The Montclaire family is one of the many known Shadowhunter clans.
Late in the 20th century, Céline Montclaire was a young Shadowhunter attending the Academy in Idris. Apparently due to her history of abuse with the Montclaires, Céline, in her desire to be loved, was easily convinced and manipulated by idealist Valentine Morgenstern into following him and the Circle.
