- "Gimme some skulls to crack and I'll be happy any day."
- ―Geldon to Caspus Harlaw.
Geldon Goodbrother is a recurring character in the second, sixth, and seventh seasons. He is an ironborn raider from a lesser branch of House Goodbrother and is a crewmember of the Reaper's Bounty, serving as one of Caspus Harlaw's most trusted liueutenants. He also serves as the Castellan of Ten Towers.
He suffered grievous wounds during the Siege of Snake Mount, so bad that Caspus sends him back to the Iron Islands to recover. By the time that Euron Greyjoy is elected the new King of the Iron Islands, Geldon has fully recovered from his injuries and, alongside Caspus, supports Yara Greyjoy's claim to the Salt Throne.
