House Tully
Lords of Riverrun and Lords Paramount of the Trident, raised to rule the fertile, much-fought-over Riverlands after Aegon's Conquest. A silver trout leaping on a field of red and blue, the Tullys are known for binding themselves to greater houses through marriage ÔÇö and for their words, which name what they hold dearest.
The fuller tale
Where the Starks and the Baratheons won their thrones by the sword, the Tullys won theirs by good timing and a well-placed bow. Edmyn Tully was among the very first riverlords to bend the knee when Aegon's dragons crossed the narrow sea, sparing the Trident the slaughter other kingdoms endured for their resistance, and Aegon rewarded the wager by raising the Tullys from mere lords of Riverrun to Lords Paramount over a river country that had never had a single ruling house before. It made them new money by Westerosi standards and permanently suspect to prouder neighbors ÔÇö the Riverlands' bannermen swear fealty to a family whose whole claim to seniority is a single well-timed act of loyalty, not a thousand years of conquest.
Riverrun sits at the fork of the Tumblestone and the Red Fork, defended less by walls than by geography ÔÇö a castle that can flood its own approaches at need, in a country with no mountains, deserts or coastline to hide behind. Rivers run through the Riverlands and armies run along rivers, which has made the Tullys' lands the most fought-over ground in Westeros for every war the realm has managed to have, theirs or otherwise. Their answer to a country with no natural defenses was never to build higher walls; it was to marry outward as far and as often as possible, until Tully blood ran through half the great houses of the realm and an attack on any one of them risked becoming, by marriage, a family matter.
That strategy is also the family's motto made policy: Family, Duty, Honor, in that specific order, a hierarchy Hoster Tully enforced on his own children with the same rigor he applied to treaties. Catelyn went north to marry a Stark, Lysa east to marry an Arryn, and both matches bought Riverrun the swords it needed for Robert's Rebellion ÔÇö a wedding-day alliance that helped end one dynasty and, a generation later, drag the Tullys' own into a war that very nearly finished them. The silver trout on red and blue was built to represent abundance and constancy; it has spent most of the story's timeline representing a family perpetually paying interest on its own marriages.
The Red Wedding is the bill arriving all at once. Catelyn dies at a wedding meant to honor a Tully-brokered peace, in a hall flying colors her own family had vouched for; Riverrun itself changes hands between Freys and Lannisters and Tullys again before the war ends, and the family that built its whole survival strategy on alliance discovers, at the worst possible moment, exactly how little an alliance is worth once the men who swore it are dead. What is left afterward is not extinction but attrition ÔÇö a castle held by a stubborn old soldier out of pure spite, a reluctant heir doing penance he never earned, and a house that outlives the disaster mostly by being too small and too poor to be worth finishing off.
The page and the screen
The two tellings diverge sharply on how the last defiant Tully leaves the story. The show has Brynden Tully ÔÇö the Blackfish ÔÇö die fighting in the halls of Riverrun after its garrison surrenders around him, sword in hand, the ending his whole career seemed to be pointing toward. The published books decline to grant him that closure: when Riverrun's garrison yields, the Blackfish is simply not among the prisoners, having slipped out beneath a water gate and vanished into the riverlands entirely. As of the last published volume he remains unaccounted for ÔÇö the rare character whose fate the show settled with a death scene the books have pointedly left open.
