Compliance.
The desire of every authoritarian who inflicts their will unto the masses.
The year is 2105. A dying and contaminated planet has brought humanity to the brink. The inhospitable wastelands are punctuated only by small pockets of life where the descendants of mankind hold on to a world that can sustain them no longer.
In the city of Sanctum, one of the last and greatest bastions of mankind, the people force out their existence. Resources are in short supply, and life within the walls depends on purifiers that provide breathable air.
Citizens of Sanctum are ruled by the hard fist of Central. The fragile society dependent on complete obedience. All citizens must consume a mandatory drug called treatment, that inhibits all forms of aggression and discontent. Those who refuse are expelled from the city, left to slowly suffocate beyond its walls.
Those who comply live an utopian existence, free from worry and fear.
However, the leaders of Sanctum are making plans to expand the City walls, and in their way are the masses that they do not control.
There are too many crowding the walls, too many to bring to heel and force into compliance... for now.
