Everything Under the Moon

This is on a necklace I've had since I was in middle school. No idea where I got it, but I wore it a lot before I got self conscious about wearing "weird things" or just got tired of the hassle of necklaces and forgot it existed.

Medusa.

I'm not yet familiar with the lore on medusa, but I know this film is about one of plutonian aspects:

Thanks guys! I'll have to look into this a bit more. Can't for the life of me think of how I would have come across a Medusa in my middle school years!
