Exy
"Exy",
some nickname from a forgotten past. They call him a Storm
Chaser because he's got a death wish: treasure hunter, pirate, lunatic.
That pendant belongs to something bigger, and trying to find
out what
has already driven him mad. He's a gentleman, though, and he's glad to
help out who he can along the way. Try to touch the gem, though...
well. There aren't any left alive to tell what happens after.
Check out Exy's "companion", Tecate,
as well.
