ArrynHouse 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.
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.
"As High As Honor"
BaratheonHouse Baratheon of Storm's End is an extinct Great House of Westeros. Its main branch was formerly the royal house, but House Lannister now controls the throne.
The ancestral Baratheon stronghold is Storm's End, but since becoming the royal house, they have also taken possession of the old Targaryen island fortress of Dragonstone, while the King rules from the city of King's Landing, the capital of the Seven Kingdoms.
When the War of the Five Kings began following King Robert Baratheon's death, House Baratheon became divided into three distinct factions: one led by Robert's alleged son (who is actually the product of an incestuous relationship between Queen Cersei and Ser Jaime Lannister), Joffrey; one led by his younger brother, Stannis; and one led by his youngest brother, Renly. As a result of Renly's murder and the casualties suffered at the Battle of the Blackwater, the majority of House Baratheon's surviving lords and bannermen are now sworn to Stannis, though much of the Stormlands are occupied by Lannister and Tyrell forces loyal to King Tommen Baratheon, Joffrey's younger brother and successor.
With Tommen's death, House Baratheon has become legally extinct.
The only remaining known member of the Baratheon bloodline is Gendry, King Robert's unacknowledged bastard son.
"Ours Is The Fury"
GreyjoyHouse Greyjoy of Pyke is one of the Great Houses of Westeros. It rules over the Iron Islands, a harsh and bleak collection of islands off the west coast of Westeros, from the castle at Pyke. The head of the house is the Lord Reaper of Pyke.
House Greyjoy has been in open rebellion against the Iron Throne since the War of the Five Kings, during which it sought independence for the Iron Islands once more. However, following the death of King Balon Greyjoy and the election of his brother, Euron, as the new King of the Iron Islands, House Greyjoy has been divided between Euron and his followers, and Balon's surviving children, Yara and Theon, and their followers.
"We Do Not Sow"
LannisterHouse Lannister of Casterly Rock is one of the Great Houses of Westeros, one of its richest and most powerful families and oldest dynasties. It is also the current royal house of the Seven Kingdoms following the extinction of House Baratheon of King's Landing.
Their lands are in the far west of the continent. Their seat is Casterly Rock, a massive rocky promontory overlooking the Sunset Sea which has had habitations and fortifications built into it over the millennia. They are the Lords Paramount of the Westerlands and Wardens of the West. As the new royal house, they also rule directly over the Crownlands from their seat of the Red Keep in King's Landing, the traditional seat of the royal family.
The incestuous relationship of Cersei and Jaime has been concealed in a conspiracy. Their son Joffrey Baratheon has claimed the Iron Throne on the premise that he was actually fathered by the late King Robert Baratheon. Lord Tywin was a key supporter of his reign in the War of the Five Kings.
"Hear Me Roar!"
MartellHouse Martell of Sunspear is a legally extinct Great House of Westeros. It ruled the peninsula of Dorne in the far south of the continent from their castle Sunspear. Though loyal to the Iron Throne, the Martells were never conquered by the Targaryens and pursued a more isolated role in wider political events since Robert's Rebellion.
With the assassinations of Prince Doran Martell and his only heir, Prince Trystane, by Ellaria Sand and the Sand Snakes, House Martell is legally extinct, although the Sand Snakes themselves carry Martell blood through their father Oberyn. The Sand Snakes also continue to use the Martell sigil to represent themselves and Dorne. Under the leadership of Ellaria Sand and the Sand Snakes, the forces of House Martell and Dorne have aligned to support the cause of Daenerys Targaryen, against House Lannister after they declared war against them.
"Unbowed, Unbent, Unbroken"
StarkHouse Stark of Winterfell is a Great House of Westeros, ruling over the vast region known as the North and the Vale as Kings in the North from their seat in Winterfell, recently retaken by the Starks from House Bolton. It is by far one of the oldest lines of Westerosi nobility, claiming a line of descent stretching back over eight thousand years. The head of the house is the Lord of Winterfell. Before the Targaryen conquest, the leaders of House Stark ruled over the region as the Kings in the North. Jon Snow is the current King in the North and the Vale, partially due to the allegiance of Petyr Baelish, the Lord Regent of the Vale, to House Stark.
Their rule in the North seemingly ended after the events of the Red Wedding when House Frey and House Bolton betrayed them, after joining alliance with House Lannister. Roose Bolton personally killed King Robb Stark. Both the North and Winterfell were taken over by House Bolton, but their hold was jeopardized when Sansa Stark escaped their clutches after learning that her brothers Bran and Rickon Stark were still alive. House Stark were restored to their former stature after the Battle of the Bastards albeit at great cost with Rickon's death. Their success in this battle later leads to the resurgence of House Stark as the royal family of the North, with its vassals declaring Jon Snow as King in the North.
"Winter is Coming"
TargaryenHouse Targaryen is a former Great House of Westeros and was the ruling royal House of the Seven Kingdoms for three centuries, before it was deposed during Robert's Rebellion and House Baratheon replaced it as the new royal House. The few surviving Targaryens fled into exile. Currently based in Essos, House Targaryen seeks to retake the Seven Kingdoms from House Lannister.
"Fire And Blood"
TullyHouse Tully of Riverrun is an exiled Great House of Westeros. Its most senior member carried the title of Lord of Riverrun and Lord Paramount of the Trident, until the Red Wedding. The current head is Lord Edmure Tully, son of the late Hoster Tully.
At the onset of the War of the Five Kings, House Tully came under attack by House Lannister and lent its support for House Stark when they came to their aid in the liberation of the Riverlands. House Tully has since been formally stripped of lands and titles for rebellion against the Iron Throne, with Lord Edmure a captive of House Frey following the Red Wedding.
Later, Ser Brynden Tully gathered the remaining Tully forces and reclaimed Riverrun from the Freys, reopening conflict between the Tullys and the Iron Throne. The Freys lay siege to Riverrun, and were later assisted by the Lannisters on the orders of King Tommen I. Ser Jaime Lannister managed to end the siege by convincing Edmure Tully to command the garrison to lay down their weapons in return for clemency and protection. Brynden was killed during a final stand with Lannister and Frey forces while Edmure was returned to the Freys as a prisoner.
"Family, Duty, Honor"
TyrellHouse Tyrell of Highgarden is one of the Great Houses of Westeros. It rules over the Reach, a vast, fertile, and heavily-populated region of southwestern Westeros, from their castle-seat, Highgarden.
Formerly led by Lord Mace Tyrell, his mother, the indomitable Olenna Tyrell, stands as the last known member of the house. Mace's son Loras was a noted tournament knight (and, secretly, the lover of Lord Renly Baratheon). Mace's daughter Margaery married Renly when he crowned himself king, to cement the alliance between Renly and her father. Following Renly's death, Margaery was then married to King Joffrey Baratheon before his assassination at his wedding feast. She was then married to his younger brother, King Tommen Baratheon. Olenna Tyrell assumed House Tyrell's lordship as Margaery Tyrell, Loras Tyrell, and Mace Tyrell were killed by wildfire by at the destruction of the Great Sept of Baelor. Under Lady Olenna, who has served as the head of the house since, House Tyrell has aligned itself with House Targaryen in opposition against Queen Cersei I for orchestrating the demise of most of the main branch of the Tyrell family.
BaelishHouse Baelish of Baelish Keep was formerly a lesser vassal house that held fealty to House Arryn of the Vale. They are now the Lords of Harrenhal.
Petyr Baelish, called "Littlefinger", is the only member of the House.
"Knowledge Is Power"
BoltonHouse Bolton of the Dreadfort is an extinct noble house from the North. After the Red Wedding, they were the Great House of the North, having usurped their position from their former liege lords, House Stark. Their original lands were in the northeast of the Stark territories. Their stronghold was a castle called the Dreadfort and the head of the house was the Lord of the Dreadfort.
House Bolton was infamous for its centuries-old practice of flaying their enemies alive, to the point that they used a flayed man as their House sigil. The Boltons supposedly gave up this practice after bending the knee to House Stark, and centuries later Lord Eddard Stark outlawed flaying in the North altogether, but the Boltons continued the practice. This resulted in them being despised and feared by many of the Northern houses, especially after their betrayal of House Stark and their torching of Winterfell.
Shortly before the Battle of the Bastards, Lord Ramsay Bolton murdered his father, Lord Roose Bolton, taking his father's titles and ranks. In the aftermath of the battle, Ramsay was executed by the Starks; with no heir to follow him, House Bolton has officially become extinct.
"Our Blades Are Sharp"
CleganeHouse Clegane of Clegane's Keep is a vassal house that holds fealty to House Lannister of Casterly Rock. Their lands are southeast of Casterly Rock and consist of a small patch of land and a modest house. They are landed knights rather than a full noble house, but have strong ties to the Lannisters.
The former head of the family is Ser Gregor Clegane, known as "The Mountain That Rides", who has since been named to the Kingsguard. Gregor's younger brother, Sandor Clegane, known as "The Hound", is the rightful lord of House Clegane, but is believed dead.
The three dogs in the sigil signify the three dogs that died fighting off the lioness that attacked Tytos Lannister.
"A Hound Will Never Lie To You"
FreyHouse Frey of the Twins is a noble house from the Riverlands. They are currently the Great House of the Riverlands, having gained their position for their treachery against their former liege lords, House Tully, who were stripped of all their lands and titles for their rebellion against the Iron Throne; House Tully had supported the independence movement for the Kingdom of the North. The current head of the house is unknown following the assassinations of Lord Walder Frey and two of his sons, Lothar Frey and Walder Rivers, by the vengeful Arya Stark.
Their ancestral seat is known as the Twins for its two identical keeps on both sides of a river linked by a bridge, sometimes called the Stone Bridge. The Twins is one of the primary crossings over the Green Fork of the Trident River, and tolls from bridge crossings have made the Freys quite wealthy fairly quickly, elevating them from obscurity six centuries ago to being one of the most powerful noble houses in the Riverlands - though they are looked down upon by older aristocratic families.
"We Stand Together"
TarthHouse Tarth of Evenfall Hall is a vassal house that holds fealty to House Baratheon of Storm's End. The family controls the island of Tarth, which lies in the Narrow Sea just off the coast of the Stormlands. Their seat is called Evenfall Hall.
House Tarth is ruled by Lord Selwyn Tarth, a widower. His sole surviving child and heir is Brienne, whom he dotes on. Brienne, a tall and broad-shouldered woman, prefers the lifestyle of a warrior to that of a typical daughter of a noble house, and is skilled at arms.
