A Storm of Sails

From the introduction: Face the Mazin Armada The slavers of Mazin prepare to invade Freeport. These div-led people of elemental blood sail from a city far to the south, too far away for Freeport’s pirate fleet to reach Mazin itself when the cities were at war long ago. Now seeking revenge for their defeat in that ancient conflict, a Mazini fleet sails to establish a supply port in Hangnail and then sail on to conquer Freeport and enslave all survivors in both ports.
