A cold mountain lake at the eastern limit of Istora's highlands, where the ground begins to rise toward the Dragon's Spine Coast. The Istori call it the edge of the world and mean it more or less plainly: past Thraken the land stops being theirs and starts answering to powers they do not pretend to understand. They keep no garrison on its shore. Whatever lies beyond the lake is not a thing the kingdom expects to fight, only a thing it watches, and the rangers who range that far come back with little to report beyond cold water and the sense of having been looked at in return.
