Humans are not indigenous to this world. Many arrived as traders, pirates, settlers, and invaders. And although not native to this world, they still make up the largest racial group on the planet.
The human kingdoms differ from the other races in that each human kingdom has its own culture and, in some cases, multiple languages. The reason for this is elves and dwarves nearly all come from the same background; therefore, all the dwarves of the same sub-race have the same culture and language. The same holds true for the elves and halflings as well.
Human kingdoms also have differences in opinions on how to govern themselves and each other. This leads to a vast difference in governing types as well as constant conflict between kingdoms and conflicts within the kingdoms.
The first known humans to arrive on this world were invaders. A group of religious zealots that believed this was their promised land. A belief that did not sit well with the people that were already here, like the elves and lizardmen. Battles and wars were fought people scattered, regrouped, and fought some more. More humans arrived from other locations and fought among each other, and fought the other races for control or superiority over an area. After several hundreds of years, lines were drawn, some lasting kingdoms were established and lines were crossed and kingdoms destroyed.
Currently, humans occupy a large area of the world. Having vast empires, small kingdoms, and independent city states. Battles are still fought over trade, material rights or religious and moral beliefs, but not on the extent it was in the past.
Because of the differences in culture, characters from certain areas have access to skills, feats, proficiencies, classes, and languages in one kingdom, that may not be available in another. For this reason, the choosing of a homeland is important. Off world characters do not gain access to any of these bonuses or hindrances and are created straight from the players guide.
