River of Souls

The River of Souls is a river featured in the Gate of Pain mission in the Realm of Torment. The river is colored purple, and as the name suggests, is filled with souls.

The River appears to flow through the Domain of Pain, where the Tortureweb Dryders harvest souls before the Gate of Pain mission. The river then flows into Nightfallen Jahai, where it follows the route of the Elon in Jahai Bluffs
