The Andals brought the Seven with them from across the narrow sea (I: 432)
When the Andals crossed the narrow sea and swept away the kingdoms of the First Men, the sons of fallen kings held to their vows in the Night's Watch (I: 553)
The Andals were the first new invaders after the First Men had settled their peace with the Children and lived in harmony with them for 4,000 years. They were tall and fair-haired warriors who carried steel weapons and the seven-pointed star of the new gods painted on their bodies. This was at least 6,000 years ago (I: 361, 617-618)
The wars between the First Men and the Andals lasted hundreds of years, but eventually the six southron realms fell to them. Only the Kings of Winter remained in the North (I: 618)
The Andals burned out all the weirwood groves, hacked down the faces, and slew the children when they found them (I: 618)
The Brackens and the Blackwoods have been feuding for thousands of years, from the time of the Age of Heroes when they were rivals as kings over the riverlands at various points in time. Matters were not helped when the Brackens abandoned the old gods in favor of the Seven (I: 662. THK: 43. SSM: 1)
The Andals came some 4,000 years ago to the Iron Islands (I: 688. II: 137)
The trial of seven is seldom used, coming across with the Andals and their seven gods. The Andals believed that if seven champions fought on each side, the gods thus honored would be more likely to see justice done. If a man cannot find six others to stand with him, then he is obviously guilty (THK: 509)
If the accused is killed in a trial of seven, it is believed that the gods have judged him guilty and the contest then ends. If his accusers are slain or withdraw their accusations, the contest ends and he is decreed innocent. Otherwise, all seven of one side must die or yield for the trial to end (THK: 521)
The smallfolk shun High Heart, saying it was haunted by ghosts of the children who had died there when the Andal king Erreg the Kinslayer had cut down the grove (III: 249)
Tristifer, the Fourth of his Name, King of the Rivers and the Hills, ruled from the Trident to the Neck thousands of years before Jenny of Oldstones and her prince, in the days when the kingdoms of the First Men were falling one after the other before the Andals. He was called the Hammer of Justice, and the singers say that he fought a hundred battles and won nine-and-ninety. When he raised his castle, now a ruin known only as Oldstones, it was the strongest in Westeros (III: 520)
Tristifer IV was killed in his hundredth battle, when seven Andal kings joined forces against him. His son, Tristifer V, was not his equal, and soon the realm was lost, and the castle, and then the line. With Tristifer V died House Mudd, that had ruled the riverlands for a thousand years before the Andals came (III: 520)
Legend says that it was at the Nightfort where the Rat Cook served the Andal king his prince-and-bacon pie (III: 624)
The legend has it that the Rat Cook had cooked the son of the Andal king in a big pie with onions, carrots, mushrooms, lots of pepper and salt, a rasher of bacon, and a dark red Dornish wine. Then he served him to his father, who praised the taste and had a second slice. Afterward the gods transformed the cook into a monstrous white rat who could only eat his own young. He roamed the Nightfort ever since, devouring his children, but still his hunger was not sated. The moral of the story is that the gods did not curse him for his murder or for his serving the Andal king his son in a pie, for a man has a right to vengeance, but he was cursed for slaying a guest beneath his roof and that the gods cannot forgive (III: 631)
The Fingers were one of the places where the Andals first landed, to wrest the Vale from the First Men (III: 770)
In ancient days, wrongful deaths could be addressed by the paying of a blood price, and in the Age of Heroes a man's life might be reckoned at being worth no more than a sack of silver (TSS: 104, 126)
When the Andals first invaded Westeros, some of their warriors had the seven-pointed star of the Faith carved into their flesh (IV: 63)
The oldest histories in Westeros were written after the Andal's came to Westeros, because the First Men only used runes for carving on stone. Everything written about the Age of Heroes, the Dawn Age, and the Long Night originates from stories written down by septons thousands of years later. There are archmaesters who question all these histories, noting the kings who seem to live for centuries and knights who fought a thousand years before there were knights (IV: 80)
The Darklyns were petty kings before the Andals came, during the Age of Heroes (IV: 133)
The blood of the First Men runs strong in Crackclaw Point, as the inhabitants fought off the Andals but eventually accepted Andal brides (IV: 282)
Legends claim that the Winged Knight, Ser Artys Arryn, drove the First Men from the Vale and fle to the top of the Giant’s Lance on a huge falcon to slay the Griffin King. There are hundreds of stories about his adventures (IV: 150, 606)
Andalos, the ancestral land of the Andals, lies to the east of Pentos. It is said the Andals took it from the hairy men who were there before men, cousins to the Ibbense. The heart of that realm lies to the northeast of Pentos, but the southern regions are known as the Flatlands in Pentos (V: 79)
The Faith teaches that the Seven once walked in Andalos in human form (V: 79)
Further east beyond the Flatlands lie the Velvet Hills (V: 79)
Andalos is said to have been the realm of Hugor of the Hill, and the Faith teaches in The Seven-Pointed Star that the Seven themselves crowned him with a glowing crown made of stars (V: 79, 80)
The Seven-Pointed Star refers to the Smith making suits of iron plates for the sons of Hugor of the Hill. It is claimed in Essos that the Andals learned iron-working from the Rhoynar who dwelt along the river (V: 80)
There exists an ancient melee format which uses seven teams (SSM: 1)
Maps still mark out the lands of the Andals on the eastern continent, but the area has seen so many invasions and migrations that very little of the Andal people remains there (SSM: 1)
