The Oddanroy is the largest river in the Dragon Coast. It starts from rainwater that falls onto the Dragon Heights and flows westward in valleys. It flows through the hills and low peaks of the western Dragonheights, before it flows into the larger cities of the Dragonpoint.
on top of providing water for the hills of the heights and the farms of the point, it helps facilitate trade along the length of the Dragoncoast, with several cities settled at the major confluences of the Oddanroy and its tributaries, each named after the tributary meeting the river there (The Lilroy, Sildnamm, and Sildnom).
The river ends at the city of Oddansbay, built where the Oddanroy delta flows into the Bay of Oddan. The bay is one of the only natural harbors in all of the dragoncoast, not only does it provide shelter for navies, but it is a good midpoint for ships going from Gerudia to Lencenor, and it helps facilitate the movement of goods to and from the otherwise isolated interior of the rough Deagoncoast.
