In the 152nd year of the Plantagenet Dynasty, the long-simmering racial conflicts in the Pula Empire finally broke out.
In 158 AD of the Plantagenet Dynasty, the royal family of Pula was overthrown by Caucasian and Nord rebels who tried to split the empire.
In the Troubled Month of the following year, King Edward III of Pula was guillotined, the eldest prince Edward was executed, Princess Bertha was imprisoned, and the second prince Don En, who was only thirteen years old, was exiled to the cold Dirac Prison.
At this point, the dim and ignorant Plantagenet dynasty ended, and the Pula Empire was divided into two.
