Maester Steven, a while back I remember you stating it was strange that there was no port city where the Mander met the sea. However, could it be the Hightowers used their influence to prevent the rise of a city that could rival Oldtown? The Manderly’s are famously good at running a port, and they take their name from the river. So, could the mouth of the river have been where Dustonbury was located, and could the Hightowers have played a role in the Manderly’s banishment?
