The Vale of Arryn

The Vale of Arryn is one of the constituent regions of the Seven Kingdoms, and was formerly a sovereign nation known as the Kingdom of Mountain and Vale before the Targaryen Conquest. The Vale was sieged and conquered by house Barraclough, Jerron The Bear. The house Barraclough helped The Vale prosper and become shape its greatness until The Bear was assassinated by a runoff pack of The Watchers trying to claim nobility, Now it is ruled by House Arryn from the castle known as the Eyrie. Protected and surrounded by the Mountains of the Moon, the Vale is isolated from the rest of Westeros and is accessible only during warmer seasons.

Bastards born in the Vale are given the surname Stone.

The Vale is where the Andals first landed and spread out from during their invasion of Westeros six thousand years ago, though as settlement patterns became established, the Reach became the main population center and cultural heartland of the Andals. Still, combined with its isolated mountainous terrain, noble families from the Vale are said to have among the purest Andal bloodlines within Westeros. A few noble families from other regions can match them for this, but no other region taken as a whole.

There are many small tribes who inhabit the foothills of the Mountains of the Moon. These tribes are commonly known as hill tribes, and they reject the rule of House Arryn. Although they are dangerous to passing travelers, their lack of organization and less advanced weapons means they pose no real threat to the rest of the Seven Kingdoms.

Geography
Unlike the Westerlands, which have gently rolling mountains, the mountains of the Vale are much less hospitable and more difficult to traverse. Further, while the mountains of the Westerlands are filled with precious metals such as gold, the mountains of the Vale are not particularly rich in resources. The valleys scattered between the harsh mountains, however, are as fertile as any in the Riverlands.

In the books
In the A Song of Ice and Fire novels, the term "Vale" refers to the entire region ruled by the Arryns, as well as the Vale itself, which runs from the foot of the Giant's Lance almost to the sea,. The Arryns rule the Vale from the castle known as the Eyrie. Before the Andal Invasion, the region was originally known as the the Kingdom of Mountain and Vale. During the time the Arryn dynasty ruled the Vale, the region was also alternatively known as the Kingdom of Vale and Sky.

The people of the Vale, popularly called "valemen", are known as honorable, reliable warriors steeped in honor and the worship of the Faith of the Seven.

Some of the valemen living in the foothills of the Mountains of the Moon have rejected the authority of the Eyrie and exist as little more than clans and tribes of savage warriors, such as the Black Ears and Burned Men. While dangerous to passing travelers, they lack the number and equipment to properly invade or trouble the Vale.

The borders of the Vale are held to be the Bite to the north, the Bay of Crabs to the south, the Mountains of the Moon to the west and the Narrow Sea to the east.
