Aurora Borealis is one of the signature heroes of City of Heroes.
Aurora had a very unique introduction to the "big time" of the hero world. When Sister Psyche burned out during the Rikti War, Aurora was the one her comatose mind choose to 'mind-ride'. for the next three years both women shared the same body, and generally went by the name of Sister Psyche. In the end it was her husband, Calvin Scott, who had enough of it. Though not an experienced contact, he was able to direct heroes though task forces that eventually led to Psyche being freed back into her own body, although her mental control of Malaise was lost in the process. Aurora then took on his role as Psyche's sidekick, although it's amazing the two of them can still stand each other after so long of forced cohabitation.
Aurora is the trainer for Independence Port, near the hospital where Sister Psyche once rested.
