AlsoSEALED MOVE · DAY 76 · 10:42; the buff envelope
A buff envelope pinned to the box world's noticeboard: an adjourned game nobody resumed, beside the one he resigned; its date is the last stroke of Episode 1's painting clock.
In chess an adjourned game waits on a sealed move: the next move written down and locked in an envelope until play resumes. This one is pinned in the box world's foyer beside Board 14, dated with Episode 1's painting clock, and nobody ever opens it.
