st. killgars school of misfortunate children

Long ago, over 500 years ago, a man named Mr. Fitzrosé founded the St. Killgars institution for Misfortunate Children; the very same man still operates the institution now. Mr. Fitzrosé is roughly sixty hundred years old; legend has it that the school was passed down through the Fitzrosé family bloodline... This school is administered by an extremely wealthy guy, yet only impoverished, neglected, or orphaned children attend; is this due to their bad reputation, or was it done on for a reason?
