Abiotic Systems

This hub tracks the environmental mechanics that dominate Tethys settings. The focus is physical forcing: chemistry, circulation, and hazard geometry that determine what can move, settle, or survive.

Geochemical Engine

11 min

Volcanic degassing, sulfur turnover, and basin stratification create the base energy gradient that controls exposure windows, transport, and survivability.

Key Forces

Volcanic sulfur flux · Photic zone euxinia pulses · Chemotrophic-primary productivity

Hazards

Sulfide breakthrough · Acidic vent plumes · Anoxic basin overturn

Book Relevance

Determines crossing windows, safe anchorage cycles, and collapse points in Book One settings.

Climate and Circulation

8 min

A greenhouse coastal world with high sea level and unstable circulation cells makes weather routing and thermal gradients primary constraints on movement.

Key Forces

Super-greenhouse heat load · Tidal bottleneck amplification · Coastal monsoon shifts

Hazards

Hyper-storm corridor lock · Heat + humidity fatigue · Visibility collapse in vapor fronts

Book Relevance

Frames pacing for supply runs, maritime timing, and settlement resilience.

Tectonic and Hazard Architecture

9 min

Arc fragmentation and shelf break geometry define where routes exist at all, while ashfall, collapse, and surge create periodic network failure.

Key Forces

Intra-oceanic arc uplift · Shelf-edge collapse corridors · Ashfall shelf deposition

Hazards

Pyroclastic surge fallback · Slope failure · Route severance after eruption cycles

Book Relevance

Explains strategic choke points and why frontier logistics dominate setting behavior.
