In the International Underground World, there are many forces.
Ancient families, financial conglomerates, mercenary groups, assassin organizations, Mutant Alliances, Mutant Companies, and so on.
Each power is a sovereign in its own right, entrenched in a specific locality, declaring themselves kings and overlords, just like the feudal lords of ancient times!
There are even some Mutant Organizations that have established their own nations, becoming the rulers of those countries.
Sestan is precisely such a nation.
Located in South America, Sestan is a medium-sized country, with a land area of 600,000 square kilometers and a population of over 3 million.
As an island nation located near the South American continent, Sestan enjoys a unique geographical advantage.
Its tourism, shipping trade, and agriculture are exceptionally developed, and the standard of living for its citizens is very high; naturally, the Sestan government has a lot of money.
