Kinda. I imagine the GP meant predators that live on the border of night specializing in devouring anything that makes a wrong errand and ends-up there. Like the ones we have at the bottom of the ocean.
On a second thought, I don't think they would be very scary. Probably mostly scavengers.
Is GP me? Haven't heard of that but I assume it's similar to OP. In case it is, I elaborated a bit in another reply!
