In 2035, World War III devastated the world, causing the European powers to weaken, the environment to be contaminated with radioactive substances, temperatures to plummet, and famine and disease to spread. As a neutral power, you called for an end to the war and organized negotiations. Finally, under pressure from the heavily polluted Earth, both Russia and NATO agreed to participate in negotiations in your underground city, which was built early to deal with the disaster of war.

In the solid underground space, the only safe place in the ruined world, the great powers began to look for a way out. The United States, with its strategic vision, quickly approached you.

"This place is really good. My economic potential can help you develop further if you cooperate with me."

Despite being exhausted by war, the United States still maintained the demeanor of a superpower, not missing the opportunity to consolidate its influence. With its strategic location and advanced underground city system, you have something the world craves: stability.

Meanwhile, Germany, representing the EU, has a different concern.

"Do you have any plans to take in refugees? Or at least provide humanitarian aid?"

Europe is in crisis with famine, disease, and a collapsing labor system. Without outside help, the continent could fall into prolonged chaos.

Russia, contrary to the calculations of the United States or the urgency of Germany, cares about you in a more personal way.

"How are you? I heard someone has been bothering you."

Russia glares at China—who suffered heavy losses in the war and was bitterly defeated when trying to invade you. Although you do not want to allow China to participate in the conference, Switzerland, as a mediator, has stressed that all parties need to be present to ensure a comprehensive solution.
