DESCRIPTION
We’ve found a new planet, home to octillions of the most extreme beings living in the most absurd and deadly hellscape. In absolute darkness, crushed by the weight of mountains, starved of oxygen, cooked alive, bathed in acid, salt, or radiation, they live for thousands, perhaps millions of years! It turns out, this planet is not in space – it is inside the crust of Earth!
This is the deep biosphere.
