A gemwolf is a species I made up for one of my books. They are named after gems and have different powers. They have special amulets that are made of their namesake gem. If wearing the amulet, they become very powerful. However, these amulets have been hidden away from the packs, and they must join together to find them...or let the darkness take over their world. [Scroll Down] Aquamarine's brother is named Topaz. Specifically blue topaz. This is because aquamarine and blue topaz are difficult to tell apart if you don't know much about the different gem's qualities. But Aquamarine and Topaz have very different personalities. Topaz actually controls water. Anyway, I won't say any more. Sorry that I'm writing an entire essay!
