The Gates of the Moon
The Gates of the Moon is a castle of moderate size that guards the path to the Eyrie. It has often served as a winter seat for House Arryn, and is always garrisoned to help prevent any attempt at besieging or capturing the Eyrie. The castle is currently held by Lord Nestor Royce. Originally, Royce was only a temporary caretaker, but Lord Protector Petyr Baelish granted him ownership of the Gates of the Moon after the War of the Five Kings.
Younger brother to Yohn Royce. He was caretaker of the Gates of the Moon.
