* WhatCouldHaveBeen: At some point, an official artwork showed Halo in a [[Franchise/StarWars Leia]]-like slave girl outfit, for the never released Book 4. Because of a dispute with the publishing house at the time, Creator/AlanMoore and Ian Gibson bailed out of producing any further work for the series. Originally the series was to span Halo's entire life into her old age, but because of creative disputes we got only what exists now. Moore apparently had the whole thing plotted out, but to this day, only Creator/NeilGaiman has ever been allowed to know the whole story.
