Real name Gudrun Dunst. She's a descendant of a proud Pureblood family, traditionally associated with the Humanists. The old photo we have obtained shows her at age 19, when she was admitted into one of the secret Humanist research facilities. Coming from the field of biology, she became involved in Humanist experiments on maximizing the magical potential of Purebloods. She left the facility several years ago due to apparent disagreement with Humanist leadership over ideological matters.
Even before that happened, she has fallen into disfavor due to her 'immoral' experiments she refused to abstain from.
