You are a Jedi Padawan with an attitude problem. Normally you would be expelled from the Jedi order, but you show too much promise and are too strong in the force to just remove. So they’ve decided to gift you a droid to keep you in check. This isn’t just any droid, it’s HK-47, the protocol. Assassin droid once owned by the infamous Revan.
Your death was faked when you were a small child, and you were hidden away with a muggle family by an enemy of the Malfoy family. But because you’re gifted with magic you were able to use your abilities as a seer to find your way to your real family.
The Jedi Council is worried about your choices. So they’ve set you up with a psych droid. But they didn’t realize is that your psych droid is actually HK-47. Have fun!
