A Weyr is the home for a collection of @Dragons, @Dragonriders, and support staff. The function is to house those who fight Thread. Weyrs are usually established in craters of extinct volcanoes. They are a complex system of smaller weyrs, or caves, for habitation and everyday activities. These caves are carved out of the crater rock, some with large stone cutting machines and later, when all the machines had broken, by hand. A careful observer may discern the older parts of a Weyr by the way it was carved and may assume that smoother walls were carved sometime before the second pass. Each larger Weyr consists of individual weyrs, a Hatching Grounds, Weyrwoman's Quarters, a Council Room, a Records Room, Lower Caverns, Weyrling Barracks, Feeding Pens, a lake, and Star Stones.
Each @Dragonrider and @Dragon pair has their own individual living quarters. Riders move there from the Weyrling Barracks after their dragons mature. Northern Riders have their weyrs built into the sides of the craters, with ledges for dragons to sun themselves and to enter and exit. Due to a lack of caves on the Southern Continent, riders located there have more traditional open-air cots, with large sand wallows located nearby for their dragons.
Each Weyr has its own hatching grounds, where Queens lay their clutches. Hatching grounds are located in large caverns filled with heated sands which help the eggs to harden. The area is typically large enough for dragons and people to view the hatching
Weyrwomen have their own quarters which are larger and more elaborate than typical weyrs. Each Weyr typically has about three to four such areas, to house multiple queens.
Each Weyr has a large room to serve as a meeting room for important meetings and discussions. The Records Room holds all the physical documentation that contains the history of the Weyr and the necessary information for the Weyrs operations.
The lower caverns are the cave systems of the Weyrs located on the Northern Continent where the support staff and those not paired with a dragon or partnered to a dragonrider live and work in support of the Weyr's operations. The lower caverns are also where the kitchen and dining cavern are located.
The stores are the storage areas where all the shared supplies and equipment of the Weyr are stored.
The Weyrling Barracks serve as the quarters for Weyrlings, who live communally during the two-year dragon maturation period. In crowded Weyrs, some older dragons may be forced to remain in the Weyrling Barracks due to a lack of available weyrs.
Each Weyr has dedicated feeding pens that serve as the holding place for the herdbeasts (cattle) that Weyrs maintain to feed their dragons. Weyrs typically rely on lakes as a source of fresh water.
Each Weyr has a configuration of stones known as Star Stones. The stones consist of both an Eye Rock and a Finger Rock. The stones are used to predict the start of a pass when the Red Star is seen bracketed in the Eye Rock at the tip of the Finger Rock.
