Rajan Callon was a new addition to the Sith Brotherhood, roughly three months after Darth Nemesis found and recruited Saias Kargon and Xahruk. His talents with the lightsaber, as well as his extensive knowledge of Ataru, granted him favor amongst the Hands of Darkness as a fine warrior. Rajan also demonstrated proficient abilities to lead, often making him the prime candidate for more delicate missions which require leadership beyond that of the Shadow Imperium's standard generals.
