Vehicle: Sea Fort

Enormous masses of steel kept afloat by magic, sea forts were originally developed by the Corentyn armada to enforce blockades. While not particularly fast or maneuverable, their high resistance to damage and ability to expand their reach with additional walls makes them difficult to ignore. Armadas often keep them anchored to shield a narrow channel or vulnerable land target or use them to shield smaller and nimbler craft as they prepare an attack.
