I'm confused by this whole bit:
The Starship Titan rolled slowly in the dark, dancing between the invisible jetsam, the ethereal flotsam, like some graceful leviathan swimming a terrestrial sea. All around it the other occupants of this region, the inspiration for the ship's lingering ballet, also pitched and spun in apparent counterpoint to the vessel's motion.
So why does it need to "roll slowly" because of the "other occupants"? To dodge them? Or is KJA just being meaninglessly poetic?
Titan's astronomers had dubbed the region Occultus Ora for some reason known only to them. The physicists called the things residing here exotic matter plasmids but, lately, those who'd been tasked with ferreting out their secrets had taken to referring to the strange objects simply as darklings.
Critical darklings, perhaps?
