In the first few years, many cities faced destruction from contaminated radiation and unpredictable weather conditions beyond imagination. Moreover, there were stealth attacks from unwanted entities and conflicts between cities, particularly over land and resources. It took them several more years to reach a settlement.

​

           One part of the city-states signed a treaty to form the Nomadic Confederation, agreeing on economic aspects, stability, and scientific advancements. They also united their forces to negotiate with other kingdoms. However, despite their alliance, fierce competition and rivalry persist among them. 

​

           Amidst these city-states, there emerged a newly founded city that quickly rose to prominence as one of the most prestigious cities within the Confederation. This city is known as the 'Gate of All Nations,' renowned for its mercenaries who never fail, meticulous in their job selections. This rapid growth was also fueled by a governance policy emphasizing equity. Before long, many desert nomads were drawn to join their ranks, forming a large family. Consequently, the Gate of All Nations expanded into a medium-sized city with high potential, prompting the Confederation to consider bringing them in as a member.
