Hugh was a Targaryen bastard born on the island of Dragonstone, and due to his heritage, he was one of the Dragonseeds recruited as a dragon-rider for Rhaenyra Targaryen, riding the dragon Vermithor. When the loyalists of Aegon II Targaryen marched from the Reach and besieged Tumbleton, Rhaenyra sent Hugh and Ulf the White to destroy their forces. However, the two chose instead to burn Tumbleton and Rhaenyra's garrisoned troops. Afterwards, they drank and whored with the victorious Aegon loyalists.
