Elaboration on ending options that need elaboratin'
Elaboration on if magic were to be killed in its human body along w. hugh of course bc hugh kinda dies in every ending lol:
Having finally achieved humanity (its possible end goal), Magic is now susceptible to many human ailments. Including death. So somebody takes him out. Note that this would take something so powerful that this is an EXTREMELY unlikely outcome, i.e. an extreme homebrew spell(*/**) or something analogous to the Lance of Longinus/Olivia perpetually riding Hideaki Anno's cock.
Anyway. Since it's like permanently ingrained in a large portion of humanity's genetic makeup (not to mention the universe itself), everything would go kaput, in a similar manner as what would happen if Hugh wound up eliminating the force himself before it takes hold of his body. This route could also be seen as a much more traditional approach to the TANG/Anno ending.
* When I say "homebrew" I mean that all spells were discovered/created by SOMEBODY. Think about the half blood prince on a crazy OP metaphysical level.
** Or, you know, maybe Legilimency.
