 The Eyrie is the smallest of the great castles in the story, consisting of seven slim towers bunched tightly together.It has no stables, kennels, or smithies, but the towers can house 500 men, and the granary can sustain a small household for a year or more.The Eyrie does not keep livestock on hand; all dairy produce, meats, fruits, vegetables, etc., must be brought from the Vale below.
