Naval Outposts IN#3 and IN#4 are the forts on the points that control the harbor mouth leading into East Harbor from the Dargonesti Sound. In addition to significant artillery batteries, they are the bases for dedicated harbor patrol vessels, both of the fast interceptor variety and mobile artillery platforms.
IN#4 is the smaller fort on the Northern point of the Harbor mouth, and has significant landward defenses.
