Karhold

Karhold, the stronghold of House Karstark, stands as a grim northern fortress whose fate becomes entangled with the larger wars for the North. As a cadet branch of House Stark, the Karstarks share the direwolf’s blood but not its loyalty; during the War of the Five Kings, Lord Rickard Karstark’s execution by Robb Stark for murdering prisoners leaves the castle’s succession in chaos, a void that ambitious kin and outside powers rush to fill.

Identity and History

Karhold is the seat of House Karstark, founded centuries ago when a younger son of Winterfell was granted the lands and castle. The Karstarks have ever been proud of their Stark descent, but that pride curdled into grievance after Lord Rickard’s death. The castle itself is a stark northern holdfast, built to withstand long winters and siege alike, its walls of grey stone rising from the cold, windswept lands east of the kingsroad. By the time of the War of the Five Kings, the male line of Karhold has been decimated: Lord Rickard’s sons Torrhen and Eddard died in battle, and his heir Harrion is a captive of the Lannisters at Maidenpool. This leaves the succession in dispute between Rickard’s daughter Alys and his uncle Arnolf, the castellan.

The Succession Crisis

Alys Karstark, a girl of fifteen, is the rightful heir by the laws of the North, where a daughter comes before an uncle. But her great-uncle Arnolf, who has served as castellan since Lord Rickard marched south, has other plans. Arnolf means to seize Karhold for himself by marrying Alys to his son Cregan, a brutal man who has already buried two wives. Alys, fearing for her life and her birthright, flees Karhold and rides alone through the snow to Castle Black, seeking protection from Jon Snow, the last son of Eddard Stark she can trust. She arrives half-frozen, her horse dying beneath her, and begs Jon to save her from her uncle’s scheme. “My uncle Cregan is hard upon my trail,” she tells him. “You must not let him take me back to Karhold.”

Arnolf’s Treachery

Arnolf Karstark, meanwhile, has already cast his lot with Roose Bolton. Though he publicly declares for Stannis Baratheon, Alys reveals the truth: “Arnolf is rushing to Winterfell, ’tis true, but only so he might put his dagger in your king’s back. He cast his lot with Roose Bolton long ago… for gold, the promise of a pardon, and poor Harry’s head.” Arnolf’s feigned loyalty is a trap designed to lure Stannis into a fatal engagement, and his son Cregan pursues Alys northward to drag her back to Karhold and force the marriage that would legitimize their usurpation. Cregan and his men are intercepted by Jon Snow’s rangers and imprisoned in the ice cells of Castle Black, but the threat to Karhold remains.

Resolution and New Allegiance

Jon Snow resolves the crisis by marrying Alys to Sigorn, the Magnar of Thenn, in a ceremony conducted by Melisandre before the Wall. The marriage binds the Thenns—a powerful wildling clan—to the Karstark line and gives Alys a husband and an army to reclaim her birthright. Alys herself is pragmatic about the match: “I am now a woman wed. A wildling husband with his own little wildling army.” She intends to return to Karhold with Sigorn and his Thenn warriors, confident that the castle will open its gates to her. “Two of your men have already sworn her their service and confirmed all she had to say concerning the plans your father made with Ramsay Snow,” Jon tells Cregan. The fate of Karhold thus hangs on whether Alys and Sigorn can enforce her claim against Arnolf’s treachery and the Boltons’ power.

Narrative Significance

Karhold’s crisis illustrates the collapse of the old feudal order in the North, where the deaths of lords and heirs have left castles vulnerable to internal betrayal and external predation. The Karstark succession dispute also serves as a microcosm of the larger war: the struggle between legitimate inheritance (Alys) and ruthless ambition (Arnolf), between Stark loyalty and Bolton alliance. Jon Snow’s intervention—marrying a highborn northern girl to a wildling chief—is a radical act that redefines the political landscape of the North, creating new alliances that may prove decisive in the wars to come. Karhold itself, with its strategic position and its claim to Stark blood, remains a prize worth fighting for, and its ultimate allegiance will help determine who rules the North.
