Now that the pattern has become apparent, I find myself looking forward to each week more and more. The fairies are taking aspects of human history and culture and experiencing it from inception to eventual decline and ultimate collapse in the course of a few hours or at best days. First (or last given the airing order) the fairies try their hand at industrialization, then serialized entertainment, then civilization, organized religion... and if Grandfather's words are to be believed, this sort of thing is happening
a lot.
In a weird way, in-universe, humanity is seeing its own life flashing before its eyes. More specifically, it is watching a low-budget, heavily-condensed, blisteringly satirical clip show of its life flashing before its eyes. And the entire cast of this clip show is made up of hedonistic perma-grinning borderline sociopaths.
