〘 Nythera 〙

The world does not revolve around kingdoms.

It revolves around what waits below them.

Seven known Abysses. Seven cities built on risk. One world shaped by descent.

〘 World Codex 〙

Nythera is a medieval fantasy world where Humans, Elves, Dwarves, Beastkin, and Demons live in the shadow of the seven known Abysses.

These are not ruins to clear and forget.

They are permanent wounds in the land; immense layered depths filled with creatures, rare materials, unstable anomalies, and relics that do not belong to any known age.

Around every Abyss, a city has risen.

Around every city, ambition follows.

〘 The Shape of the World 〙

Abysses

All Abysses descend in layers. All grow deadlier with depth. All are believed to end somewhere far below. None are fully explored.

They do not trap those who enter them.

They simply test whether leaving is still possible.

Pockets

Within the depths, reality sometimes misbehaves. Pockets, also called Alcoves, appear as rooms, corridors, ruins, or enclosed spaces that should not exist within the surrounding stone.

Some vanish in minutes. Some endure just long enough to change a life.

Relics

Relics are the prizes most divers dream about and the reason many never return the same. Their origins are unknown, their effects are inconsistent, and their value is decided only after Guild appraisal.

〘 The Seven Abysses 〙

Each depth leaves its mark on the city above it.

Veyrth

The unstable Abyss. Shifting routes, spatial irregularities, and the highest known Pocket activity make Veyrth the dream of relic hunters and the grave of the overconfident.

Veyrth City thrives on speed, trade, and dangerous opportunity.

Sylvaris

The living Abyss. Dense overgrowth, toxins, predatory flora, and biological threats make the environment itself the enemy.

Sylvaris City is a center of alchemy, research, adaptation, and careful preparation.

Kharvok

The industrial Abyss. Stable routes, rich ore veins, and high extraction value make Kharvok the backbone of material supply across Nythera.

Kharvok City is built on industry, logistics, and sustained output.

Velmora

The silent Abyss. Low visibility, muted sound, and constant psychological strain turn even simple movement into a source of dread.

Velmora City values discipline, control, and strict operational order.

Pyroxis

The volatile Abyss. Heat, pressure, unstable terrain, and environmental spikes make survival a matter of timing as much as strength.

Pyroxis City is defined by engineering, reinforced infrastructure, and hazard management.

Thal’Varan

The structured Abyss. Corridors, chambers, and ruin-like formations create the illusion of design without any confirmed builder.

Thal’Varan City is the world’s center of relic study, records, and methodical analysis.

Nythral

The deepest Abyss. Its defining threat is not a single hazard, but escalation, endurance, attrition, and the cost of going farther than anyone should.

Nythral City exists for long-form expeditions, elite factions, and those willing to measure ambition in survival.

〘 The Guild 〙

The Abyss Divers Guild is the only power recognized across all kingdoms as the regulator of legal Abyss access.

It exists so no single nation can claim an Abyss for itself.

It registers divers, issues licenses, oversees job boards, appraises relics, processes monster materials, and tracks rank progression across all Abyss activity.

Rank does not decide whether you may enter an Abyss.

It decides which official work the Guild trusts you to survive.

Within this system, divers may form lasting groups called Factions or Families, building their own influence, resources, and reputations beyond individual rank.

〘 What Drives the World 〙

Nythera’s economy is built on risk converted into value.

Common jobs, resource extraction, and monster materials keep cities running. Relics create legends, rivalries, and sudden wealth.

Near Abyss Cities, prices rise with demand. Inns stay full. Gear moves quickly. Information sells almost as well as steel.

In a world like this, danger is not an interruption to daily life.

It is part of the infrastructure.

〘 The Old Ruin 〙

Nythera was not always shaped by the Abysses. In ancient history, two gods ruled over the world until their ideological conflict became a divine war that nearly destroyed civilization itself.

When one god destroyed the other, the released power sank into the land.

The Abysses are what remained.

〘 Your Role 〙

You are not forced into a single path.

You may descend as a diver, climb the Guild ranks, hunt relics, build a faction, study anomalies, chase wealth, survive city politics, or stay away from the Abysses entirely and still live in a world altered by them.

Nythera gives you structure.

What you do with it is yours.

〘 Current State 〙

World Scope: Open-ended and system-driven.

Core Pillars: Exploration, Guild progression, relic discovery, faction growth, trade, survival, politics, and freeform roleplay.

Known Regional Hubs: 7 Abysses and 7 fully defined capital cities.
