World Setting

History
The Leviathan campaign world is similar to our world, around 1785. Most of the names of places and countries are unchanged. The same general people, their conflicts, and their resolutions occurred pretty much as it did in our world.

Some of your characters may have fought in the Revolutionary War that recently ended, where Columbia (America) won it's independence from the mother country, Britannia (Britain).

Races and Nationalities
Racial friction persists, made more complex by the sheer amount of variation in D&D (though mostly when they mingle). Most races tend to to keep to themselves unless the others have something they want or need.

The most common folk are humans and halflings, most hailing originally from Britannia, though this generation is mostly native to Columbia. Elves are regarded in a similar manner to the Native Americans of our world. Half-Orcs, are regarded similarly to the Blacks of our world at that time, still largely enslaved in the "civilized" world, though slavery had recently been abolished in Massachusetts, where the campaign starts. Dwarves are typically from the highlands of Britannia (Scotland), Goliaths from Russia, Gnomes from Hibernia (Ireland). Dragonborn, Githzeri, and Tieflings come from the far east, exotic traders from the Orient. Eladrin from Marianne (France), and Hobgoblins from Germania (Germany). Other races hail from all around (if you pick one not listed here we can figure out where you originally came from).

Religion
Religions are similarly diverse, but less at odds with one another, as Columbia was formed as a place where freedom of religious expression was core to the tenets of it's founding. Bahamut is the major deity in the region, with incredibly strict adherents who uphold various nuances of his ideals; most notably the "Religious Society of Friends" (Quakers) and the Precisians (Puritans). Erathis is a strong second deity, and growing due to the rise of more industrialized civilization, with the closest analog in our society would be industry personified. The other deities from the core rules feature in the campaign, though not necessarily as prominently.

Blatant use of magic became exceedingly rare after the Witchcraft Trials (roughly a century earlier), but society still benefits from magic every day, and has become more tolerant of its users again.
