The living story
The story so far
It doesn't eat — not really. The Vent Mussel's gills are packed with chemosynthetic bacteria that drink the vent's poison and exhale food straight into its tissue. It sits in clusters on the chimney's flank, breathing poison and calling it farming, and it has never been hungry a day in its life.
Happening now
Its beds anchor the outer vent grounds, dark shells clustered like a audience. The shrimp swarm above; the Tubeworm's plume-city rises behind; the Mussel sits, breathes, and is fed.
What may come
Symbiosis is a negotiation, and the bacteria are winning — each generation, the Mussel relies on them a little more. One day it may forget how to eat entirely. The bacteria are in no hurry.

The Abyss
A desert with oases of fire. At the hydrothermal vents, farmers, armorers, and grazers divide chimney rights — and the Osedax sisterhood tends every fallen whale as sacred ground.
