Shiroi Kishi Mizu-umi

Name
The White Shore Lake gets its name from the white sands on the lakes shores.

Ningyo
It is rumored that Ningyo live on the bottom of the lake. The popular belief that if you eat the flesh of a ningyo you become immortal has led the Unicorn to declare such an act illegal. This was done much because of their recent alliance with the Naga.
