The Shores of Dallamar
Gren Dallam is (or was) a Carthagian sea captain who discovered Dallamar. While daring to venture further and further from Vesseroth he was fortunate to see Mount Bora on a rare clear day. He found nearby Atrynn Bay and made landfall near the present location of Ossinerak.
Gren Dallam made several subsequent trips back and forth between Vesseroth and the land now known as Dallamar. Four years ago he left with six ships intent upon sailing around the southern edge of the continent. He did not return from that voyage, and is presumed to be dead.
