After escaping from the Defenders of Man, Agent Nova Terra met with Emperor Valerian Mengsk, who promised her the Griffin and his Covert Ops Crew in return for her loyalty. She accepted, and after recovering some of her memories set out for Tarsonis.
The Griffin deployed her and her crew outside of a Defenders of Man base, allowing them to garrison structures surrounding the base while Nova Terra infiltrated the facility.
After discovering the Defenders of Man's plans to stage a feral zerg attack on Tyrador IX, Nova took the Griffin through the zerg forces in orbit and established a base near their hatcheries. After fighting the zerg and Tal'darim, Nova and her Covert Ops Crew escaped the planet. However, the Griffin was boarded by HighlordAlarak of the Tal'darim. Alarak made a bargain with Nova, and lead her and the Griffin to the planet of Jarban Minor. There Nova was to gather terrazine to undo her mind wipe.
With her memories slowly becoming restored, Nova took the Griffin to location of the last mission she remembered doing for the Defenders of Man; the city of New Andasar on Antiga Prime. Nova took the Griffin to the surface, and dropped forces to establish a forward base. After she recovered her memories and discovered the leader of the Defenders of Man, General Carolina Davis, Nova left Antiga, and contacted Emperor Valerian Mengsk aboard the Griffin.
