Will Hastings is the youngest known member of a lineage whose members are frequently born with innate mystic potential. Although Will's mother Caprice nor his maternal grandmother, Professor Louise Hastings
, were born with such power, Will himself was, but not even Prof. Hastings, whose occult research was partially motivated by knowledge of her Family's history, was initially aware of it. Will was also born with a birthmark over his right eye, possibly a mark of his power. Presumably Will's father died or abandoned the family while Will was still quite young, since he uses his mother's original surname of "Hastings." As a child, Will, nicknamed "Jinx," developed close ties to Louise, although she was estranged from Caprice.
