"She's off the Shits!"
Crack Diamond is a Diamond that has, quite frankly, lost her fucking mind. She is a crazed ruler who wants nothing more than to overthrow homeworld, the place she was discarded from.
Her powers include: Hypnosis, A Drug-Like Effect on her Fellow Gems, and the ability to contort as much as you'd expect some sort of professional preformed to accomplish.
Many of the gems in her court were not made by her own sweat, but were stolen from the various diamond's she has met.
Her base resides on Othaerus, a planet know for high and difficult rock terrain and formations.
