Gormon was sour-mouthed, with a well-trimmed beard colored grey, black and white.
Lord Gormon was a supporter of Daemon Blackfyre during the First Blackfyre Rebellion. He was considered one of the greatest knights of his time. He slew Lord Hayford and Roger of Pennytree at the Battle of the Redgrass Field. After the rebellion, he bent the knee and was pardoned by King Daeron II Targaryen. For the part he had played in the rebellion, however, Peake was stripped of two of the three castles House Peake had held for centuries.
It is said that Gormon became blind to reason in his thirst for revenge and the recovery of his seats. Years later, during the reign of King Aerys I Targaryen Lord Gormon convinced Daemon II Blackfyre, the eldest surviving son of Daemon I, to return from across the narrow sea and try to claim the Iron Throne. He traveled with Daemon and his entourage to the Whitewalls Tourney of 211 AC, where the conspirators were to meet, encountering Ser Duncan the Tall and his squire along the way. During the tourney, Gormon plotted with Ser Tommard Heddle to make Daemon the winner of the tourney. After the dragon egg, which the winner of the tourney was to receive, went missing, Gormon had a rock painted in the same fashion and planted in the belongings of Ser Glendon Flowers, framing the youth for the theft which resulted in Glendon being imprisoned and tortured. Gormon advised against permitting Flowers a trial by combat, but Flowers received a chance on Daemon II's insistence and managed to prove his innocence by unhorsing Daemon II in their first tilt. Next, Gormon's plans of Daemon claiming the Iron Throne were foiled when Lord Brynden Rivers, the Hand of the King, arrived at Whitewalls and besieged the castle. After Daemon was captured, Gormon was among the lords executed for his role in the Second Blackfyre Rebellion.
The maesters at the Citadel have argued ever since why Ser Aegor Rivers chose not to support Daemon II in his rebellion. Many claim that Gormon and Daemon were unable to convince Ser Aegor that their plan had merit.
