Will be interesting to see how Sel handles the pacing from this point on, will be huge whiplash to return to the sandbox/chapter 4 and before normal at any point after this update. While the game still has 5(?) years left until completion per his own timeline, things seem to be reaching a boiling point that would require a somehow bigger revelation than the things spoken plainly in this update to bring that boiling point back down to a sizzle; if in the next 5 years the story returns to the old pacing, it will either be well done because of something currently not present in narrative, or it will be simply bad.
While a lot that was revealed was both foreshadowed and theorized in some form by the community, and reading the recent story with that in mind didn't detract too much from it, by stating it outright in the text itself to not only the characters but any and all readers, Sel has sort of locked himself into future text reflecting the revelations, lest readers lose interest from the whiplash. Treading water with some character arcs for the sake of others, or some characters not having events/focus for months to years irl isn't gonna work after this update, and it barely did before.
