Revision 1

Overview

Setera is the primary setting of Chrono Odyssey and one of twelve planets created by Chronos, the god of time. Once a land of abundance and life, Setera now serves as the last line of defense against the Void — the ancient force that has already consumed the other eleven planets. The open world is fully seamless, using Unreal Engine 5's World Partition system to eliminate loading screens.

Cosmology

Chronos and the Twelve Planets

Chronos created twelve planets across the cosmos, distributing Arche — the fundamental energy sustaining the cycle of nature and life — unequally among them. Setera received abundant Arche, becoming lush and prosperous. Magellan received very little, becoming cursed with famine and desolation. This unequal distribution is the root cause of the universe's imbalances and conflicts.

Arche

Arche is the lifeblood of all organisms and shapes the state of nature itself. Its abundance or scarcity determines whether a planet thrives or withers. Setera's rich Arche reserves made it the most vital of the twelve worlds — and the most valuable target for the Void.

Geography

The full launch map is described as four times larger than the CBT1 test region. Confirmed biomes include grasslands, snowlands, swamps, forests, deserts, frozen valleys, coastlines, ruins, and pocket dimensions of warped spacetime.

Western Continent

Vibrant and diverse, with dense settlements, road networks, rivers, lakes, and mountains. The Western Continent serves as the hub for quests, trade, and story progression. The Frontier's military presence is strongest here.

Eastern Continent (Gulf of Dust)

A stark, fragmented region scarred with blackened voids and muted tones. The crumbling terrain hints at magical corruption or historical devastation, likely representing high-level or endgame content zones.

Key Locations

• The Citadel — Hidden sanctuary for Sentinels, existing within a rift between time and space. Serves as a cross-realm social hub where Sentinels gather. Contains gateways to different worlds. NPCs Baldur, Kaya, and Velia reside here.

• Ruins of Time — Where the player discovers the Chronotector in the prologue.

• Dawn Slope — A major settlement with crafting workbenches.

• Rodinia — A related planet, nearly consumed by the Void. Velia halted time there to freeze its destruction. Visitable in-game.

• Cliffs of Mima — Named landmark.

• Murkwater Fishing Spot — Named resource location for fishing.
