Eldest trueborn son of Lord Eddard Stark and Lady Catelyn Tully, born at Riverrun in 283 AC while his father warred in the south. Came of age at Winterfell as heir to the North, raised to the bow, the sword, and his lord father's quiet way of ruling, with a grey direwolf pup he named Grey Wind at his heel. When Lord Eddard rode south as Hand of the King in 298 AC, Robb was left as castellan of Winterfell at fourteen with Maester Luwin and Theon Greyjoy at his side, his brother Bran broken in the bed of the broken tower, his mother riding for the south on a hidden errand of her own.
Word of his father's arrest in the Red Keep brought him to call the banners. At Moat Cailin he gathered the strength of the North and crossed the Neck to the Twins, where his lady mother bought him passage of Lord Walder Frey with a pact: a Stark son to a Frey daughter, and his uncle Edmure to another, when the war was done. Splitting his host, he sent Lord Roose Bolton's foot south down the kingsroad and led the horse himself through the riverlands. In the Whispering Wood he and his lords fell upon Ser Jaime Lannister's siege of Riverrun by night, took the Kingslayer captive with Grey Wind tearing through his guard, and broke the Lannisters before the castle walls; at the Green Fork Lord Bolton bled the larger Lannister host under Lord Tywin himself. With word of Lord Eddard's death on the steps of the Great Sept of Baelor, the river-lords and northmen at Riverrun proclaimed Robb King in the North and King of the Trident, the Greatjon Umber the first to lay his sword at his feet. The boy king carried the war west, putting Ser Stafford Lannister's host to the sword at Oxcross and harrying the coasts of the westerlands to draw Lord Tywin from the Trident.
At the storming of the Crag he took a wound and was tended by Lady Jeyne Westerling, whose comfort, in the same hours that false word came that Bran and Rickon had been butchered at Winterfell by Theon Greyjoy, brought him to her bed and to a hasty wedding to spare her name. The broken pact cost him the Twins: Lord Walder Frey would not forgive the slight, and made common cause in secret with Lord Tywin and with Lord Roose Bolton, who had long since tired of his king. To mend the breach Robb offered his uncle Edmure to the Frey table in his place, and rode to the Twins for the bedding feast of Edmure Tully and Roslin Frey. When the musicians struck up The Rains of Castamere the gates were barred and the slaughter began; the Young Wolf took crossbow bolts through his body before Lord Roose drew a dagger and ran him through, saying Jaime Lannister sends his regards, and his lady mother's throat was opened where she stood beside him. His corpse was paraded with the head of Grey Wind sewn upon its shoulders in mockery of the crown, and the war he had won on every field was lost in a single hall, the Red Wedding of 299 AC.
