Earth-72

Earth-72 is a reality in the multiverse. It's Earth is currently controlled by Vampires, who have largely subjugated the human species, though there is some resistance to be had.

History
At some unknown point, Vampires from Earth-50 (AKA Caathix), found a way to this universe's Earth and migrated there. While some Vampires opted to peacefully insert themselves into human societies, most saw the humans there as nothing more than a resource to be exploited. After a prolonged period of turning humans into Vampires and using them to infiltrate various governments and world powers, the Vampire race eventually took control of most of the planet, and have retained that control to the present day.

Setting
Despite what one might assume, not all Vampires are the same, nor are they all wicked. In fact, some societies see relatively successful and peaceful human-vampire integration, though even here humans tend to be treated as second-class citizens who lack the full range of rights and privileges held by Vampires.

Other places, on the other hand, are hellish dystopias where Vampires lord over their human populations without mercy. Contemptuously viewing humans as nothing more than sources of food or a means of spawning new Vampires, they keep humans imprisoned and penned like cattle and treat them little better. Even Vampires who were once humans are looked down upon in these highly elitist societies, which consider Vampires born from other Vampires to be inherently superior to those created through other means (even though virtually all of these Vampires trace their lineage back to former humans at some point, rendering their supremacist attitudes rather hypocritical).

Finally, there are the places that are in the middle, where Vampires are dominant and make sure the humans don't forget it, but also permit them more freedom, autonomy, and basic rights and dignity than the worst places, provided they remember their place and don't get too uppity or insubordinate.

Not surprisingly, most of the humans on this Earth do not take kindly to being reduced to second class citizens at best and chattel at worst, and there are many resistance movements to the Vampire's rule throughout the globe. Some, such as the Human-Vampire-Coalition (or the HVC), argue for peaceful coexistence but also stress humans having equal rights to Vampires, rather than be subservient. They have some traction in the most tolerant communities but still face an uphill battle (one they wage largely with nonviolent protests). The rest of the societies though, are hostile to their message, and the worst consider them terrorists deserving of extermination, and in these places the HVC's methods cease to be nonviolent out of necessity.

Besides the HVC, there's also the Human Liberation Front (or HLF), that is mostly concerned with ending Vampire tyranny in the most intolerant societies. They sometimes work with the HVC and mostly respect their idealism, but their primary goal is stopping the Vampire's sadistic predation and oppression of normal humans, and consider an egalitarian utopia a goal for another day. Finally, there's the more radical Hellhound Brigade, whose members are a mix of those who earnestly believe in protecting humanity from Vampires as the HLF do, and those who are outright genocidal in their hatred of Vampires and believe that they need to be exterminated wholesale, even Vampires who haven't done anything wrong. In the middle are many other members who are also prejudiced, but not to such an extreme degree. While not uniformly wicked, the Hellhound Brigade is still the most extreme, ruthless, and controversial one on the whole, and many of their actions are considered terrorism not just to Vampire dictatorships, but the more tolerant societies as well. They sometimes work with the HLF (especially their more mild members who are not genocidal or prejudiced), but the HVC makes a point of disavowing them and refuses to work with any but their absolute most mild members (and even then try to convince them to abandon the Hellhounds and join the HVC).

Finally, Vampires are not the only race that migrated to Earth-72. Some number of Lycanthropes, mostly Werewolves, also came to this world alongside Vampires they worked with or for, and have since spread Lycanthropy to enough humans to sustain a sizable population. Hated and feared by both many humans and Vampires alike, Lycanthropes have an uncertain place in this world, and pick their allies carefully.

Regions of Note

 * New Haven: Created fairly recently after the unfortunate collapse of the original Haven, New Haven is an optimistic experiment in tolerance, where humans and Vampires co-exist relatively peacefully and attempt to respect one another's rights as much as possible. The failure of the original Haven and the general tensions between Vampires and humans around the world makes fears of New Haven failing high, but its population is determined to prove the skeptics wrong. True to their name, they shelter many members of the HVC and HLF. They tolerate members of the Hellhound Brigade provided they do not cause trouble, but are wary and distrustful of them due to their more hostile attitude to Vampires.
 * Oasis: Another of the more tolerant societies, and one that is a major agricultural and export center. This makes them valuable to the other societies, allowing them a lot of leverage in dealing with other societies and in turn promote their more egalitarian worldview. However, while Oasis is itself egalitarian, it is willing to trade with societies that are less so, to the outrage of many within Oasis who feel it to be a betrayal of their principles to deal with those who do not share their values of tolerance. And while Oasis is confident that societies like the Necropolis will behave themselves as long as Oasis has things they want, many fear that they underestimate the lengths that such societies will go to get what they want on their own terms and not those of the Oasis.
 * Blud: A poor, run-down, and crime-infested city, Blud is seen by others as a dumping ground. A place where societies like the Necropolis and Red Moon Metropolis put their trash. And by "trash" it is also meant undesired people and not just rubbish. While people in Blud generally do not care if one is Vampire or human, it is more out of apathy than egalitarianism. In Blud, virtually all are corrupt, from police patrolling the streets to judges and above. Gangs hold the real power in Blud, with little serious enforcement of many laws. However, while crooked judges and dirty cops may be content with this arrangement, citizens are not. As the mobs become more brazen and brutal, many people, tired of nothing being done, turn to vigilantism. Simply put, the situation in Blud has become untenable. Heroes are needed in this city, and as soon as they can be acquired.
 * Red Moon Metropolis: One of the largest and most prosperous Vampire cities in America, Red Moon Metropolis also reflects starkly the clear inequalities between Vampire and Human. While the latter do strictly speaking have basic rights and autonomy and are not just preyed upon or treated as farm animals, their political power is virtually nonexistent, and attempts to gain any or assert themselves are often met with apathy at best and cruel repression at worst. Police brutality is not uncommon, and, to quote a popular saying: "You don't see a Vampire waiting a table for a human in Red Moon Metropolis." With all attempts by humans to improve their station having been met with stonewalling and failure, many fear that the situation will soon reach a boiling point, and that when it does, the consequences will be terrible indeed.
 * Necropolis: Undisputedly the most horrific and repulsive major Vampire population center is the Necropolis. Located in Greece, the Necropolis is ruled by Vampires who are "old-schooled" in all the worst ways. Contemptuous of humanity, Vampires in the Necropolis see them as nothing but food to be devoured or breeders with which to produce children, and even the latter are looked down as inferior to "pure" Vampires. While they do stop short of slavery or genocide, the motivation for the latter is pragmatism and the motivation for the former more a desire to give jobs to their own kind. In all, the Necropolis is such a vile place for humans to be that it is often called "the place humans go to die." With most humans having by now abandoned or fled Necropolis, or else members or allies of the HLF and Hellhound Brigade (both of whom wage non-stop war on the Necropolis), their human population is very small relative to other Vampire population centers, leading some in the Necropolis to argue improving conditions for humans just a little, if only to incentivize humans to come back so they can continue to have a reliable food source. So far, these "reformers" have had little success in convincing their fellows of the wisdom of their idea.
 * Demon's Tooth and Demon's Hook: A pair of cities in the United Kingdom that like Necropolis represent Vampire intolerance towards humans at its worst. However the manner of the cruelty is somewhat different than Necropolis. Where Necropolis treats humans as nought but sources of food and breeding, the Demon's Tooth and Demon's Hook instead consciously keep their human populations in a state of destitution. They see no need for pens, reasoning that if humans are impoverished and defenseless they can prey on them easily at will anyhow. And as for breeding, with many humans desperate enough to turn to prostitution, many Vampires negotiate contracts with these individuals, giving them substantial salaries in exchange for getting any children born from such unions. Desperate as they are, and not generally wanting any children with Vampiric blood in any case, most prostitutes agree to these deals. And so life for humanity in Demon's Tooth and Demon's Hook remain miserable and bleak. Members of the HVC have attempted to convince the downtrodden people in these cities to stand up for themselves and demand better treatment, but unfortunately the more militant Hellhound Brigade has also found extremely fertile ground for recruitment from scores of people suffering here who are not interested in compromise or co-existence; they want payback.
 * The Red Legion: China's ruling Vampire government. Called "Jiangshi", China's Vampires are somewhat distinct from their American/European counterparts, but no less lethal or cruel. Sadly, China's government did not become democratic after the Vampires took over. Instead, those who "disappeared" or were sent to "reeducation" courtesy of the government now often find themselves providing their Vampire overlords with a good meal as punishment for their defiance or dissent. They are on friendly terms with the Necropolis and the rest of Europe's more brutal Vampiric governments, as well as many of America's. So much trade has kept the Red Legion wealthy and prosperous, but it also means that authoritarian and oppressive Vampiric governments are a somewhat united front, thus hindering efforts to reform or overcome them.
 * The Underworld: Once a large American city, the place that would become "The Underworld" was destroyed by a massive earthquake. Entire buildings fell into the chasm created by the geological disaster, and when it was all over, a new city was built over the ruins of the old. What had once been was left where it had fallen, and thus, the name "Underworld" came to be adopted to describe the ruined metropolis that lay beneath the new. What people did not realize at first, was that a great many had actually survived the earthquake but been lost in the chasm. Unfortunately, Vampires soon swarmed into the area, finding the darkness and subterranean environment much to their liking. Few of these were "true" Vampires though; most were the various wretched and degenerate sub-races. Either way, they soon killed or turned nearly all of the humans in The Underworld, and those who came down from the surface met similar fates. While it would seem prudent to clear the Vampires out of the area, so far this has not happened, as none seem to have the heart to devote the resources and manpower needed to make such a venture work. And so the Underworld continues on, a dark, miserable place where Vampire-Spawn, Alba-Fende, and the occasional "True" Vampire run wild and unopposed, making it a death trap for normal humans.
 * The Great Den: The closest thing that Earth-72's Werewolf population has to a central hub or any kind of community in which they are the majority. Congregating in large numbers for protection, the Werewolves are wary and suspicious of outsiders, but generally permit them so long as they are not looking for trouble. Due to the high concentration of Werewolves, their city is designed in such a way that it goes on "lockdown" every full moon as huge swaths of the populace turn into their Werewolf form and so need to be contained lest the entire city devolve into chaos. As not all Werewolves turn with the full moon, it is up to these particular ones to keep the wheels of the city turning those nights the rest of their community are locked up for their own safety and everyone else's.
