Barca was busy with all of Luria between us and Poraytown and then being beaten up by Luria. If we'd known you could still buy duchies maybe we should have bought Sun Hall. Barca also had closesr ties to D'Hara and Fissoa than it did Morek. I doubt moving to Poraytown would have changed much, although that would have been neat.
I tried asking Ambassador Seoras that if he really was so upset about us being in Sun Hall we'd take Poraytown instead and happily make peace, but he had no useful reply to that.
