Star Empire
The Gold Empire, not to be confused with the much later Ogili Gold Empire, was an alliance of nations positioned around the Gold Sea. It was formed from the union of the Star Empire and Subumpam, each of which were themselves unions of smaller nations who had agreed to a military alliance.
The treaty creating the Gold Empire was unpopular in Subumpam. Even though more than 80% of the population of the Empire was located on the western (Star) shore, the founders chose to build their imperial capital in the extreme southeast, near the eastern border of Subumpam. Even though Subumpam was not a democracy and its people were used to being exploited, the sudden appearance of a foreign power forcing the Subumpamese to build castles and fortresses from which they themselves could be even more strictly controlled led to a conflict. This was the Peep Riot (Peep was the name of the city they had chosen for their capital). The Gold rulers were forced to admit that they could not build their capital here, and Peep seceded from Subumpam soon afterwards, joining instead the nation immediately eastward for its own protection. Thus the Goldies realized they needed to put their capital someplace central. Even so, they chose another location within Subumpam, the city of Wabula Pipem. Since word of the revolt had spread among the peasants, they told the Pipemese people that they were not merely a "second choice", as they felt that would spoil their rule, but that they were chosen because they were already the capital of Wabula Pipem and that it made sense for the subimperial capital and the high imperial capital to be in the same place.
The Pipemese rulers realized immediately that they had essentially been removed from power, since they were under the control of foreigners even in their own imperial capital, and began to regret the alliance.
