When riots broke out in King's Landing, Arthor was in the manse of his kinsman, Lord Bartimos Celtigar, who served as master of coin to Queen Rhaenyra Targaryen. The building was overrun by a mob, and Arthor made a brave stand in a doorway, holding the mob at bay briefly with a sword, until a treacherous serving girl let rioters in from a back way. Arthor was slain when he was stabbed in the back with a spear wielded by one of the throng.
