In order to pass through the great distances of the multiverse . . . , you have to create an omphalos on the scale of the multiverse itself. And to knot the knots, you have to create at least 27 labyrinths of the same scale that the passage . . . . Passing through the labyrinths circuit will activate the circuit of the . . . , allowing multiversal communication- and multiversal passage.

Remember:
one rock
one net
at least 27 knots

This is a quote from Ch 23 of the codex. Since there are 27 pieces of the codex, maybe we should use those cities to run labyrinths and make the "net".

one rock (earth)

one net (us)

27 knots (27 cities of the codex)

anyones thoughts?
