Karre

Karre was a Force-sensitive human male raised by the Galactic Empire with his twin sister, Am. Karre and Am were created using the dark side of the Force and raised to destroy the New Republic. Karre wielded a multihued lightsaber as his weapon. Wanting to save his sister from death after the activation of their Gemini-class Star Destroyer, Karre stole its kyber crystal and escaped from his sibling. He then arrived on a planet and promised to bring his sister with him.
