Seth

Seth is a young adult who really seems to like rocks and gems and all sorts of things. He doesn't really have many friends, everyone seems to shun him for being odd, but he doesn't really seem to mind. It means he can spend more time looking at things he is interested in, yayy.
He can name just about every single different type of gem and rock that he sees, and some he can even come up with a few interesting facts for as well.
