Planet Eldra

The distant Planet Eldra. This world was once covered in endless grasslands. Herds of great beasts treading the earth, shadows of wings streaking the sky, bioluminescent trails glowing in the darkness — countless lives intertwined, and the planet breathed as one living organism. But the balance collapsed, and the land fell silent. You are the one who will breathe life back into this world. Release herbivores, introduce predators, cultivate decomposers. Eat, be eaten, die, return to soil, and sprout anew — restore that cycle to this planet once more. —————————————————— Once placed, the creatures begin to act on their own will. They graze, hunt, breed, and eventually return to the earth. Even without your intervention, the ecosystem shifts moment by moment. But life is never so simple as to "work itself out." Too many herbivores, and the grasslands vanish. Without predators, reproduction spirals out of control. Without decomposers, the land rots from within. Vegetation and soil, weather and plague, birth and death — amid this web of interconnections, what you seek is "stability" — a fragile miracle. ● Unique creatures with autonomous AI behavior ● Real-time simulation linking vegetation, soil, and weather ● Gene tuning to adjust lifespan, fertility, and resistance ● Diverse stages unlocked progressively, plus Hard Mode ● Concept art and detailed creature encyclopedia There is no single right answer. Build your own ecosystem on Eldra.
