(Inspired by @-GreenCitrine- )
I was originally an Era 1 Mabe Pearl, from back before I became who I am today, I was rejected by the gem who was going to be rewarded with a Chabazite...but instead was disgusted by me. She perceived me as a "Defective" and she was right.
I carried a STRANGE black substance that only Chabazites had carried and used to create weapons of their own.
But the black substance was different for me, since it made me nearly corrupted everytime.
One day, when I was assigned to Pink Diamond, I met her Amethyst. And her Amethyst wasn't muscular and strong like all the other Amethysts, this Amethyst WAS tall, but she was....skinny! I fell for her straight away as she soon started to feel the same way later on. We secretly would always try to hang out when no one else was around.
Then the Gem War had came along, and I was forced to work with a Carnelian instead of the Amethyst I was in love with. Me and that Carnelian had fused, but we were unfused right away as Rose Quartz had shattered Pink Diamond, losing the link to our source of strength and invincibility....we had nearly escaped Earth, until the Song of The Diamonds had blown through Earths newborn atmosphere, making my Corruption even worse I was starting to corrupt again. and I was stuck like this for 3,000 years, until I finally reunited with Skinny Amethyst, and started a relationship with her.....
Then they fused, blah blah blah their gems melded together, blah blah....and now you know how I was back in the day...
