Ashley is yin to Will's yang in the Sanctuary's dual agenda of "preserve and protect." Arrestingly beautiful, she is tough as nails, physically adept and a skilled fighter making her perfectly suited to her calling as monster-hunter supreme. Ashley has moments of vulnerability but it's a side she deftly covers with a veneer of bravado and fearlessness.

Growing up in the world of the Sanctuary with her mother, Dr. Helen Magnus, she has come to accept the impossible as a matter of course. And while there are the usual generational sparks between mother and daughter, Ashley is acutely respectful of her mother's work and knowledge.
