Something bashed against the submarine with such a tremendous force that the vessel rocked violently from side to side, throwing people back and forth. Jacob and Whistler weren't ready for the first of these, and they earned bruises as their medals, but the second time the creature shook the ship, they clung to pipes that rattled in their holdings, as if they themselves feared the larger beast that came to feast upon them all.

The sweat rolled down Jacob’s forehead. It made an ocean on his palms. The chronometer showed just five and a half minutes remaining. Time was the greatest pressure beneath the sea.

And it was to the bottom that the vessel now plunged, into the waters that were blacker than any black on land, into a gloom that was more consuming than the deepest night. Were the crew not focused on their frenzied work to stop the steep descent, they might've glanced out one of the many round windows, and they might've thought that they were looking into the black iris of an evil creature—and they might've been right.

In the black abyss, there were creatures that even demons feared. No one knew what they looked like, not even themselves, for they were blind, and though many were scavengers, seizing and consuming any stray bits of food that'd sunk down from the higher levels, there were predators too, just waiting for larger prey.

The abyss was awake, and its entire population was stirring, some to flee, some to investigate, but many, all too many, to feed. Fishes with fangs came. Bulbous bloated creatures came. Shelled monsters with massive jaws came. Things that defied description came. Every form or shape that stalked the nightmares of a child lurked there in the deep, and they all descended on the Lifemaker, no eyes to see, but many mouths to taste.

They dived into the ocean of shadow and smog, adding to it with the fumes of their own aircraft. The goggles were useless now, but Jacob kept them on, in case there might be some break in the murky pool. It was fitting that the Worldwaker had passed through there, with the shark emblem painted on brightly. In those deep waters it could not be seen. It almost felt like it had lured them in. The dolphins do not hunt the sharks.
