Alester Arryn

Alester Arryn is Lord of the Eyrie, Defender of the Vale and Warden of the East, and the only son of former Lady Astora Arryn, and her husband, Dollen Hunter. Through his aunt Shiera, Alester is a cousin to the late Daeron Waters, and his sister Visenya, though he was only a child during the Second Dance, and therefore did not participate in any of the fighting.

After the war, he served as a Ward of Queen Elaena I in King's Landing, in order to ensure the loyalty of the Vale, where he was married to Lady Sansa Harte, a former handmaiden on the Queen.

After the War
Following the conclusion of the Second Dance, and the death of his mother, Alester ascended to the paramountcy of the Vale, though he would not be permitted to hold court at the Eyrie for several years. Instead, he was held as a ward for Queen Elaena I, meant to ensure the loyalty of the Vale during the fragile time of reconstruction.

He proved to be a very difficult child, and mourned heavily the death of his mother and cousin, turning to strange practices some might consider occult. During his time in the capital, Lord Arryn made a solemn oath of fast, that he would live without luxury and only sustain himself upon bread and water until such a time that the true rules of Westeros could return.

Despite his rebellious nature, Alester was not considered an active threat, and was allowed to return to the Vale several years later for good behaviour, following his promise to marry Lady Sansa Harte, a loyal servant of the Queen.
