Cassidy( age 14) is from a warrior village that can copy all of the strengths and powers of whatever monster they kill by using part of their living essence to trap in their gem. They can only copy one monster at a time and can only do it some many times in a life time before it would kill them if they tried. Extreme damage to the gem can hurt the owner and in certain situations destroying it will kill them.
