The Torentine or Torrentine is a river in Dorne which flows south from the western Red Mountains to the Summer Sea. The castles of Blackmont, High Hermitage, and Starfall are located on the Torentine. It is formed by the confluence of two rivers near Blackmont. It is a fast river which passes through a series of rapids, waterfalls, canyons, and crevasses.
The founder of House Dayne is said to have raised Starfall on an island at the river's mouth, having tracked a falling star there. The Daynes ruled as Kings of the Torrentine from the days of the First Men until the defeat of King Vorian Dayne in Nymeria's War.
