Brondeng River (Yeosak)
The southernmost and largest of the four chief rivers in the Yesan Reach, itself part of the Yeosak Sunmire.
In addition to hosting a vibrant fish population, the Brondeng is a vital means of carrying foodstuffs from the Shirwood along the Yesan Reach into the Yedon Peninsula and south into the Kangdun Mire.
