Nova returned to the Dominion after escaping from an enemy facility. Unable to recall her recent memories, she learned that she had seen working for a secretive opposition faction- the Defenders of Man, and was now wanted for treason. Emperor Valerian gave her a chance to prove her loyalty by leaning a covert operations team against the Defenders. Aided by Reigel, the emperor's weapons and technology specialist, she recovered a memory that led her to infested world of Tarsonis.
