Set in the alternate Sombra timeline during The Cutie Re-Mark.
Sombra found the young unicorn shortly after his banishment ended. He saw in her a shred of potential. He could have dominated her will...but perhaps she'll be more useful like this.
And besides, it had been quite a long time since he'd taken an apprentice.
An entry in Imposing Sovereigns IV, using the prompt King Sombra/Strength. Good luck to the other contestants!
