History
The Federation of Mugen was a tributary state of Nikan during the reign of the Red Emperor. Though the Nikara believe (and are taught) that Nikan brought culture and civilization to Mugen, relations between them were never peaceful and always involved skirmishes and disputes of some regard. When Nikan dissolved into internal warfare after the death of the Red Emperor, the Mugenese took the opportunity to attack and invade it. Being a highly militaristic country, rapidly progessing in terms of both technological advancement and population, the well-trained Mugenese soldiers defeated the fractures forces of the Empire easily and won this First Poppy War. They occupied the eastern provinces of Nikan, namely Snake Province.

During the Second Poppy War, the Federation's militia became obsessed with the Speer lies and their shamanic abilities, seeing them as sources of alien superpowers, and set up numerous human experimental camps along the coast of the Snake Province to test on captured Speerlies.

The Nikara Empire regained its independence from the Federation at the end of the Second Poppy War through the aid of Hesperia's naval army and the Trifecta.

At the beginning of the Third Poppy War, the Federation of Mugen was led by Emperor Ryohai. They declared war on Nikan during the events of the first novel. They successfully attacked Sinegard, the capital, and progressed inland to Golyn Niis through a secret pass in the Kukhonin mountain range. The Mugenese commit genocide and mass rape against soldiers and civilians alike.

The Mugenese forces continued to progress north, towards the Empress' secret palace. However, a faction of soldiers—tipped off by the Empress Su Daji—attack and capture Altan Trengsin and Fang Runin at the Chuluu Korikh. They are then taken to the old Mugenese human experiment camps in Snake Province, from which they eventually escape, Trengsin committing suicide in the process.

The entire nation of Mugen was decimated abruptly with a volcanic eruption triggered by Fang Runin and the Vermillion Phoenix of the South. Aftwards, the remaining Mugenese (mostly soldiers) in Nikan become roving bandits and murderers in the southern provinces.

Parts of the archipelago survived but have fallen into anarchy due to the sheer destruction of the main island and death of the emperor. The remaining soldiers and government officials on the homeland have focused on restoring the peace, leaving the soldiers on the mainland on their own. Refugees from Mugen have started arriving on the mainland.
