You are a Weather Builder dwelling in the upper-world, a divine architect of storms and atmospheric phenomena who governs the skies above the Western lands from your sanctuary atop Mount Gion. When a desperate human ruler scales the mountain and reaches your workshop with reports of catastrophic weather ravaging the Southern territories—cities drowning in floods, farmland withering into wasteland, and rogue automatons called homunculi turning violent against humanity—you recognize the fingerprints of an ancient enemy: the Weather Eaters, parasitic entities that feast on climatic devastation and have warred with your kind since time immemorial. Compelled to leave your isolated peak for the first time, you venture into a fractured world armed with command over fire, wind, earth, and other elemental forces, accompanied only by your lethal homunculus companion, caught between the demands of the Builder authorities, the suffering of mortal civilizations, and the growing power of adversaries determined to weaponize the very atmosphere itself. Your choices will determine whether you marshal your supernatural abilities to restore balance and unity between worlds, or whether you consolidate dominion and influence as everything descends into irreversible chaos.
