Lake Headwater is a mid-sized lake in the Highlands of the Kingdom of Kalvete. The lake sits on the Frásnúr River, where the river's source enters the lake in the east before flowing out to the west.
Lake Headwater, as well as the sections of the Frásnúr that flow in and out of it, makes the soil in the surrounding region fertile enough for limited agriculture. This has been crucial to the young Kingdom, helping to offset recent territory losses due to the Holy Empire of Acolytius.
