Gem Skeleton

The Gem Skeleton is a mysterious entity that takes innocent gems and stores them away. It was originally a joke set up by Colin, but months after the joke, the identity came back and surfaced on the news.

Powers
The Gem Skeleton was shown to have experience with using Dark Aether, an advanced sub-element that was never seen before. He also has shown mastery with a dual saber, surpassing the likes of Colin and Dayton's weapon masteries. Nobody can tell if he had years of training, or if he is just gifted because he is a very unpredictable fighter.

His style of fighting usually differenciates between the Panthera style and the Corax style, making him slow and defensive sometimes, but swift and aggressive other times.

Identity
Only he and Vitae know about his secret identity, due to being converted from good to evil by her. That is why he is not obedient to her at all and does not care about her needs.

Motive
He is indeed evil, but not on anybody's team.
