Port Town is a location in Final Fantasy Legend II.
The party comes across this town by the sea on their journey in search for MAGI. Rumors around this coastal town is that a sea monster, Neptune is apparently terrorizing this town. The bartender at the cafe mentions a cave that's so bright and luminous that the party will need the eye to see the truth.
The player can enter the sea by walking straight south from the town, and find the Undersea Volcano southwest from it.
