DenverDenver was abandoned by civilized folk, mainly because of lingering radiation and huge packs of wild dogs that had taken over the large city. These packs would swarm their prey and rip them to pieces. These dogs were fearless, continuing the fight no matter how many of their own they lost. Centuries of natural selection resulted in Denver hounds becoming incredibly potent killers. A tribe of people learned how to live with the dogs, treating the feral hounds as spirit animals, companions in the post-nuclear world.
Between 2277 and 2281, the Caesar's Legion came. The Hangdogs, the tribe that tamed the wild dogs, were assimilated and their culture wiped out, while Denver became a Legion territory. The cost was steep, however, as the Legion lost many men to the savage canines. In 2287, the Hangdogs and their feral pets clashed with the Legion once again. This time the results were different and much more brutal. Both sides suffered innumerable casualties. This resulted in the Hangdogs retreated from the city and the Legion also leaving the city. The number of feral dogs in the city has since declined, making it safer for smaller settlements to have been set up.
Colorado SpringsColorado Springs was one of the Colorado sites responsible for extensive FEV testing. It was also one of the sites of Nuclear testing. When the Great War happened, one warhead was designated for Colorado Springs. The warhead hit about a mile out of the town epicenter, but still, the blast radius and radiation radius was enough to wipe out all who were living in Colorado Springs. Tens of thousands of people, gone. With the packs of feral dogs living in downtown Denver, many survivors from the area had made their way to Colorado Springs. That was a mistake.
Within a fifty year window after the Great War, the FEV virus had managed to escape from the lab it was in, infect the nearby wildlife and survivors, and then mutate. Colorado Springs was a hotbed of mutants of all kinds for the first hundred or so years after the Great War. And then came Caesar's Legion. On their way to Denver, the Legion made a stop at Colorado Springs. They came face to face with the greatest horrors of the FEV virus and the Battles of Colorado Springs ensued. After six months, the Legion had successfully diminished the mutant population of Colorado Springs and forced what was left into the depths of the Wastes.
After the Legion left Colorado Springs, the mutants returned, but not in force. There are now sparse hot zones in Colorado Springs which are home to mutants, but those areas are underground or on the outskirts of the city. In inner city scavengers and traders set up shop. Now, Colorado Springs is mostly known as a trading hub with a dangerous underbelly. The inner city has a sentry wall and outposts along it to keep raiders and mutants out.
PuebloAfter the Great War, Pueblo became the hot scene for survivors. Word had gotten to them that the survivors who went to Colorado Springs had become mutated monstrosities and that those who went to Denver were torn apart by dogs. So Pueblo seemed like the best option for those in the area. It was a safe option. Three small settlements were set up in and around Pueblo in the beginning. These settlements protected each other and traded goods with each other. Then, after many successful years of this, they merged into one big town. Pueblo attracted all kinds of people. Traders, ex-Raiders, Mercenaries, Scavengers, and survivors.
When the Legion came knocking on Colorado's doors, they overlooked Pueblo. Word had reached the city that the Legion was on it's way and that they meant business. So for the months leading up to the Legion arriving in Colorado, Pueblo began stocking it's arms. By the time the Legion entered Colorado, they had heard of the army that Pueblo had created and that they would fight to the death. The Legion passed by Pueblo without incident.
Now Pueblo has lost some of it's population to Colorado Springs, but it is still abuzz with activity. Pueblo is a safe city to live in. Relatively safe.
Fort CollinsFort Collins was a military base Pre-War and actually housed it's own fallout shelter. When the Great War happened and the first warheads struck the United States, Fort Collins shut it's doors. All activity in the Fort disappeared into the shelter. There are giant walls and security fences that surround the facility, they have not been penetrated yet by any scavengers or raiders. There is a lot of superstition that surrounds Fort Collins. It is known as a ghost town. No one has received word of survivors leaving the fallout shelter in the Fort, so most assume that they are dead or are ghouls.
Fort MorganFort Morgan, much like Fort Collins, had a fallout shelter and the soldiers used it. After the warheads hit and the dust settled, the soldiers and civilians in the shelter left to try and find other survivors. They ran into mutants and heavy levels of radiation, so they quickly made their way back into their shelter. Acting much like a Vault, the shelter protected it's denizens from the outside world and safely locked them inside. Thinking that they were the only survivors, the people inside of Fort Morgan began to reproduce to try and restart the world population. Their population swelled and they were forced to leave the shelter after 120 years.
When the survivors of Fort Morgan left their shelter, they were welcomed into a slightly less hostile world. That being said, they listened to their forefathers about the dangers of the Wastes and decided to instead, fortify the rest of the Fort. Fort Morgan is now known as a very secretive community, as well as an arms powerhouse. They have the means to defend themselves.
TrinidadThe town of Trinidad became an interesting one shortly after the Great War. Survivors from the northern parts of Colorado had made their way down to Trinidad to avoid the mutants in the north. Eventually Trinidad, which was hit by no nuclear warheads, became a safe haven for many. It became a trading hub and home to many caravaners. The leader of the city, The Mayor, helped erect a small wall around parts of the town to keep out riff-raff. Things were going good.
Things took a turn for the worse when the Legion arrived. They came from the South and ran right through Trinidad. Those who resisted were either hanged or put to the cross. Trinidad, for many years, had hanged people and crucified people on it's outskirts. The once peaceful people of the town were now slaves to the Legion. Then another bad guy appeared to save the day. A band of raiders, a rather large band of raider clans, arrived from the west and waged an all out war against the Legion for Trinidad. After years of bloodshed, the Legion finally accepted defeat and retreated to the north. Trinidad was liberated, for the most part. The slaves were set free, all of them. The raider clans however, took over Trinidad and turned it into the mecca for sin. Whorehouses, bars, casinos, drug dens, all kinds of scum arrived in numbers to live in Trinidad. Some of the free slaves stayed to partake, some left.
The war took a huge toll on the number of raiders. Trinidad does not have a huge permanent population, but it does have a revolving door of satisfied customers.
Grand JunctionAfter the Great War, Grand Junction was abandoned by all. For almost 150 years, it was empty of all human life. That being said, Ghouls took over the city. At first it was just sparse packs of feral ghouls. They came in from the east, crossing around the mountains to reach Grand Junction. They took up home for awhile in Grand Junction and Scavengers noted it as a place to avoid due to the number of ghouls roaming around. Eventually however, non-feral Ghouls sought refuge in Grand Junction. They eliminated the feral ghoul population and forced the stragglers out into the Wastes.
Now Grand Junction is home to a large concentration of Ghouls.
