The following account was recorded in the agent's log during your transmission: Towering obsidian pillars are sprouting from the seafloor in a hydrothermal vent system, their facets reflecting the faint glow of bioluminescent organisms like a thousand tiny mirrors. Uh, the air's thick with the scent of hydrogen sulfide and it's eerily still – not a single sound, like the whole world's holding its breath – except for this low, almost imperceptible thrumming noise, like some sort of impossible, underwater echo of the Voyager Golden Record. Snowflakes are collecting on the surface of superheated water jets, somehow not melting. The water's charged with an electric current that's making the vent organisms pulse in sync.
