T'ugü

Tʼugü is a subtropical drainage basin set into the north west corner of a continent in the southern hemisphere. The basin is about 300km across and has an area of around 40,000km² (1/750 of an Africa). It is enclosed by ~1-3km tall mountains on the eastern and southern edges. The people who live in the basin, the Öb do not know what is beyond the mountains.



Climate
The climate in the basin is fairly hot and humid with a mild monsoon in the summer. The low lying areas are particularly humid and much of the area around the river is swampy. The higher and drier land is mostly covered with subtropical evergreen forest.

Wildlife
The wildlife of Tʼugü is typical for the climate: frogs, salamanders, snakes, lizards, large ungulates, muntjacs, various mustelids, flying squirrels, some small primates (maybe orangutans?), something resembling pangolins and ~50cm giant snails. The river is home to many species of crustaceans, catfish and eels as well as many other smaller fish species.
