Submariner — Sea Life

The Vitreous Siphon Oracle drifts around mineral vents like a living observatory, drinking trace metals through the crown of hollow tubes along its back. Its glass-dark shell pulses with amber organs that flare before pressure shifts, sonar ghosts, and hull stress events, which has convinced older crews that the beast sees a few seconds farther than anything else in the trench. It does not attack quickly. It studies, angles its beak toward the weakest seam of a vessel, and lets the sea finish the calculation. Salvaged Oracle tissue is prized by science crews because it continues to twitch in rhythm with nearby song-play energy long after the creature is gone. Properly contained, those organs can feed a steady trickle of AP through a voyage's instruments. Improperly contained, they whisper predictions into the comms until someone believes them.
