In some regions, various occupations might be exclusively staffed by members of a particular race or ethnic group. As examples, a city's butchers might tradtionally have orcish blood, or all the dwarves in an area could be expected to join the miners' guild (even if they personally have nothing to do with mining). Those who violate these stereotypes may find themselves in conflict with local customs or idiosyncratic laws.
On some of the islands off the coast, the rites of the local fertility god revolve around ceremonial death and rebirth. The religion's priests have overcome this cycle, however: Each of them is actually undead, ceremonially slain and "reborn"! Their religion is otherwise unremarkable, being an odd offshoot of the mainland's religions. The priests vow to resist their undead cravings, seeing these as the "cycle of life" attempting to reclaim their spirits.
According to the Journals of Lord Goidol, the people of the Southern Cities wear heavy coats all the year round, despite the stifling tropical heat. They claim that to do otherwise angers the gods, and it is true that visitors who refuse to don the local garb are often struck down with a paralytic fever.
There is a land where every person wears spectacles. Those without eyeglasses are considered to be the lowest stratum of society, so adventurers without glasses are treated like outcastes. It certainly would explain those heroes wearing sunglasses for no apparent reason...
In a city where the justice system features judicial dueling, plaintiffs and defendants are permitted to request a champion to take their place in the duel: Someone chosen by lot from among the foreigners in the city. When anyone first arrives, they are given an enchanted ceramic pendant that marks them as a candidate for "court duty".
Wealthy folk entering the city are often escorted by burly guards, paid to carry pendants on their behalf: They elude court duty in that way.
Adventurers may seek work as a rich man's proxy or may find themselves magically summoned to serve as a champion.
In an isolated mountainous region, the local miners build their stone huts right next to the sarcophagi of their dead. In the winding tunnels of their mines, the spirits of their ancestors toil alongside them, sensing where the best deposits will be found and guiding their picks' strokes.
The Jiangsi was the name of an undead being in Chinese folklore and mythology. Usually translated as zombie or vampire for Western palates, the Jiangsi was really neither. They appeared as simply risen, fresh corpses. They moved (peculiarly!) by hopping rather than walking, and sought out the living to suck the Qilife force from their victims.
Perhaps significantly more interesting than the Jiangsi itself, was the lore surrounding them. "Zombie wranglers", or "Corpse Herders", usually Daoist priests, were men tasked with delivering these undead beings back to their respective home towns. Tradition in China placed great importance and emphasis on the return of the dead to their homes and families, and thus the corpse herders came to be. By using magick words and talismans they would animate the dead, and by placing specially inscribed parchments of paper over the Jiangsi heads and faces, the corpse herders would be able to control the hopping corpses. Then like pied pipers, they would lead processions of subdued undead, across many miles, rhythmically chanting and ringing tiny bells.
Special inns were built across China to house these undead caravans, as the zombies could only travel by evening and night, the sun anathema to them. Rows of doors opening to barely a closet-space, lined the walls of these special establishments. Behind these doors, the corpses would be stored upright while the corpse herders rested in rooms.
The Jiangsi under the control of a corpse herder were quite harmless, merely hopping after him, silently and without complaint, for weeks and months. If however, the magicked parchment would somehow be removed from their faces, the creatures would immediately seek living humans to kill. Their thirst for Qi was unquenchable.
The job of a corpse herder was an interesting one to say the least.
