The Warlock, the Witch, and the Empire

Jedi are being hunted across the galaxy after the Sith tricked them with the Clone Wars. Now the few remaining champions of the light are being pursued like animals of game by their own clone soldiers, as well as the ruthless Darth Vader.
But death isn't the only fate that befalls Jedi that are cornered by the Empire.
Some are captured alive and tortured to the point of embracing the dark side of the Force, becoming the emperor's new Inquisitors.
Such was the fate of (Y/n) (L/n), a Jedi that was captured early after the war's end and was put through the rest of the tests until his hatred against Darth Vader in a duel caught the attention of Sidious.
After a few trials and tests, the emperor made him his personal mystic, testing the dark side rituals he wanted to experiment on without fear of self-harm to his being.
Despite this prestigious position, (Y/n) hates the Empire and the Sith as a whole of what they have become and done to him, and secretly wishes for either the death of Palpatine and his champion or an opportunity to leave and create his own empire.
Such an opportunity for the latter may prove itself when he chases a Jedi to the Unknown Regions of the Galaxy and discovers on a primitive planet a Witch that wishes something similar to him.
