Terramort Isle was located in the far northwestern sea. It was the home of Gabool the Wild and his corsairs, as well as the location of Fort Bladegirt. A particularly unique feature of the island was the fact that it was crisscrossed by hundreds of tunnels, a characteristic utilized by the Trag. It was presumably fully abandoned after the defeat of Gabool and his searat army, with Bladegirt being gutted by Trag and Rawnblade Widestripe.
