Salt

  Salts do not have a history of subterfuge. They'd always given the impression of being 'sell-swords' with questionable loyalty at best. They may or may not deserve this reputation, but its safe to say they aren't the kind you send behind enemy lines.

  This was exactly the reason Homeworld did it. No one would suspect a Saltstone of being a spy. And, truly, no one did.

  They sent Salt to the Crystal Gems, injured and wide-eyed, to make the desertion seem real. Being a second-class citizen was too much, Salt claimed, and every gem there could relate. Kind Rose Quartz took the scuffed gem in and tended to her wounds. They promised Salt safety and Salt promised to help their cause. They lived in a warzone but the rebels found happiness with each other.

  The spy served Homeworld well. She gathered information; base locations, meeting times, strategies. Everything was leading up to a final raid that would wipe the Rebellion off the face of the colony. Homeworld would corner them against a cliff while they travelled. Homeworld would trap them and shatter them all. But Salt was having a change of heart.

  Homeworld never treated her with such kindness. Such genuine respect. She hated quartz soldiers at first, but Rose was different. Rose treated her like an equal. It was the system Salt had hated, but she'd been lead to believe it was just one other group. Salt had learned so much with the Crystal Gems. It was sappy, but it was true.

  It was a revelation that came to late. The raid happened and Homeworld shattered many of the rebels. It was only by the skin of her teeth that Salt managed to steer Rose and some other rebels away. Once she knew that they'd be away from the fighting, she went to try to save the survivors. To convert her Homeworld friends. Anything to help, anything to erase what she'd done.

  In the fight, a stray arrow poofed Saltstone. Her gem fell into the cracks of the rock face along the cliff; the space was too small to reform in. There her gem stayed for thousands of years. There it will stay until a certain gem-human hybrid finds her.

  Salts are known for being very blunt, no nonsense kinds of gems. They aren't stupid, but they aren't known for participating in the machinations of high society or manipulating others for larger purposes. They are straight forward and get the job done quickly. This gem is no different.

  Salt has a tendency towards cockiness due to her fighting prowess. She can act quite bitchy sometimes. She has a sassy, sarcastic sense of humor. She's salty about her gem having mid-low status. She is envious of quartz soldier because, although Salts just as capable as fighters, quartz are more highly regarded.

  Despite this, she does have a soft side. Buried deep, deep, deep down. Somewhere.
