From CoH Comic Index
Aurora Borealis is an in-game character in Paragon City and a member of the Vindicators supergroup.
For a brief period, she gave up her body so that Sister Psyche could survive and continue to fight during the First Rikti Invasion. The merger, however, had some serious consequences for the more experienced telepath.
Aurora was first seen in flashback in Issue #1 of the Top Cow Comics incarnation of "City of Heroes" as an echo in Sister Psyche's head. She would later be seen in physical form alongside her fellow Vindicators in Issue #17.
In the Praetorian Universe, Shalice Tilman never gave up Aurora's body and continues to use it today as Mother Mayhem.
