The grand furious torrent that cuts across the heart of Rhondol, its main body is hungrily fed by all the other arteries that run across the mainland, growing to half a mile wide at its largest.
It is infamous for its treacherous waters, who become turbulent even with no tide or earthquake affecting them… although some say the river itself causes earthquakes upstream, by cracking open the rock of its upper falls, so it can creates waves to devour those downstream.
The Att is the major waterway in central Rhondol, connecting the coast of the Biting Sea to the Gaping Portal and the recently revealed Furyoth Dell, whose rivers feed directly into it.
