Some more background of the world that we'll be in.
Oerth seems very similar to our Earth at first glance - there are cars, portable communication devices, long-distance flying ships, and, frankly, most of the things you'd expect to see in our world. What it also has are magic and magical races.
Centuries ago, this was a stereotypical fantasy world, with monsters and heroes fighting constantly; hamlets, walled towns, and castles; a fierce, non-ending struggle between humans and... well, everyone else, although not always at once. Magic and metal were the tools of offense and defense; other races were captured and enslaved, or killed and disposed of. Technology and magic were fierce foes, with magic generally being the upper hand, as it only relied on the caster's own energy and force of will to accomplish things, while technology required so very much more.
Then, nearly 200 years ago, something happened. An industrious young man discovered that magic and technology didn't need to work separately. Learning how to build technological devices as a student in the artificer's guild, while hiding the fact that he was actually able to cast magic as well, he started some very secretly attempted experiments, trying to use magic and technology together, working to achieve the same end task, instead of fighting against each other. And he succeeded.
When these creations, neither magic nor technology, but a blend of both, were discovered, both the magicians and the artificers were horrified. He was forced to flee from his home, and take up a deal with the nearby King - a deal that essentially made him a slave to the throne, but let him continue his experiments unopposed. By the time he died an early death, 20 years later, his developments had changed the way the world worked. While the old-school magicians and classic artificers resisted and rejected this new way, they were vastly outnumbered by the common folk who could see the benefits from some of his creations.
Over the next few generations, the world changed due to his work. Wars stopped happening so frequently, as there were new ways to get resources that didn't involve capturing and plundering one's foes. Peace broke out for the first time in millennia, and the differing races started trying to work with humans (and each other), instead of fighting against them. Nonhuman races were allowed to walk into human lands without being captured, killed, or enslaved; trade between the races' governments started to provide new angles and new ideas in the blossoming Magitech.
Today, there's a general, but not always perfect, peace between the races. Human lands - which include cities that now look more like our world's cities, with typical city centers, highways, suburbs, and all the rest - now allow other races to mingle, live in human lands (which are becoming less and less "human" lands over the years, and becoming more of a mixed melting pot), and grow. There's only three demands to nonhuman races - first, they must not attack or harm others. Second, they must generally obey the laws. Third, they must look more-or-less human - walking (or sliding) around with nonhuman features like centaurs, nagas, satyrs, sphinx, and so on are frowned upon - it's considered terribly rude to not look "normal" when there are magical ways to shift one's appearance and more closely match the "socially-approved" style. Two arms, two legs, and one head - anything more than that was scandalous. Nonhuman tails, ears, wings, and horns, on the other hand, are considered fashionable, and it's not uncommon to see humans walking about with fake ear jewelery or other fashionable accessories along that line.
While there are still battles, still some heroes and villains in the world, some monsters that cherish the idea of eating humans and humans that just want to kill monsters, the world is more settled now than it ever has been. Race is starting to be less important than friendliness, consideration, and skill - being able to get along, do your job, and not eat your coworker for lunch. There's even signs of cross-breeding - which has happened for millennia, but previously, halfbreeds were viewed as monsters, and shunned by everyone - and the half-breed children becoming accepted almost as much as their pure-breed counterparts.
Perhaps humanity and the other races will disappear one day, replaced by their mixed-breed children and grandchildren. But that's a story for another day.
