Colonel Senks was a male Human operative working for Darth Baras. He acted as a leader within the Corellian resistance throughout the Battle of Corellia, which was a key engagement in the wider Galactic War.
During the Battle of Corellia, Senks, while secretly employed by the Sith Lord Darth Baras, masqueraded as a leader among the Corellian resistance fighters, protecting Baras' classified information. He operated from a fortified location within the Labor Valley region of Coronet City, equipped with a network of hidden tunnels for swift escapes. Darth Vowrawn devised a plan to eliminate him, providing the Emperor's Wrath with pulse disruptors to seal off Senks' secret routes, effectively trapping him. When confronted by the Sith, Senks confessed to his role as Baras' informant. Mistaking the Wrath for a renegade Sith he was tasked with monitoring, Senks begged for his life, revealing his manipulation of resistance forces in battle and arguing that his absence would lead to their defeat and a loss of imperial advantage. Disregarding his desperate appeals, the Wrath executed Senks and destroyed his data repository.
