oh boy, is this a reference to ouroboros with the eternal cycle of destruction and rebirth?
I wonder how they will go back to the river, the chapter makes seem as if they ended up on the moon looking back at earth.
Maybe they need to be out of the loop to reach the estuary.
So to me now, the Great River, along with the cohort and the absurd number of contestants in this Nightmare and also all the other creatures in it - seem altogether like a much larger and unimaginably more violent version of the Dr. Who 'Gridlock'-episode! (S3 E3) đ
