Credence

In his youth, Credence was adopted by the leader of a No-Maj anti-witchcraft group called the New Salem Philanthropic Society, Mary Lou Barebone, who was dedicated to eradicating magic. Credence was subsequently forced to repress his own powers under the watchful eye of his adoptive mother, developing a dark parasitic force, known as an Obscurus. Credence's situation made him an attractive weapon to dark wizard, Grindelwald, and after the death of Mary Lou, Credence would soon learn a lot more about himself and his true family.
