Thalassos - The Abyssal Depths
A world where the deepest ocean trenches hold the greatest civilizations
World Overview
Environment: Entirely underwater planet with crushing depths and bioluminescent life
Core Theme: Pressure creates strength - the deeper you go, the more powerful you become
Climate: Crushing pressure zones, thermal vents, abyssal currents
Atmosphere: No surface atmosphere - all life exists in water columns
Gravity: Standard, but pressure increases exponentially with depth
The Fundamental Reality: On Thalassos, society is literally stratified by depth. The surface waters are considered the "shallows" - home to the weak and outcast. True power and civilization exist in the crushing depths where only the adapted can survive. The phrase "going deeper" means gaining status, power, and respect.

The Fundamental Reality
The Hidden Cosmic Truth: The Gravity Well Leviathan
The Crashed Cosmic Entity: Thalassos's extreme depth-based civilization exists because a cosmic entity made of pure gravitational force crash-landed in the planet's ocean depths eons ago. This living gravitational consciousness - essentially a cosmic black hole entity - became trapped at the bottom of the deepest oceanic trenches.
The Gravitational Prison: The entity is too massive and gravitationally bound to ever escape the ocean depths, creating all the crushing pressure zones that define Thalassos society. The deeper you go, the closer you get to this cosmic gravity consciousness, which explains why pressure increases exponentially and reality begins to bend at the deepest levels.
The Depth Hierarchy Origin: The entire social structure based on survivable depth exists because inhabitants unknowingly organize themselves by proximity to cosmic gravitational power. Those who can survive deepest have learned to work with rather than against cosmic-scale gravitational forces.
The Leviathan Manifestations: The massive sea creatures dwelling in the deepest trenches aren't just large animals - they're manifestations of the gravity entity's consciousness. The "leviathans" are extensions of the cosmic gravitational being, which is why Leviathan Speakers can communicate with them.
The Deep Truth: The inhabitants don't realize their entire civilization is built around a cosmic gravitational consciousness that's been trapped in their ocean depths for millions of years. Their depth-based society, pressure mastery, and reality-bending abilities at extreme depths all stem from learning to coexist with a living cosmic force of gravity.
