Underground River

The entrance of the Underground River at the eastern end of Talkyra Canyon.

The Underground River is a very large river which connects the waterways of the Fifth of Trees to the Inner World.

It begins at the end of Talkyra Canyon, being initially sourced from the Talkyra Canyon river and the Northern River via Haraka Falls. It flows into unknown depths, and has additional sources throughout the eastern part of the Fifth of Trees. Some of these additional connections to the underground water network are the result of Corthan projects from its earlier history.
