightowers and married a Tyrell of Highgarden, Lady Victaria, to seal the line into the great Reach families. When the summer fever took him he left only one heir — Lady Alysanne, a girl of seven, who at the opening of the books holds Blackcrown in her small name while her uncles and bannermen keep the gate.
