Ahsoka left the Jedi order, though she still carried her green lightsabers for a while. Eventually, she abandoned those lightsabers to symbolize her splitting off from the Jedi. Years later, Ahsoka faced down a Sith Inquisitor and defeated him using only her powers in the Force. When she took the Kyber crystal from his lightsaber, she purified it and infused it with her own energy. This resulted in the white-colored blade she is seen using through Star Wars Rebels.
