The people and their civilizations

The people that are scattered around the world are wide and varied. ranging from the elves of the far west to the humans in the north.
The kingdoms are wide-reaching but cities are few and far between. due to the harsh environment of the world around them, cities have built themselves into strongholds and made them heavily resistant to the elements around them. walls consisting of stone and brass heating or cooling pipes that are attached to a centralized magical furnace. while the elves live in comfort and luxury they have one central city that has stretched out wide across the land.
how ever a lot of humans wanted to expand their individuality so there are 15 to 16 cities that have scattered from the dessert of glass. to the snowy tundra of Ice blight. while humans evolved technologically to make up for their innate lack of magical capabilities. they quickly deviated into a complicated mess of lords and lady rule. focusing on different fields the mass collection of human knowledge quickly grew.
The elves were not to be left behind in that regard, however. pushing forwards in enhancing their magical abilities they created more and more powerful magic, however, they are extremely secretive about what their advancement was. tending to be wholistic in nature they work quickly together. defensive and creative the only way to have a good time with an elf is through food and drink. but they are all trained from birth to keep their city secrets.
but dwarf, gnomes, and halflings have banded together to populate the sea in floating cities that are detached from bigger civilizations. mostly fishing drinking and inventing the cities of these races are more focused on themselves. businessmen and women at heart tend to be relaxed in nature. and mostly open to outsiders.
The orcs have found themselves in the pirating life. tribes became ships. and often only attack other pirates. or unmarked ships. they are aggressively into their drink and meat. and according to some human settlements, they are passionate individuals. but tough in groups
The Tieflings are nomadic people setting off and searching in their own regards the work hard to insure they live long enough to be useful members of whatever settle meant they may stumble into. but don't rely on them too long as just as quickly they arrived they would typically leave soon after.
The dragon borns tend to live in the world scar. allows them to create small encampments and manufacture strongholds near the world scar as they are a bit more resistant to the random burst of magical elements 
"The people who populate our planet are wide and as complicated as the planet itself. often times I wonder how many more people are simply hiding out there." - Philosopher Jessary
