The River Umber
Born in the Thaymount’s high glaciers, the River Umber is a
steep, swift torrent with many cascades in the first hundred
miles of its length. At Nethentir, it spills out from its rapids
along the First Escarpment into the placid waters of Lake
Umber. From Lake Umber, the river is navigable all the way
to the Sea of Dlurg, passing through a broad gap in the
Dragonjaw Mountains.
Vessels cannot ascend the Umber past Nethentir, but from
the twin towns on the lake, vessels regularly carry Thayan
grain, fruit, and timber out to the Sea of Fallen Stars. The
Aglarondans at Emmech grudgingly allow Thayan cargo vessels
to pass unless Aglarond and Thay are at war, which has
not been the case for several years now.
