Guns of the Narrow Sea

War looms over the continent. The Karsund Narrows form a tight maritime choke point—barely navigable by capital ships—leading directly to the heart of the neutral coastal nation of Valdyr. Any fleet that controls the Narrows can reach the capital within hours. Unlike many nations, Valdyr did not neglect its coastal defenses. During the uneasy years before the war, Fort Blackstone was quietly transformed into one of the most advanced coastal fortresses of its time—a fusion of heavy guns, underwater weapons, early-warning systems, and hardened command facilities. Officially, the fort exists to deter smuggling and enforce neutrality. In reality, it was built for a single purpose: To stop an invasion cold. This scenario is loosely based on the Battle of Drøbak Narrows where Norwegian forces engaged a german invasion force during the early stages of the invasion of Norway. Please let me know if you think any imporvements can be made. Token count is heavy so this is likely a premium scenario.
