From CoH Comic Index
When she was a child, Ashely's parents (who were possibly members of the Midnight Squad) showed her a Dark Void Beast, which they kept in their basement. Scared out of her wits, she saw this creature as a sign of things greater than the world she knew, and it encouraged her to learn more.
Ashley joined the Midnight Squad on the same day as the 2002 Rikti Invasion. She had to watch as her fellow Midnighters were killed by the Rikti and believed that their quick deaths and the Rikti's vulerability to magic were connected.
She has since hung around the campus at Cap au Diable University, trying to find the connection between the various origins of power.
