I have a somewhat confusing question about Heroic Spirits. Do they exist outside of the regular parallel worlds? I'm wondering this due the fact that the Fate/Extra series has had appearances from servants from stay night, Zero, and Apocrypha in that game (with none of the them having separate pages such as in Lancer (Cú Chulainn) or Lancer of Red's case) and the fact that Gilgamesh has separate pages for his appearances in different works in which most use his stay night appearance where he retains his Archer-class (with the exception of Prototype or appearing as a different class such as in Grand Order or Fate/Extra). This also the case with material books as well, such in the Fate/Apocrypha book, in Joan of Arc' section, Gilles de Rais (Caster version) is listed as her natural enemy, and while he does appear in Apocrypha he resembles his Saber version more than his Caster version.
