The Mist Alliance was different from other mega empires in that it wasn't an independent country. The Mist Alliance was an alliance of many Northlands countries.
The Northlands sevem countries which the ruling human society had viewed as barbarians were the core of this alliance. Non-human species were also a significant part thereof. As the Underground, Xiluo undead, Northlands beastmen, and Northlands elves all gradually joined the Mist Alliance, this naturally transformed the nature of the Mist Alliance. Humans were no longer the core of the alliance.
What helped maintain the Mist Alliance, however, were the two countries of the People of the Mist, Sleuweir and the East Mist Communal Country. These two kingdoms were the political core of the Mist Alliance, and they were also faintly seen as a brand-new Mist Kingdom.
