Berta Rowan is the only child of Lord Mathis Rowan after the deaths of both her brothers. Lord Jon Arryn has ordered her to become the ward of House Jasper to ensure the good behavior of House Rowan after Robert’s Rebellion.

While en route to wed the heir of House Mullendore her wheel house was set upon by Carsen and Jardon. The former threatened her sworn shields (Ser Bert and Ser Wilber). Wendall drove the wheel house to the safety of Uplands while the knights beat back the aggressors.
