Gregor Forrester

Lord Gregor Forrester, the Lord of Ironrath, is lord of a strong Northern House and a bannerman of House Glover, who are in turn loyal to the great house of the north – the Starks. As a youth, he famously arm-wrestled Galbart Glover for the privilege of becoming the man's squire; Glover later joked that he'd gladly lose the match all over again. After his father died at the Trident, Gregor ascended to the lordship, and married Elissa Branfield at the behest of Robert Baratheon.
