Ser Romny Orben was a knight from the Reach and the father of Allun Orben.
Along with Ser Pharus, his brother Ser Tarman and other men from House Orben, they fought for House Tarly against Robert Baratheon. After the deaths of Ser Pharus and Tarman, Romny became the new head of House Orben until he was killed by men from House Durwell. His wife died when their son Allun was five years old. Allun would later become the new head of House Orben when he was knighted.
