The River Umber was a fast flowing river, full of cascades, that formed part of the natural border between Aglarond and Thesk.[citation needed]

The river has its headwaters in the high glaciers of Thaymount and flowed west. At the town of Nethentir if flowed down the First Escarpment and into Lake Umber, and from there it flowed through the Dragonjaw Mountains into the Sea of Dlurg.[1]


Vessels could move up and down the river, all the way to the eastern end of Lake Umber. Thay often sent trade ships down the river into the Sea of Dlurg and onto the Sea of Fallen Stars.[1]
