When her family was violently betrayed and her telekinetic powers became destructively apparent, Nova was forced into hiding in the crime-ridden slums of Tarsonis' Gutter. The story of Nova's emergence from the Gutter is apocryphal, but the burden of psionic abilities and the pain of her family's ruin led her to seek refuge among the very Ghosts her parents hoped to keep her from.
Supremely dedicated, Nova excelled as a trainee in the Ghost Academy on Ursa, eventually earning the questionable reward of a mind-wipe that erased all recollection of her tragic youth – and the majority of her long-term memory with it.
As a full-fledged Ghost operative, Nova's duties have included battling zerg, investigating the psionic killers known as Spectres, and even dealing with noted enemy of the people Jim Raynor. Her service record has seen her assigned tasks of increasing importance to the leadership of the Dominion, and she stands ready to be dispatched on missions that will make her past pale in comparison.
