01
Ancient Woodlands
Old-growth forest with moss-deep floors and spring-fed streams, where Glowing Chipmunks build and repair their dams.
The World
A valley that runs without you
Every playthrough is a seeded world: its ridges, rivers and forests, and the animals that live in them, follow the same rules whether you are there to see it or not.
Regions
Four places, four ways to survive
02
Windcarved Highlands
Ridges and cliff shelves above the valley, home to Sky Ibex and the wind that shapes them.
03
Tidal Marshes
Reed beds and shallow water that rise and fall, stalked by Marsh Herons; watch where you wade.
04
The Rainforest
A layered canopy of fig towers and liana bridges where primate troops live, feed and glide.
Systems
What makes it feel alive
Water that behaves
Rivers, groundwater and tides are simulated. Rain feeds the water, floods spread across low ground, and chipmunk dams hold, breach and erode.
Weather with weight
Clear, overcast, mist, rain and storm move across the whole map. Rain soaks you and the ground; shelter keeps you dry.
Fear and temperament
Animals react to harm, fire, light, noise and bigger predators. How bold or skittish each one is runs in its family.
Predators and prey
Hunts happen with or without you: stalking, chases, kills and carcasses that feed the next animal along.
Primate minds
Dusk Apes remember how you treated them and tell other species. They use tools, set snares and throw stones.
Your research camp
A comms tower whose signal follows the terrain, a power grid, building with real stability, and supply orders by radio.
Rain since noon. River up a hand’s width. Moved camp kit to the ridge.
Field guide
The species of the starting valley
Animals belong to anatomy families, and their genes shape the bodies you see: no two are quite alike.
Pack predator
Lumen Wolf
Hunts in coordinated packs; its markings brighten when it is close.
Dam builder
Glowing Chipmunk
Dams streams; floods and erosion change around its work.
Troop primate
Dusk Ape
Territorial at dusk and dawn, with real troop tactics, tools and snares.
Canopy glider
Lumen Spidermonkey
Roosts in colonies; its membrane’s light carries the colony’s signals.
Indicator species
Glass Salamander
Translucent and fragile; where it thrives, the water is clean.
Wading hunter
Marsh Heron
Patient, still, and very fast when it strikes.
Cliff browser
Sky Ibex
Guards its ledges; follow it and you will find the best paths up.
Burrowing herbivore
Stoneback
Roots and tunnels through the forest floor.
Small grazer
Bristlekin
Quick, wary prey that keeps everything else fed.
Ambush hunter
The Walker
Waits dark and still in the trees above the water. Do not stand under it.
