Enter a unique world where a handful of survivors settle on the back of a powerful creature – onbu. It's up to you to lead this community, expand your village, and form a unique bond with your host to face the threats of a post-apocalyptic planet together. Build, develop, and manage your settlement in unusual conditions. The limited space on the back of onbu requires a well-thought-out strategy, production optimization, and wise resource management. Decide whether your people will live in harmony with the creation or use it solely for their own benefit.
