Fans of the series have spotted this hidden gem while looking for easter eggs. A replica of Gandalf's sword, Glamdring, from the "Lord of the Rings" and "Hobbit" trilogies is forged inside the Iron Throne. Sean Bean (Eddard "Ned" Stark) played Boromir in the "Lord of the Rings" film trilogy. While it might seem like a cool nod to the beloved wizard, Gandalf's sword being part of the throne is only a matter of practicality. The people who created the throne used whatever molds were already available to them, and Glamdring happened to be one of them.
