Fractured Earth

World lore/information:

The Dark: A failed, or perhaps incomplete attempt at immortality. It forces the person that's infested to face their worst self(pride, greed, etc.). Corrupts any and all races if they are exposed for far too long. Seeing gore and other traumatizing will make you slightly less sane, and in turn expose you to the Dark.

Races:

Elves: the four Elven Tribes(the Wood Elves, Dark Elves, High Elves, and Nyxes[Nyxes live underground]) all specialized in a form of ranged combat and stealth before the Collapse. Most of the elves were corrupted by the Dark when the Collapse happened. The corrupted elves are now everywhere, attacking anywhere.

Dwarves: Former pioneers, engineers, and miners of the Dwarven Federation. After the Collapse, most of the dwarves retreated underground, where they all mostly died off due to starvation and the gradual entrance of the Dark Infestation to the underground. The awakened Dwarves, former dead dwarves, now roam the underground with their heavy weapons and drills.

Halflings: Once the master of defensive warfare. As the Republic of Aurore, with their extensive trench networks, massive magic artillery cannons, and their strategic location —hdden in a valley with only one chokepoint exit and entrance, they held off... For about two years. Then they ran out of gas masks, and slowly started getting corrupted. They had a pretty gruesome corruption too. Their corpses, known as "Shell-bearers", sprouted cannons on their backs.

Humans: The only semi-safe nation, they retreated to the skies and built "Babylon", 4 cities in the sky with their own purposes. The survivors of the other races are now refugees in the Neu Imperio(human nation derived from the ruins of the former human nation, the Gran Imperio)

Babylon's Cities:

Aeronochrona: The largest city that humanity built. The capital of Neu Imperio(the reformed human nation). Houses the greatest minds of the world. Located flying above the old palace of Gran Imperio.

Stratovorn: The Capital of Culture, the second largest city. Located above the Venusian Sea, a sea made of boiling hot mercury. The city holds the largest library in the world, the Archive of History, a library that holds every book ever made.

Nimbus Vale: The Industrial Capital of Babylon. Doesn't use cloud magic to fly, instead uses a large steam airship to lift the city into the sky. Exports over 100,000 tons of civilian goods to every other Babylonian City, and 25,000 tons of armaments for Liberators. Located in the Tropics of Shu, where the warm air lifts the airship(and by extension the city) higher.

Cirrus City: Known as the City of Adventure, the Extraction Center, and Heart of the Economy. Located much closer to the ground than it's sister cities, due to being the only point of access between the resources of the ruins of the surface. Hosts the Liberator's Guild, which is basically the military force of Neu Imperio. They also do reconnaissance and extraction missions down on the ground, bringing back materials from Dark-concentrated areas. They also host the Merchant's Guild, who aims to get the economy up and running to the levels of the Gran Imperio's Golden Age.
