The Veil (Nar Shaddaa)
During the era of the Galactic War, approximately around 3640 BBY, a trio known as The Veil functioned on Nar Shaddaa. This group consisted of three male Human Cyborgs: specifically, Veil One, Veil Two, and Veil Three. The Veil seized authority over the manufacturing of the CN-12 sensor chip, wresting it away from the Cult of the Screaming Blade. Later, Kallig, a Sith Lord and the owner of the Cult, contacted the Veil seeking the CN-12. The Veil proposed a trade: the chip in return for assuming command of the Cult.
