mothy's consistently used 四つの終末 for the series. This booklet is 四つの結末. Basically, it's a one kanji difference. That said, the meaning is exactly the same (the former means an "end; close" and the latter means an "end; conclusion").

I already made the suggestion in the discussion. We'll see where that goes. mothy's also referred to it as the "Four LastThings" series from Bosch's painting on his twitter recently (in reference to the last song, Master of the Heavenly Yard), so it sounds like a good time to consider retranslating the primary series title.

That would seem to be the case. Each Master has their own plan and Sickle sees that Hellish's plan seems to be the one that's going to happen (having a super weapon that destroys a forest that's 1/3rd of your country tips the scales pretty heavily).
