House Arryn

House Arryn of the Eyrie is one of the Great Houses of Westeros, and is the principal noble house in the Vale of Arryn. Their main seat is the Eyrie, which is considered impregnable. House Arryn has several other holdings, including their winter castle at the Gates of the Moon, which was once their main seat. Both of these fortifications sit astride the Giant's Lance, the tallest mountain in the Vale, the Gates of the Moon at its foot, the Eyrie at its top.

The Arryns are considered to come from the oldest and purest line of Andal nobility, which they say reaches back to Andalos and possibly Hugor of the Hill. House Arryn claims its founder in the mythical hero Artys Arryn, the Winged Knight.

Duke Hugor the Siegebreaker, Warden of the East, is regarded as one of the most accomplished Lord in the Narrow Sea War. Few knights from other regions of Westeros will fight from high in the air. It is an exceedingly dangerous assignment. However, Lord Hugor has amassed and trained a force of skilled and armored sky-cavalry who are effectively able to fight from the skies.

Lord Hugor led his forces across the Narrow Sea and captured three separate Braavosi keeps, and slaying the Titan’s Fist, a mercenary of vast renown.
