Until we get more info, this is my official prediction:*The question of “Why does one species get to control The Sun and Moon?” gradually drove a wedge between the different species, which fits the theme of “paranoia and mistrust”.*This eventually led to conflict, which ended the golden age of harmony.*It would be easy enough to spin these events into a cautionary tale about not trusting other species. This is why Twilight’s message is something modern Equestria needs to be persuaded on.
