It’s all that’s on Hal’s mind: pressure.
Millions of tonnes of water overhead constantly press down on the submersible. It’s built to an existing specification; a design iterated upon and propagated across human space decades before. What they call a standard template machine. Proven.
The raw materials that compose it were scraped together by the involuntary colonists from the scraps of the wreck and what few minerals their other haphazard equipment has been able to liberate from beneath the ice. But the fabricators took in what the colonists had, and what they output fell within all the standard minimum safety parameters for the planned depth.
The submersible’s cabin groans, terribly slow and even, as the beast’s tentacle tightens its grip. Someone whimpers. No one else hushes them, even as they all hold their breath.
Hal wishes the submersible had met more of the standard safety parameters. Although nothing is designed for this. Although none of the colonists now trapped with him in this tiny reinforced bubble of metal and glass expected to find something like this down here. Or, more exactly, to be found by it.
The tentacle – or perhaps the arm, if this creature has more in common with terrestrial cephalopods than superficial appearances – shifts again. Hal watches in appalled silence as hundreds of suckers pucker and undulate, rippling across the glass bubble of the submersible’s cockpit. In the gaps between its labyrinthine flesh there is only darkness.
They are going to die down here.
