I'm referring to page 15, book one. Parson, prior to being summoned in to Erfworld, is talking about the “marbits” in Lucky Charms. He then goes on about “quantum staleness” and a computer that doesn't use “bits, or qbits” but marbits.

When I first began reading, I thought that maybe Charlie was a supercomputer comprised of marbits in a hive-mind or something. Maybe Thinkamancy, or maybe pulling toggles or pressing buttons. Who knows? Maybe Marbits take pleasure in that sort of thing.

I've skipped through much of books 2 and 1 and the prequel, but I've not seen anything which seems like it would be a marbit computer.
Granted that nothing about arcane knowledge was a requisite for Parson being summoned to Erfworld, so there's no reason for his quip about a marbit computer to have any bearing on anything in Erfworld, but … does anyone else think that maybe it will appear somewhere, if it hasn't already?

Either it's exactly what it seems, just referring to the fact that marshmallows are in a superposition of stale and chewy until observed...

Or perhaps Erfworld itself is a simulation running on a Marbit-based computer.

Ooooh but maybe there's a larger theory that the whole simulation is in fact Parson's coma dream having choked on a stale marbit...
