Pleasures of the Harbor

From the introduction:

Pleasures of the Harbour is a mystery adventure in the style of the film Magic Blade and the book Horizon Bright Moon Sabre, and is meant for a party of any level. In a boat city named Ao Town on the southeast coast of China, the players find themselves swept into a web of intrigue and danger.

Although this adventure is intended for characters of any level, low-level characters will need to use their wits and form alliances with NPCs in order to survive. High level characters may face higher level threats, as NPCs should respond to their presence by seeking powerful allies.
