Vyalldehun River

The frigid Vyalldehun River is about 160 miles long and rises in the Linnorm Kingdom of the Thanelands in the Lands of the Linnorm Kings. It flows west for over fifty miles, at which point the river turns to the south-west and meanders the rest of its course as the border between the Thanelands and Icemark. Finally, it becomes a tributary of the Whitegold River south of the Moundlands.

The river is named after an ancient linnorm called Vyalldehun whose lair was at Ice Spire just south of the river in the Thanelands.
