SU - Gem OC: Obsidian

So here's the gem who's shard is inside Dioptase's gem; Obsidian.

Basically they used to be one of the higher ranking officers in Yellow Diamond's faction, and extremely loyal to Homeworld & the Authority. Unfortunately, due to their dedication, some of the gems in Rose Quartz's rebellion felt they had to be...dealt with.

As in being assassinated.

So yeah, as a shard, the only thing really left of Obsidian's consciousness is her devotion to Homeworld & the Authority, which in turn influences Dioptase as I said in her bio.
