House Arryn

"The Arryns are direct descendants of Andal invaders... who sailed across the Narrow Sea and came ashore at the Fingers."

- Catelyn Stark

House Arryn of the Eyrie is one of the Great Houses of Westeros. It has ruled over the Vale of Arryn for millennia, originally as the Kings of Mountain and Vale and more recently as Lords Paramount of the Vale and Wardens of the East under the Targaryen kings and Baratheon-Lannister kings. The nominal head of House Arryn is Robin Arryn, the Lord of the Eyrie, with his stepfather Petyr Baelish acting as Lord Protector until he reaches the age of majority.

Their lands are in the central-eastern region of the continent. Their seat is the Eyrie, ancestral seat of the Mountain Kings. House Arryn's sigil is a white crescent moon and falcon on a blue field. Their house words are "As High as Honor."

At the start of the series, Lord Jon Arryn was killed under suspicious circumstances. His widow Lysa blamed House Lannister and sought refuge in the Eyrie. Despite her enmity towards the Lannisters, she remained neutral in the War of the Five Kings and aimed to use the forces of the Vale to defend Robin and the Eyrie if necessary. After killing Lysa and making it appear like an accident, Lord Petyr Baelish becomes Lord Protector of the Vale until young Robin comes of age. Under his rule, supervised by Baelish, the Vale assists House Stark in toppling House Bolton in the North during the Battle of the Bastards. After the battle, the Vale declares for House Stark and becomes part of the Kingdom of the North in defiance of the Iron Throne, though they later return to the jurisdiction of their historic rulers, House Targaryen, after Jon Snow bends the knee to Daenerys Targaryen.

Background
According to legend, the house was founded by Ser Artys Arryn, the Winged Knight. He is said to have flown atop a giant falcon, landing on the topmost mountain of the Vale, and defeated the Griffin King, the last of the First Men Mountain Kings. Afterward, he took the Eyrie and became the first King of Mountain and Vale. His descendants continued to rule the Vale ever since. The Eyrie has never fallen to invaders. During the War of Conquest, House Arryn repulsed a Targaryen invasion at Gulltown with Braavosi aid, but ultimately bent the knee peacefully as they realized they could not fend off the Targaryens forever. By submitting peacefully instead of being conquered, they were allowed to continue to rule as Lords Paramount of the Vale and Wardens of the East in the name of the Iron Throne. The Eyrie is considered impregnable and defends House Arryn from the violent Hill tribes of the Mountains of the Moon.

Jon Arryn is the most recent head of House Arryn, Lord of the Eyrie, Warden of the East and Defender of the Vale. He was a respected nobleman and both Eddard Stark and Robert Baratheon fostered with him. The Mad King condoned the kidnap of Eddard's sister and Robert's betrothed, Lyanna Stark. The Mad King had Eddard's father and brother killed for protesting against the kidnapping. When he then demanded that Eddard be turned over to the King's justice, Lord Arryn rebelled, calling his banners to war. House Stark and House Baratheon followed suit. The rebels forged an alliance with House Tully through marriage, with Eddard married to Catelyn Tully and the then-elderly Jon to the young Lady Lysa Tully.

After the rebel victory in the war, Robert became King and appointed Jon as his Hand. Jon served the realm well for many years as Hand of the King. He died immediately prior to the events of the series, sparking King Robert's search for a replacement. Jon is survived by his wife Lysa and their six-year-old son, Robin. Jon was investigating the legitimacy of the children of Queen Cersei Lannister when he died. He found that they were not Robert's offspring by comparing their appearance to Robert's bastards based on the genetic preponderance for dark hair in House Baratheon.

Season 1
Lysa Arryn writes to her sister Catelyn Stark claiming that House Lannister were behind Jon's death. Lysa flees King's Landing with her son seeking the refuge of the Eyrie. When Catelyn receives the letter, Robert Baratheon is visiting Winterfell, the seat of House Stark, and asks Eddard to replace Jon as Hand of the King. Eddard accepts and begins an investigation into Jon's death. He learns that Jon may have been poisoned. Eddard uncovers Jon's findings about Queen Cersei Lannister's infidelity and Robert's lack of a trueborn heir. Robert still mistakenly believes that Joffrey Baratheon is his son.

Catelyn's son Brandon Stark survives two assassination attempts. Catelyn blames Tyrion Lannister and has him arrested. She brings him to the Eyrie to Lysa's chagrin. Lysa is attempting to isolate Robin from the rest of the Kingdom and use her role as regent to have the Vale lords protect him. She is still breastfeeding him despite his age, and her doting has spoiled him. Tyrion tricks Lysa into granting him a public hearing by claiming that he plans to confess. He instead demands and wins a trial by combat and is set free.

King Robert dies following a hunting injury. Eddard is arrested for treason when he challenges Joffrey's claim to the throne. Lysa withholds this news from Catelyn initially. Catelyn implores Lysa to lend her armies to march on King's Landing along with the forces of House Stark. Lysa refuses to participate and Catelyn leaves the Eyrie.

Season 2
House Arryn remains neutral in the War of the Five Kings, with Lady Lysa continuing to withhold her armies from leaving the Vale to aid House Stark and House Tully.

Season 3
Lysa and Robin do not attend the funeral of Hoster Tully and continue to remain at the Eyrie. Tywin Lannister sends Petyr Baelish to marry Lysa so that the Iron Throne can acquire the support of the Vale. In Baelish's absence, Tywin appoints his son Tyrion to become the new Master of Coin.

Season 4
Following the Purple Wedding, Littlefinger smuggles Sansa Stark out of King's Landing and takes her to the Eyrie, where they meet with Lysa and Robin. After privately admitting her role in the death of her husband, Lady Lysa hastily marries her childhood friend Petyr Baelish. Later, she witnesses him kissing her niece Sansa and becomes mad with jealousy. She summons Sansa to the High Hall of the Arryns, threatening to push her out the Moon Door before Petyr interrupts her. Petyr briefly manages to calm Lysa down, saying he only ever loved one woman. To Lysa's horror, he utters, "Your sister", and shoves Lysa out the Moon Door to her death. When the lords of the Vale come to investigate Lysa's death, Petyr, with Sansa's help, convinces the lords that Lysa committed suicide by jumping through the Moon Door and becomes Lord Protector of the Vale until Robin comes of age.

Season 5
Baelish leaves Robin to be fostered at Runestone under the tutelage of Lord Yohn Royce, who assures Baelish of the boy's safety but makes no promises that he will become a better swordsman.

In King's Landing, Baelish gains House Lannister's blessings for a plan to use the knights of the Vale to invade The North and reclaim it for the Iron Throne.

Season 6
Petyr Baelish convinces Robin Arryn to use the knights of the Vale to help save his cousin, Sansa Stark, who is being hunted by House Bolton after escaping the clutches of Ramsay Bolton. Baelish also blackmails Yohn Royce into absolute loyalty in a display of influence that Baelish holds over the young and easily manipulated Defender of the Vale. The Arryn troops camp at Moat Cailin while Baelish travels north to offer his assistance to Sansa. Though she initially denies his help, she later sends a raven to Baelish requesting for the support of the Arryn soldiers.

When the Stark loyalist army seems to be on the verge of absolute annihilation at the Battle of the Bastards, the knights of the Vale arrive at the command of Petyr Baelish and Sansa Stark. They proceed to wipe out the Bolton troops surrounding the Stark forces, helping the Starks take back Winterfell from House Bolton in defiance of the Iron Throne. Baelish subsequently declares House Arryn's support for House Stark, and the Vale lords join the Northern lords in declaring Jon Snow the King in the North. This officially brings to an end the policy of neutrality that House Arryn has held during the War of the Five Kings.

Season 7
Lord Yohn Royce and Petyr Baelish remain in Winterfell as representatives of House Arryn to House Stark. When Jon receives an invitation from Tyrion Lannister about meeting Daenerys Targaryen and Samwell Tarly's letter about large amount of dragonglass located at Dragonstone, Yohn Royce is against Jon's decision to meet her, claiming that a Targaryen cannot be trusted. Despite this Jon leaves for Dragonstone, leaving Sansa as the acting regent of the North and Lady of Winterfell.

When Arya Stark returns to Winterfell, Littlefinger manipulates the Stark sisters to fight against each other, with Arya suspecting that Sansa intends to become ruler of the North. Yohn Royce also claims that Sansa should do it, since Jon has left, but Sansa defends his choice. When Sansa receives the word that Jon has bent the knee to Daenerys Targaryen, Littlefinger suggests that Jon should be removed as King in the North. Finally, Sansa learns about Littlefinger's crimes against House Stark and House Arryn, putting him on a surprise trial in which he is charged of murdering both Jon Arryn and Lysa Arryn and betraying Ned Stark. Yohn Royce refuses to escort Littlefinger back to the Eyrie because of his crimes against House Arryn and he is subsequently executed by Arya on Sansa's orders. With Littlefinger dead, and Jon pledging the North to Daenerys Targaryen, House Arryn has also become a vassal for House Targaryen.

Military
House Arryn commanded a formidable military prior to the outbreak of the War of the Five Kings. It was able to field over 20,000 men, due to Lysa Arryn's decision to remain neutral. The Arryns are apparently well organized and well armed, as evident during the Battle of the Bastards wherein they aided the Starks in reclaiming their ancestral seat of Winterfell, defeating the Bolton phalanx with ease. The knights of the Vale are also capable of battling in the ice and snow due to the Vale's many altitudes, ranging from high to low ranges. Their house is wealthy due to trade and fertility from port-towns such as Gulltown, so the Arryn army is well-equipped compared to the Freys or the Starks. They carry circular shields emblazoned with House Arryn's moon-and-falcon sigil. Arryn soldiers wear silver armor with blue cloaks.

In the books
In the A Song of Ice and Fire novels, House Arryn is the oldest and purest line of Andal nobility. According to tradition, the Andals landed on the Fingers, an area of peninsulas, hills, and rivers on Westeros's eastern coast, six thousand years ago and helped conquer the Vale. Ser Artys Arryn's duel with the Griffin King is said to have taken place on the shoulder of the Giant's Lance where the Arryns later built the Eyrie.

During the Targaryen conquest, the Arryns planned to make a stand at the Bloody Gate, the only pass into the Vale, and gathered their armies there while the King of the Vale (also a young boy at this time) and his mother, the regent, took refuge in the Eyrie. Rather than risking a bloody battle, Visenya Targaryen simply flew her dragon Vhagar to the Vale and landed in the courtyard while the young king was at play. The king agreed to swear fealty to Aegon the Conqueror if Visenya allowed him to ride on Vhagar. She agreed, the bargain was upheld and the Arryns and their vassals became loyal subjects of the Targaryens.

During the summer they rule over the Vale from the Eyrie, but during the winter they descend to the Gates of the Moon, a castle at the foot of the mountain. The Gates of the Moon have not appeared in the television adaptation and the House Arryn is depicted residing at the Eyrie in winter.

Jon Arryn and Lysa Tully's son is called "Robert", not "Robin", in the books. This change was made to prevent confusion with Robert Baratheon or Robb Stark. George R.R. Martin approved this change, noting that Robert Arryn's nickname in the books, "Sweetrobin", remains intact.

In the books, the Heraldry of House Arryn is specifically sky blue, but in the TV series it is simply blue (azure), like House Tully's heraldry. The Coat of arms is also a little different: a sky-blue falcon soaring against a white moon, on a sky-blue field.

The members of the House Arryn in the books are:
 * Lord Jon Arryn, the former head of the family, now deceased.
 * His first wife, Lady Jeyne Arryn, who died in childbirth. Their daughter was stillborn.
 * His second wife, Lady Rowena Arryn, who died of a chill.
 * His third and current wife, Lady Lysa, of House Tully. Currently the ruling lady of the Vale until her son comes of age.
 * Lord Jon's only surviving child and heir, Robert Arryn, the Lord of the Vale.
 * Lord Jon's younger sister, Lady Alys, married into House Waynwood.
 * Alys's eldest son, Ser Denys Arryn, killed during Robert's Rebellion.
 * Alys's grandson by her daughter and Robert's heir (unless he has a son), Harrold Hardyng.
 * Lord Jon's youngest and deceased brother, Ser Ronnel Arryn.
 * Ser Ronnel's son, Ser Elbert Arryn, formerly Lord Jon's heir, slain at the order of the Mad King before the rebellion.

The following sworn houses have yet to appear in the series:
 * House Belmore of Strongsong
