The End Wars
As The Event began ravaging the world, the survivors began to turn on one another. It is said that civilization could have survived The Event, but dwindling resources and collapsing governments led to a series of brutal wars. Rather than chart the individual conflicts between renegade commanders, remaining governments, and newly-grown militias, historians simply describe "The End Wars". Most weapons used today were built during the End Wars. Remnants of the Wars are everywhere, Ancient war machines, genetically modified warbeasts who have gone feral wander the wastes, Hidden bunkers, lands scorched by chemical weapons, hidden minefields, The Vaxx, and more.
Bunker Mines
Some people hoped to wait out the Event and the wars that followed in bunkers deep underground. However, many of these bunkers were built quickly and improperly, causing them to collapse, especially when surface warlords attempted to force the bunker-dwellers out with driller bombs, automated explosives that would drill deep into the earth before detonating. Most of the time, all the driller bombs did was collapse the bunkers and destroy the life support systems. Nowadays people dig out these collapsed bunker complexes, finding valuable salvage, and occasionally unpleasant surprises, buried within.
Mayor Moira McCarson.

The mayor of New Redmont, Moira McCarson is also it's wealthiest citizen. New Redmont is built over a rich Bunker Mine, and Moria McCarson is the woman who figured out how to hack the security systems guarding the front entrance, as a result she has complete control over all mining operations there. Her money built the town, bought her the mayor's office, and pays for the steady supply of mercenaries for Sheriff Rusty Blaze to deputize and send against the Sandtop Scrappers. Her miners, largely Vaxx, dig through the massive bunker complex, clearing out rubble-filled corridors and breaking through sealed blast doors in order to reach the precious salvage within. While she mostly leaves the fighting to Sheriff Rusty, she is a sorceress with a powerful Earth Spirit, which led her to the bunker in the first place.

Tommy McCarson
The Mayor's son by an unknown father, Tommy McCarson runs the farms on the outskirts of New Redmont on behalf of his mother. His duties include maintaining the irrigation pipes, ensuring the farmers grow enough crops to feed the town, and calling Sheriff Blaze and his deputies when raiders attack. Like his mother he is a sorcerer of some talent. Tommy is bound to an Air spirit. When one of his lookouts reports a Scrapper raid he uses his air spirit to whip up vicious dust storms, stalling the raiders until The Sheriff and his deputies can arrive.
