The Mansh'ii River is the second largest river on the planet of Gaban. It is the river that is the main source to the Tellawow River. The Mansh'ii is considered the busiest river as it is located near the city of Key West the most populous city on the planet.
The river formed around 5 million years ago, during a ice age that covered much of the central Tellawow Volcanic Plateau. Here the river gets it's water from glaciers that still remain as well as lake Titicaca which is considered to be the highest lake on the planet.
The river happens to be much wider than the Tellawow river, which allows much larger cargo ships to go up and down the Mansh'ii. The River has an estimated 50 billion tons of cargo crossing it's flow area every day.
