Turmus:
Last major river port on the Vosk River before the Vosk Delta,
located on northern bank of the Vosk. It is the last major
river port on the Vosk before the nearly impassable marshes
of the delta.

"It had been thought, and shown
on many maps," I said, "that the subequatorial Cartius
not only flowed into Lake Ushindi, but emerged northward,
traversing the sloping western flatlands to join the Vosk
at Turmus." Turmus
was the last major river port on the Vosk before the almost
impassable marshes of the delta.
