Beneath every road lies another world, and beneath that, something still awake.
TDThe Deepways
Overview
The Deepways are a continental underground network stretching beneath lands and seas, a world of humid tunnels, immense crystalline chambers, and geothermal lakes. Its routes connect settlements separated by hundreds of miles, though cave-ins and flooded passages constantly redraw the map. Rootcore crystals and other Origin-linked resources make the region coveted, while reclusive peoples and ancient mechanisms resist easy conquest. Travelers find no true horizon here, only layers of darkness, reflected light, and rumors of a buried machine-god.
Cultures
Zuciver enclaves preserve quiet, oath-bound customs shaped by long isolation.
Qhacret communities treat craft, memory, and guardianship as parts of one sacred duty.
The Whispering Woe Naga maintain older, secretive traditions around deep waters.
Surface-born delvers have adapted homeland customs to life without sky or seasons.

4 settlements

Medium · Port settlementEast QuayLake port and ferry junctionThe name came from a founders' homeland and now describes a busy landing on an underground lake.
Vast chamber complex · Ancient ruinThir'NoshSacred machine site and expedition destinationThe Qhacret regard its ancient machine womb as the birthplace of the first Mage-Forged Guardian.
Small · Farming enclaveLong MeadowFungal cultivation and caravan refugeA borrowed homeland name persists despite the settlement being built across a broad shelf of damp stone.
How they spread
PatternSettlements cluster around dependable water, food-growing caverns, and safe junctions, with long uninhabited stretches between them. Communities along major routes often combine trade, repair, and refuge functions.
The High Orchard route crosses the upper humid galleries.
The East Quay passage links surface shafts to the central lakes.
The Lower Run carries crystal and metal between deep settlements.

The land
Climate and ground
ClimateA patchwork of warm, wet chambers, cold drafts, and volcanic heat, with no ordinary day or night.
TerrainA continental web of tunnels, caverns, shafts, underground lakes, and ancient worked passages.
The Silt Thread, Blue Furnace Lake, The Lower Run, Glasswater Reach
Borders
Upper shafts that open beneath distant surface lands
Abyssal chasms that divide the central reaches
Flooded lower passages beyond known maps
On the road
Reliable travel depends on guides who read airflow, mineral marks, and fungal growth.
Flood surges can erase familiar paths within hours.
Magnetic anomalies and living crystal can distort compasses and spells.
Landmarks
Thir'Nosh, an ancient machine womb revered by the Qhacret.
Rootcore crystal seams that glow faintly before a storm of magic.
Crystalline cathedrals that carry sound across enormous distances.
Sealed doors whose mechanisms pulse like sleeping hearts.
Landforms
Vast vaulted caverns
Basalt ridges and broken shelves
Sinkhole shafts descending through many levels
Subterranean lake basins
Resources
Rootcore crystals
Geothermal minerals and workable alloys
Medicinal fungi and luminous moss
Freshwater springs
Power
Rule
GovernmentA loose compact of settlement councils, trade delegates, and custodial assemblies; local custom governs beyond their reach.
SeatAuthority is distributed among route councils and local chambers, with no single capital.
StabilityGenerally steady on established routes, but fragile where crystal claims, water rights, or machine sites overlap.
Laws
A marked passage may not be blocked without warning its neighboring settlements.
Rootcore veins require shared claims and limits on extraction.
No one may awaken an unknown machine without witnesses and a prepared escape route.
Water sources are protected from poison, blood rites, and industrial waste.
Factions
The Salt Orchard CompactTrade alliance
Influence: Strong along crystal routes and at major exchange chambers.Control access to Rootcore deposits while keeping extraction within agreed limits.
The Meadow RegisterQhacret custodians
Influence: Quiet but extensive near sealed ruins and Qhacret settlements.Protect old machines and determine whether the Deepways should be opened to surface powers.
The Westmere KinNaga confederacy
Influence: Dominant in flooded tunnels and feared beyond them.Preserve the hidden passages and prevent intruders from disturbing their waters.
Faiths
Root Below
Influence: Widespread among cultivators and route keepers, with local rites varying by settlement.The Root Below is honored as the source of growth, stone, and enduring memory.
Quiet Current
Influence: Strong among Naga communities and respected by travelers on flooded routes.The Quiet Current teaches that water remembers every passage and every trespass.
First Making
Influence: Central to many Qhacret communities and influential among machine wardens.The First Making venerates craft as a sacred act and treats Thir'Nosh as a place of origin.

History and secrets
The Deepways were already ancient when the first surviving route marks were made. Qhacret memory centers on Thir'Nosh, where they say the first Mage-Forged Guardian was born. Later collapses severed routes and scattered communities, while the rediscovery of Rootcore deposits restored trade. Each people preserves a different account of the old machines, and none can explain why some sealed chambers still answer to living minds.
Key events
Before the ledgers
The First MarksThe earliest surviving marks describe a connected world of caves, though no account agrees on who made the first roads.
The Foundry Age
Birth at Thir'NoshQhacret tradition holds that the first Mage-Forged Guardian emerged from the machine womb at Thir'Nosh.
The Severing
The Broken WaysA chain of route collapses divided old communities and left many passages unclaimed.
The Present Age
The Crystal ReturnNew Rootcore seams drew delvers back into the deep and revived exchange between distant chambers.
Secret 1 · GM only
The ancient machine works may be parts of a single planetary core rather than separate ruins.Found by: A chamber's crystal growth forms a repeating pattern that matches no natural fault.If found: The Deepways may contain a planetary intelligence capable of altering routes, magic, and the surface above.
Secret 2 · GM only
The first Mage-Forged Guardian may have been assembled rather than born, and its maker may still be active.Found by: At Thir'Nosh, a Guardian's oldest memory names a maker absent from every Qhacret record.If found: Proof could challenge the Qhacret origin tradition and change who claims authority over the machine womb.
Secret 3 · GM only
Rootcore crystals may be living components of the buried mechanism, not merely a natural resource.Found by: Rootcore veins grow toward sealed doors instead of following the surrounding rock.If found: Opening the doors could reveal new resources or destabilize the chambers and waterways above them.
