The Summermelt River rises in the Kodar Mountains in the south-east of the Lands of the Linnorm Kings in the Linnorm Kingdom of Southmoor, in which the river's course is completely contained. It travels some eighty miles north-east until it becomes a tributary of the Thundering River at the borders of the Grungir Forest.
