Asajj studied under Dooku during the Clone Wars.Â Although she was only a Sith apprentice, her powers quickly drew a lot of attention.Â A lot of which came from Palpatine who ordered Dooku to destroy his apprentice (which he failed to do).Â Asajj struck back at Dooku with two Nightsisters, but was unsuccessful in her assassination plot.Â Asajj wiped the floor with Anakin Skywalker and Obi-Wan on more than one occasion. Before Palpatine thought she posed a threat to him, he was impressed with her lightsaber skills.
“The child’s skills with a lightsaber are most impressive. You have found a promising disciple, my apprentice. She shall serve us well.”
