Lubber's Lurk

From PathfinderWiki

Lubber's Lurk is a cavern that serves as the only land passage that allows access to the main districts of the pirate city of Port Peril. Most people visiting Port Peril come by sea and even those who arrive overland, from the mainland or the Mwangi Expanse, normally take a ferry into the city, Lubber's Lurk is the reason why. A treacherous series of sea caves, Lubber's Lurk provides land passage but is poorly lit and its branching caves contain bandits, flesh-hungry cave fishers, and things even worse.[1]
