Tenebrous Landing

From gronkfinder

Tenebrous Landing is a port within the Blacksand Archipelago under the informal control of the pirate factions of the Blacksand League. A permanent thick fog covers the bay in which the port is located, created by ancient magical contraptions that lie beneath the water. The inhabitants of the city use the fog for defense, as any arriving hostile ships can be intercepted and boarded without before they even know who attacked them.
