The Mistydeep River is one of the major rivers of the Elven Nations. The upper part of the river flows southwest through Old Ta'Faendryl and Ta'Vaalor, then turns south towards the river delta at Ta'Nalfein.
Rapids and waterfalls on the upper Mistydeep make it unsuitable for water-based travel over long distances. A bridge over the river was once built along the Aradhul Road between Ta'Faendryl and Ta'Vaalor, but it has since fallen into disrepair.
The town of Ravelin is situated a short distance upstream from Ta'Vaalor. Adventurers can requisition rowboats from Ravelin to explore the portion of the river between Ravelin and Ta'Vaalor, which includes a hunting ground at Sorcerer's Isle.
