The White Knife has its headwaters in two streams which join just south of Long Lake and the Lonely Hills. It then flows south, with Winterfell to the west and the Dreadfort and Hornwood to the east. Just south of Winterfell, a tributary of the White Knife begins in the southeastern stretch of the wolfswood and flows southeast to meet the White Knife west of the Sheepshead Hills; Castle Cerwyn is located along this tributary. The White Knife continues south to meet the Bite at White Harbor.
River runners are long and lean boats used to traverse the swift currents and rocky shoots of the White Knife. Hides and timber from the north are brought down the river for trade in White Harbor. Lord Wyman Manderly counts Warden of the White Knife among his titles. There is ice fishing on the northern rivers.
King Jon Stark had the Wolf's Den built to defend the mouth of the White Knife. House Arryn sailed up the river when they captured the Wolf's Den during the War Across the Water. King Brandon Stark reclaimed the Wolf's Den from slavers from the Stepstones when the White Knife froze during a particularly harsh winter.
Approximately one thousand years before the War of Conquest, House Manderly received the Wolf's Den and land at the mouth of the White Knife from House Stark, which they developed into the city of White Harbor.
