The legend of Lord Nyax was a part of the mythology of Corellia. A scary bedtime story was told to Corellian children that Lord Nyax came to steal young boys and girls from their beds. Shortly after the Clone Wars, the Lord Nyax story became associated with Darth Vader, who also appeared, seemingly at random, to steal and kill Force Sensitive children in the dead of night before they could grow to become Jedi and a threat to the New Order.
