I am too skilled to be even realized as a Sith. No matter, a bit of Force Lightning should help.
—Sophia McLaren
Sophia McLaren was a skilled Sith Knight that lead the McLaren Confederacy of Independent Systems. Excellent in her Force powers, trained as a three year old, Sophia was not a person to be reckoned with. Many fell to Sophia's power, and her daring was unquestionable.
She often had some disadvantages, such as a genetic disorder and mental retardation. This is why she often cries when realized that she was not the most powerful. Due to this, Victoria Price and others often were forced to say "You are the most powerful, Sophia, and never forget that".
Eventually, Cynthia, one of her apprentices, killed her in a lightsaber duel, because Sophia was causing some bad things to happen. She was to remembered for a long time.
