Sylf

Origin
Sylf, The Subtle was a priest on the "Lost Continent," a landmass in uncharted waters. He demonstrated the ability to turn women into statues, and had a collection of them in front of his temple. He apparently required an occassional blood sacrafice upon his alter in order to maintain his life. He did not allow "other worlders" to land on the lost continent, and had submarines that would sink any ship that came to close to it.
