Tunnels of the Ningyo

The Tunnels of the Ningyo were a cluster of strange caves and circular tunnels beneath Kaigen’s Island. Mostly they proved dangerous for explorers on the island, due to pitfalls, collapsing roofs and toxic air. Most troublesome was some evidence of the taint, believed to be remnants of the Dark Wave.

One such tunnel was discovered by Yoritomo Ryoma who was overseeing construction of a break wall for Broken Wave City. With the aid of Moshi Kameko he explored the tunnel, finding many gold coins.
