Within the Zerzuran Badlands, the god Speed is embodied as Alsuriea Nahr (Speed's River). It is actually a strait, connecting the Fum Alnahr and Narova Falls, ultimately feeding into the Spinning Sea.
The strait boasts tributaries and confluences extending from Alchemy Bay to the Spinning Sea. At several points the water is over a mile wide.
Most ships are unable to cross the main channel, but there are fords and bridges throughout the calmer, narrower portions, which extend into the Rhachloa Downs, feeding the many rice paddies and marshes of the Krokesteppe.
