Humans are based out of Western Europe.
Spain is ruled by King Ferdinand VII and it has many colonies in the Caribbean and a few other places in South and North America. Spain is under constant threat from England, ruled by Queen Victoria, which has also a large amount of colonies, including many in Africa. France currently has a Republic, though many consider that this democrazy and their utopic ideals are in their last days. The United States is an up and coming country with a lot of potential but is mostly in conflict with itself in order to maintain their own democracy. The US of this campaign extends from New England to Lousiana, with trading posts and settlements in several other parts of North America.
Humans are exactly as in the SRD rules.
