Act 1 - Utopia

With biomes ranging from misty rainforests to arid deserts, Erpo was a sight to behold. Its people, although of the same race, could not be more distinct in terms of culture.
In the infancy of Erpo, its inhabitants wandered from their common homeland to continents spanning the far reaches of the world. The inhabitants, regardless of which continent they inhabited, lived a life of peace and wealth.
However, certain scientists feared that this prosperity would not last. They predicted that Erpo would be devastated by a mass-extinction level event and scrambled to formulate solutions to survive the impending calamity.
