Though Cassandra Webb suffered from a lifetime of blindness and many years of neurological deterioration, she compensated with her profound psychic abilities, establishing herself as a medium. Her considerable talents brought her to the attention of the United States government. Initially recruited into S.H.I.E.L.D. prior to the explosion of mutants across the world, Webb was a considerable find. In her early days with S.H.I.E.L.D., she was used as a code breaker and interrogator. She was one of the best. With the recent changes in S.H.I.E.L.D. and the ascension of mutants, bringing in more telepaths, Webb's role has changed, but she is no less important. Webb now works as a link between many of the young telepaths being used to monitor S.H.I.E.L.D. agents across the world. She also soothes some of those agents who may have undergone some mind-tampering in their past. Her most frequent customer is S.H.I.E.L.D. Special Agent Wolverine.
