I'm another one who would like to know more about the area around the Sea of Rhun. If there was commercial traffic on the River Running, there had to be someone at the other end! Those wines of Dorwinion, for example: what was Dorwinion like? Who lived there, elves or men? What kind of culture did they belong to? Were they akin to the Lake-men and the men of Dale, or were they of Easterling stock, or were they akin to the forefathers of the Rohirrim?
