Game of Thrones Series
This is a series of caches named after a number of cities of the Seven Kingdoms on the continent of Westeros in Game of Thrones.
The Eyrie
The principal stronghold of House Arryn. It is located in the Vale of Arryn near the east coast of Westeros. The Eyrie straddles the top of a peak in the Mountains of the Moon several thousand feet above the valley floor below. It is approached by a narrow causeway and road. Those who would approach the Eyrie must pass through three way-castles guarding the ascent - and then, must proceed in single file, making them very vulnerable to archers. For these reasons, the Eyrie is considered impregnable to any attack that does not involve dragons.
The High Hall of the Eyrie is the main audience chamber, where the Lord of the Vale greets visitors from a throne made of weirwood. A notable feature of the chamber is the Moon Door, a hatch built into the floor through which people can fall to the floor of the Vale far below. Being thrown through the Moon Door is the preferred method of execution at the Eyrie.
Prisoners at the Eyrie are incarcerated in the "sky cells", cells which are open on one side to the air. There is a very slight slope in the cells, and prisoners must be careful not to roll out of the cell in their sleep and plummet to their deaths.
Coordinates may be off by a few feet. You are looking for a camo'd Bison Tube. Please recover so muggles don't spot it. Look for a group of small trees on the side of the trail just past the wooden bike jump.
