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.
