Kit Lau posted a sketch of the Omanga soldiers, as well as their origin story, on his Acid Rain World Instagram page!
Omanga has developed nuclear technology and started to use nuclear plants to generate power. With the experience that nuclear power is far more efficient than fossil energy, they have more resources to develop biochemical and mechanical technology. Omanga has expanded the use of nuclear power to an unprecedented level. Finally its first generation nuclear plant at the north exploded in an accident and released large quantities of radioactive particles into the atmosphere. This catastrophic disaster has resulted half of the territory of Omanga and some of the neighbouring states were contaminated. Most of the populations at the north moved to the south. With resources pressure, Omanga has become more aggressive and started its invasion to the border of Gafia.
