One planet, at real scale. One line of warmth, always moving.
Every continent sits on the same sphere. Every sunrise is a specific longitude catching the sun. Every lantern you can see from orbit is another settlement holding its stretch of night.
The Planet
Emberline is a single persistent planet, rendered at real-world scale and seeded with authentic elevation and geographic reference data. Mountain ranges, coastlines, valleys, and river systems correspond to a true spherical world rather than a tiled sandbox. A coastal fishing village, an alpine ruin, and a continental interior all sit on the same curved surface. You can walk, ride, or sail between them — no loading screens, no fast-travel shortcuts.
The horizon falls off the way a horizon should. Distance has weight. Travel is a commitment, not a fast-travel menu, and the sail from one coast to another is long enough that the sky changes underneath you. Environments layer into a seamless biome palette: warm sage overworld pockets, frontier homesteads around lantern-lit workshops, dense settlements with ceremonial plazas, coastal trade towns, highland passes, deep-forest sanctums, and ancient sacred ruins whose concentric floor patterns and prismatic portals are where the art goes furthest.
The world is a shared artifact, not a generated one. Wherever you arrive has been handcrafted or procedurally authored to feel earned. A tree you chop is where it is because somebody placed it there. A ruin is where it is because the geography conspired to put it there.
The Emberline
The planet's terminator — the seam between day and night — is a slow, continuous line of ember-colored light that sweeps forever across the surface. Sunrise on the eastern edge of a continent; sunset on the western coast. Always somewhere, always moving.
When the terminator crosses a region at dawn, that region experiences Dawnwash The in-world phenomenon of the emberline crossing a region — honey-gold light washing from horizon to horizon as night yields. — honey-gold light washing horizon to horizon as night yields and lanterns extinguish one by one. At dusk the reverse, Duskfall The emberline carrying night across a region, lanterns kindling in its wake. Dawnwash in reverse., carries night across the region and the lanterns kindle in its wake.
At night, the hemisphere facing away from the sun goes dark — but not empty. Settlement hearths, roadside lanterns, watchpost braziers, and shrine fires stay lit, and from altitude they form their own glowing line across the dark side of the planet. We call it the Lanternchain The visible network of settlement and roadside lanterns that lights at Duskfall. Renders as the 'second emberline' at altitude. — the second emberline, the one civilization holds through the night until the terminator returns.
Time, Weather, and the World Clock
Emberline runs on one authoritative UTC clock, shared across every player. It never drifts. From that clock the rest of the world follows: sun angle, moon phase, tide height, terminator position, lantern state.
Each point on the surface has its own local solar time driven by its longitude. Dusk on the dungeon side of the planet is dawn for raiders logging in from the other hemisphere. A storm rolls across a region at a believable speed. Tides rise and fall against the coastline, revealing ruins that can only be entered between waves. The moon walks through its phases, and certain ritual structures — moon-gates Ritual structures that only activate during specific lunar phases. — only come alive during specific lunar geometries.
Sacred geometry The latent mathematical pattern of the world, most visible in ruins, around relics, in moonlight, and in night fog. Expressed through radial symmetry, concentric rings, and polygonal ornament. is latent in all of this. It is most visible in ruins, around relics, in moonlight, and in night fog — the world revealing a little of its underlying math only at certain times, from certain angles, under certain weather.
The world is the stage. The players who cross it are the Motes — faceted, featureless, lit from within.
