Heroes are a lonely lot. Whether a Superhero, psychic, the Last of His Kind, or an Ignored Expert fighting uphill for the sake of the ungrateful masses, heroing is a solitary and unpopular path that separates one from all other Muggles and even loved ones. His own family can come to reject the hero, denying their approval or outright scorning him as a freak, it's not like their career choice is following the ancient family legacy. Or is it? Compare Rags to Royalty, when the legacy is monarchy. May be passed on as an Unexpected Inheritance.
