Before we start

You are a gem, Emerald specificly, who has been sent to earth to replace the rouge peridot who failed the cluster mission. You are a smart, middle class gem, you have a wepon, you're creative and funny. But no one knows this, and no one on home world seems to care. Until, you land on Earth, and meet Steven Quartz Universe, and his big group of gem friends. (NO LEMONS!! You're 13 he's 14)
