Shifters - Shifter blood runs thinly throughout rural communities in some parts of the world. Occasionally a child is born who displays some of these shifter traits. Usually, unless someone intervenes (often the Church) he or she can live a normal life. These shifters are drawn to solitary lives as shepherds or fishermen.
Gnome - As Tieflings influence finances, Gnomes influence Academics. Gnomes are sought after by the wealthy as tutors of utmost quality. The University has several tenured Gnomes, and Gnomes are scattered the world over in schools and research houses. Gnomes have a singular interest in knowledge, and the power that comes with it. Extensive study of archaeology and history has allowed the Gnomes to corner the market on ancient magics, and to introduce some technological marvels as original creations. Gnomes are almost always independently wealthy, and live in large (for them) estates with many generations sharing a compound.
Deva - Although quite rare, Deva do exist in connection with Divine events. Often a Deva will claim to be the Avatar of their God and create a highly devote cult of personality that follows them without question. Whether these actions are sanctioned or not is unknown, but Deva have garnered a reputation as Cult leaders and mystics.
Goliath - These stubborn individualists are perhaps most well known for their rebellion. Goliaths make their home in the high mountain passes, and every generation or so their extreme distance from civilization emboldens them to declare independence. After a hastily gathered army of city guards and wardens is gathered and dispatched, the Goliaths usually back down and see reason. Once in awhile a rebellious young Goliath will leave his home to make his name in the city. These Goliath are highly prized in combat arenas and mercenary troupes, and rarely return home.
Half-Orc - Called Orcs, these brutes are ubiquitous in the more dense urban areas. Their strength makes them ideal for some of the jobs Halflings can't do, and their prolific nature means they breed like rabbits. Bouncers, bodyguards, builders, and other non-skilled professionals in the inner city are often Orcs. Occasionally one will learn a trade and rise to become a genuine artisan, but stigma against buying from a non-Human will always keep them second best in this regard.
Gnoll - Some segments of the world do not regard Gnolls as thinking beings and deserving of the rights that such beings have. As a result, Gnolls are secretive and self serving. Most Gnolls adopt nocturnal behavior to further limit their contact with the public, and crime is common among them. When Dwarves are accused of theft, it is usually a Gnoll that is truly guilty.
Warforged - Occasionally recovered in old ruins, Warforged are without exception very, very old. They are considered property of the state, and kept apart from society in general. From time to time, when a show of force is needed, a squad of willing Warforged will be deployed, and they generally do their job without needing to lift a finger. For most, however, their needs are met, and they are free to spend their days in whatever leisure activity they desire. As a result, there are quite a few very powerful magicians, historians, and physicians among their ranks.
Changeling - Official word is that they do not exist. The truth is that a small population of Changelings does exist. For all of recorded history a clan of Changelings has followed the powerful, shadowing and influencing them subtly. Their goals are unknown, as is their true number.
Drow - The only colony of Drow is under the mountains. Most of their efforts are bent towards excavating and attempting to find their Underdark. While the rest of the world view it as a religious or racial obsession, the Drow are convinced that somewhere under the world lies a second world, and their home is there. While they are nominally citizens, most officials don't bother with them, as they can be extremely deadly on their home turf.
Kobold - Kobolds are commonly considered to be to Dragonborn what Halflings are to Humans. Lesser in number than Halflings, they have also avoided the traps of slavery and poverty.
Goblin - These cunning beasties are found in civilization's garbage piles. Subsisting on scraps and hand me downs, Goblins, like rats, have carved out their niche in the sewers of mankind. Commonly viewed as pests, most civilized people have no desire to associate with Goblins.
Minotaur, Shadar-kai, Revenant, Kalashtar, Genasi - Unknown in the world, if you want to play this race you are from another world, and need DM permission. That goes for MM races, too.
