Natzu River

The Natzu River is a river in Tarm Woods, Spool Swamp, Holodrum, and the Eragou Mountain Range.

Geography
The Natzu River flows northwest from its source at the Tarm Ruins, through Tarm Woods and draining into Spool Swamp, and flowing down through the western Eragou Mountain Range before emptying into the Umoloth near Greshou. The river is known for its dangerous flooding, which has claimed at least one attempt at settlement.

History
Circa 5500 BG, Ocean Zora from the Umoloth settled the eastern Coast of Airu and colonized upstream the Natzu River, eventually settling Spool Swamp by 5000 BG. Many thousands of years later, Horonians attempted to establish a settlement along its banks, which was forced to be abandoned due to destructive flooding. Even the name of the waterlogged ruins has been forgotten, and it now serves as the de - facto capital of the River Zora. The river is the main highway of Zola raids against the Dominion Valley and Lanayru Province.
