The White Rose led the rebellion against the Dominator and The Lady four centuries ago. Her power was a null field: an invisible sphere which surrounded her and negated all magic. She defeated her enemies but was unable to destroy them. She sealed the Dominator, the Lady, the Ten Who Were Taken, and many lesser demons in the Barrowland and placed protective spells and guardian spirits around them.
Centuries later a young girl demonstrated the same unique power to negate magic. She was considered the reincarnation of the White Rose and once again became the leader of the rebellion against The Lady and the Taken, eventually allying with her to face the greater menace of a newly awakened Dominator.
