Keystone

Keystone — Ecology for Timberborn Beavers are nature's keystone species. Take their role further — caretakers of the land — and the whole map comes back to life. Bring water to every corner of the map, and life follows. Cattails fill slow side channels and fish thread through them. Birches line wet banks. Cattle graze established grassland; deer roam mature forest. Rocks pale under sun, darken in the wet. Dry land makes do with thin scrub and tumbleweed until water reaches it. Poisoned ground stays scarred long after the source is gone. Nothing is painted on the map and nothing is random. Underneath, the mod reads every part of your terrain — water, soil, plants, contamination — and the biomes form themselves from what it finds. Mature land takes in-game time to grow. Brief lapses heal. Sustained damage leaves traces. Your beavers feel it too — three new Nature needs join their wellbeing, met at shrines, lidos, and other nature-related buildings near healthy biomes. What it adds Eleven emergent biomes. Forest, grassland, wetland, river, lake, shoreline, cave, monoculture, dry, contaminated, badwater. There's no designation tool — each biome is whatever the map's conditions add up to. Around 70 plant scenes that bloom and decay with the map. Slow side channels grow spadderdock and cattails. Riverbanks pick up wetland-edge cover. Wet shorelines sprout birches. Drying land sheds its lush plants. Poisoned ground kills what's on it. Stone that responds to its conditions. Rocks go pale and dusty under drought, wet-dark along streams, sickly under badwater. Cross-faction flora. Plant the right conditions and the other faction's flora takes root on its own. Folktails playthroughs grow Iron Teeth species where they belong, and vice versa. No menus, no recipes — just the right ground in the right place. Morning mist over wetlands. Slow shallow water at the right depth wakes up wreathed in fog. Burns off as the day warms. Long-term ecological memory. Healthy land builds slowly
