GR translation: pacts sworn to in rooms...

[Mike Jing]

P190.23-31   So it is here, grouped on the beach with strangers, that
voices begin to take on a touch of metal, each word a hard-edged clap,
and the light, though as bright as before, is less able to illuminate
. . . it’s a Puritan reflex of seeking other orders
behind the visible, also known as paranoia, filtering in. Pale lines
of force whir in the sea air . . . pacts sworn to in rooms since
shelled back to their plan views, not quite by accident of war,
suggest themselves. Oh, that was no “found” crab, Ace—no random
octopus or girl, uh-uh. Structure and detail come later, but the
conniving around him now he feels instantly, in his heart.

"pacts sworn to in rooms since shelled back to their plan views, not
quite by accident of war, suggest themselves."

What is this about?
