(PHB) Dwarves are often highly religious, and still retain the clan structure that they have maintained for millennia. They are well-represented in the hierarchy of the Church of Moradin, and also tend to control local trade and craft guilds. Elves are dwindling, but those who are left in the world tend to be quite powerful. There are few elvish children, and among other peoples it is whispered that they are slowly departing this world, their work in fighting evil done. Halflings are flourishing in the Final Empire, and are well-represented among travelers and farmers both. They are so common that most places have furnishings for small and medium-sized folk as a matter of course. Humans are numerous, and many positions of authority in the Final Empire’s bureaucracy fall to humans. Dragonborn are broadly divided between the tribes that are reclaiming and colonizing lands at the fringes of the Empire and those who are wholeheartedly committed to the Empire’s expansion and security. Gnomes are widespread, and are the primary drivers behind the advancements and inventions of the past 50 years. Without war to siphon away resources (and lives), they have developed better gunpowder, airships, and other inventions that strengthen the Empire. Half-Elves are relatively rare, but those that exist need do little to become celebrities, and many of them are surrounded by a swirl of gossip and admirers. Half-Orcs are not numerous but they are commonplace, ever since mixed marriages were made legal in the Final Empire. In fact, Rehabilitated orcs are encouraged to marry humans. Tieflings, while rare, have done much to ameliorate their negative reputation, and those who are active in the Final Empire tend to be the most upright of citizens.
(DMG 282) Aarakocra are rare but are often integrated into society. Bullywugs have fled into deep swamps and are not considered fully sentient. The drow disappeared when the Dark Lord fell, except for those who were captured in the Last Battle, and elves petition for them to stay in the Camps. Gnolls have proven hard to socialize, and most remain in the Camps. Some experiments have occurred with gnoll reservations in undeveloped territories. Goblins have become eager sycophants, and are often hired to help run the Camps from the inside: “Fitter, happier, more productive!” Pockets of hobgoblin resistance still persist in uninhabited corners of the world, but peace negotiations are underway. Bugbears are trying to go the goblin route, but they are too scary to pull it off as effectively. Grimlocks also fled underground, and are thought to be used as shock troops by the drow. Kenku are slowly being released from the Camps, and often turn to stand-up comedy or theater, and kenku improv troupes are in high demand. Kobolds have glomed on to the goblin method, and are even more sycophantic if anything. They are maintenance workers in the Camps and in many cities. Kuo-toa scattered and founded a number of sea-cults, but most have been eliminated, and they have fled to the deep. Lizardfolk are highly represented among seafarers and divers once they are released from the Camps. Orcs are rare, as they tend to be resistant to rehabilitation, but the Camps are full of them. Skeletons and zombies are rare but sometimes still encountered, especially underground when they have been lying dormant for decades. Spellcasters can of course still create them, but it is a crime to do so. Troglodytes are relatively easy to rehabilitate, but they’re also rare and very stinky, and most towns have subtle laws that prevent them from living there.
(Volo’s Guide) Aasimar are rare but are slowly increasing in number as cross-planar contact becomes more common with celestial beings. They are held in high respect in the Final Empire. Firbolg have been slowly expanding into abandoned wild elf territory. They are sometimes called upon to use their abilities to hunt down magical artifacts. Goliath are often allied with the dwarves and rock gnomes, and frequently serve as heavy laborers and bodyguards. Tabaxi (are a species I just don’t like, rules-wise, and we’d have to rework it a bit if someone wants to play one) Tritons are thought to be fighting an extended battle against sahuagin and kuo-toa guerillas, but the Final Empire has not incorporated the ocean floor. Yuan-ti Purebloods are very rare outside of Rehabilitation Camps. They have a reputation for being manipulative that is well-earned, and are almost always seen as too large a security risk and are moved to Quarantine in some cases.
