Thorus, a male of the Human species, held the rank of Sith-Imperial officer within the Sith Empire and his service took place during the period known as the Cold War.
Throughout the Cold War, Thorus orchestrated the deaths of numerous non-combatants, numbering in the hundreds, and initiated widespread bombing campaigns targeting defenseless communities. These actions were a direct violation of the orders issued by Imperial High Command. Though he felt remorse for what he had done, Thorus remained in the service of the Empire.
In the year 3643 BBY, Colonel Thorus, an Imperial officer with whom Elara had prior acquaintance, encountered the commanding officer of Havoc Squad. After Thorus provided Havoc with the necessary intelligence, Elara suggested that he be executed to prevent further acts of brutality. Nevertheless, the lieutenant chose to release Thorus. Thorus was grateful for this act of mercy and it is possible he abandoned the Empire due to the weight of his past actions.
