Lord Fanny is a transexual woman and a member of The Invisibles. Born Hilde Morales in 1972, Lord Fanny was raised as a girl by her grandmother, a notoriously fearsome witch, as men in their culture could not become witches. Before joining the Invisibles, Fanny was initiated into magic.
She survives the series, though in one glimpse of the future, Fanny is depicted as having become obese.
