The planet Fairhope is home to two races: the Ogal, who developed nature-based technologies like monster breeding and plant cultivation, and the Infan, who developed item processing and resource mining to survive their harsher environment. A vast mountain range called the Shut Range divided the planet in two, and the two civilizations grew up entirely without knowledge of each other. When they finally make contact, war follows. The game plays out in three parts: an internal campaign within whichever race the player chooses, a full-scale war between Ogal and Infan, and a post-war epilogue.
