Welcome to the world of Arborea, where a cataclysmic event destroyed most of its former fertile lands, and scared all the Creatures living on them. You are a Patron Spirit, guiding your Villagers to heal and regrow the landscape around them by sending them on Pilgrimages to build your personal Ecosystem. You will regenerate forests, meadows, rivers... in order to create an attractive Ecosystem for several Creatures to make it their homes. Creating the perfect environment for those Creatures, while trying to satisfy the challenges each Season will bring, will reward you with many Regeneration Points (RP). Your actions will heal your lands, and if you manage to gain the most RP in the process, you will win the game.
