INTERLUDE TWO
Overview
This interlude recounts Shroud’s evolutionary history: a dense, energy-rich but lightless atmosphere enabled life to move from sea to air, build floating biomes, and store oxygen safely in tissues. Deprived of vision, organisms perfected hearing, culminating in echolocation, which underpins the planet’s giant, complex terrestrial ecologies.
Summary
The narrator explains how, on Shroud, a dense atmosphere created a gradual transition from sea to air, enabling life to leave the ocean. Energy-rich gases and atmospheric chemistry offered immense metabolic wealth, driving the evolution of walkers and vast sessile structures that channeled and harvested the air.
Life engineered floating and flexible terrains that rode the swells, spreading via the Everstorm’s winds. Oxygen remained locked in tissues rather than free in the air, avoiding its corrosive dangers and storing energy safely for later use.
Because the thick atmosphere blocked sunlight, vision and bioluminescence never evolved. As mobility increased in air, organisms needed better sensing; hearing arose first, exploiting the dense medium and sparking an arms race of stealth and auditory acuity alongside escalating body sizes supported by advanced exoskeletons.
The chapter culminates with a key leap: some creatures learned to detect their own echoes, transforming hearing into active sensing. Echolocation became a decisive adaptation for navigating the permanent darkness and for predation and survival among increasingly massive, complex life forms.
