Fishing Villages
Capturable settlements that boost the gathering of nearby sea resources and act as an infinite source of fish. The surrounding cliffs block access except from the sea, and the inhabitants first need to be rescued from Bandit Catamarans and predatory Sharks. Unique mercenary ships could also be enabled by controlling them (Similar to Shaolin enabling Wokou Junks). Fishing villages could appear on other maps such as Pearl Delta, Moluccas, or Maracaibo.
The appearance of the villages should be based off the stilt houses and houseboats of the Sea Nomads.
These villages would fit perfectly with the landscape of rocky shores with little room to build.
