On the new map, the Drowned Merchant River splits in two at Toshi Ranbo – one branch following its usual course to the west, the other to the southeast, past the Castle of the Emerald Champion (and, quite possibly, if you squint, past Otosan Uchi and Slow Tide Harbor. Yet surely both branches, flowing in opposite directions, towards opposite outlets, don't have the same name.
Anyone have any idea what this new, second Drowned Merchant River is called?
