I would strongly prefer land near the coast, as the whole RP history of the 2 noble bloodlines I will play revolves around one being a much more recent arrival from an exotic middle-eastish culture across the sea (significance given to the motif of seas and rivers), also some number of settlements to grow into as there are quite a few characters lined up for roleplaying. I think lands northeast of D (where the ocean meets the river) looks like exactly what I had in mind, or are the marked areas the only ones made available ? Obviously putting some thought into balance and all that.
