[@Akayaofthemoon] Yeah, I definitely think Bloodstone should be pretty flippin' powerful if it is all of us against him. And I like the idea for Aquamarine.

As for Evenkite, I'm going to have to think a bit. It's not really used that much and doesn't have any lore behind it as it was only discovered about 60 years ago, not to mention it's quite rare and isn't really used much outside of geological studies. Almost everything about her as a gemstone was based either off the stone's physical properties with a few references to the region in which it was found. :P
