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 at least one other holding, 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 Arryn sigil is a sky-blue falcon soaring upwards, outlined against a white moon on a sky-blue field, and their words are "As High as Honor".

Kings of Mountain and Vale
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.

When King Robar II Royce began to unite the First Men and defeat some of the petty Andal kings during the Andal invasion, the Andals of the Vale united behind Ser Artys Arryn, the Falcon Knight, a native Valeman esteemed amongst his peers as the finest warrior of his day. Robar was slain in the Battle of the Seven Stars, possibly by Artys, and the First Men houses who remained bent the knee and swore fealty to Artys Arryn, the First of His Name, new-crowned King of Mountain and Vale. From that day, the Vale became known as the Vale of Arryn. Songs of the Vale conflate Artys with the legendary Winged Knight, who is said to have slain the Griffin King atop the Giant's Lance. The First Men who did not accept Artys as their king were forced into the Mountains of the Moon, becoming the Vale mountain clans.

The Arryns initially lived at the Gates of the Moon, but over generations they constructed the Eyrie. They often used the Eyrie as a summer pleasure palace, descending to the Gates of the Moon before winter made the Eyrie inaccessible.

The Arryn kings added Pebble, the Paps, and the Witch Isle to their realm. They battled with the Stark Kings of Winter over the Three Sisters in the War Across the Water, which featured King Osgood Arryn and his son and successor, Oswin the Talon, who burned the Wolf's Den. There were bloody battles wherein the Arryn fleet turned back slavers from Volantis, ironborn reavers, and pirates from the Stepstones and the Basilisk Isles. The legendary Lady Alyssa Arryn gave her name to Alyssa's Tears, a waterfall on the Giant's Lance, when she did not shed a tear for her murdered husband, brothers and children.

Aegon's Conquest
During Aegon's Conquest the Arryn and Targaryen fleets fought in a battle in the waters off Gulltown, which resulted in the destruction of the Targaryen fleet and the death of its commanding officer, Daemon Velaryon. Visenya Targaryen, on her dragon Vhagar, burned the Arryn fleet in response. Since both fleets were destroyed, the battle was considered a tactical draw, but a strategic defeat for the Targaryens as they were unable to take Gulltown. For House Arryn the trouble did not end there, since the Sistermen on the Three Sisters revolted after the destruction of the Arryn fleet.

Later in Aegon's Conquest, Visenya was charged with subduing the Vale. Sharra Arryn, Queen Regent of the Vale, ruling in the name of her son, the boy-king Ronnel Arryn, amassed the Vale's army at the Bloody Gate. Visenya, however, flew on Vhagar to the courtyard of the Eyrie to obtain the surrender of the Vale of Arryn. When Sharra returned to the Eyrie she found her son sitting on Visenya's lap asking if he could ride the dragon with her. Once Sharra yielded and bent the knee, Ronnel twice flew with Visenya and Vhagar. The Arryns have since remained Defenders of the Vale and Wardens of the East for the Iron Throne.

Targaryen Era
Queen Rhaenys Targaryen arranged the marriage Lord Ronnel Arryn to the daughter of Lord Torrhen Stark of Winterfell, in an attempt to knit the new realm together. There are letters at the Citadel which suggest that Torrhen only agreed to this match after much protest, and that his sons had refused to attend the wedding. In 37 AC Ronnel was deposed by his brother Jonos. When House Royce gathered forces against Jonos and besieged him in the Eyrie, Jonos threw Ronnel and his family through the Moon Door. Prince Maegor Targaryen flew to the Eyrie on Balerion, and hanged Jonos and his supporters. House Arryn continued through a cousin, Hubert Arryn.

In 80 AC, during the reign of King Jaehaerys I Targaryen, Lord Rodrik Arryn married Princess Daella Targaryen, the king's daughter. Daella died in childbirth, giving birth to their only child, Lady Aemma Arryn. Aemma was married to Prince Viserys Targaryen in 93 AC. By the time Jaehaerys called a Great Council in 101 AC, Rodrik was deceased as well, and Lady Jeyne Arryn ruled the Eyrie. However, as she was in her minority in 101 AC, House Arryn played a small role in this council.

Upon the death of Jaehaerys in 103 AC, Prince Viserys was crowned king and Aemma Arryn his queen. During the early years of their marriage, Aemma gave birth to a stillborn son and suffered multiple miscarriages, though she also gave birth to a daughter, Rhaenyra Targaryen, in 97 AC. Aemma died giving birth to her second son, Baelon, who followed her to the grave a few days later.

Following the death of Viserys I in 129 AC, House Arryn became involved in the Dance of the Dragons, where Aemma's daughter, Viserys's elder child and proclaimed heir, Princess Rhaenyra, and Rhaenyra's younger brother, Prince Aegon, Viserys's eldest surviving son, fought over their claims to the Iron Throne. Jeyne Arryn, supported the blacks and her kinswoman Rhaenyra. At the start of the Targaryen civil war, Prince Jacaerys Velaryon, Rhaenyra's eldest son, travelled to the Eyrie to secure aid for his mother's cause. Jeyne kept true to her promise and sent men by sea by way of Gulltown to join Rhaenyra's hosts.

Following the conclusion of the civil war, and the coronation of King Aegon III Targaryen, Rhaenyra's eldest surviving son, at the age of eleven, Jeyne became one of seven regents of the young king. She died in Gulltown of illness in 134 AC.

This led to a succession struggle. Jeyne's will named her fourth cousin Joffrey Arryn as heir. However Jeyne's first cousin Arnold Arryn had been imprisoned for trying to depose her but his son Eldric Arryn pushed their claim. A more distant cousin, Isembard Arryn, Head of House Arryn of Gulltown, also pushed their claim. Even though Eldric was eventually killed Arnold continued to oppose Joffrey. Finally Arnold and Isembard were forced to submit to Joffrey.

First Blackfyre Rebellion
On the Second Moon of 196 AC, a tourney and feast was arranged by King Daeron II Targaryen in the honour of the wedding between Aegor Rivers and Calla Blackfyre. House Arryn also attended the festivities under Lord Donnel Arryn.
