The World of Greyhawk
Most of my campaigns (at least those that use the Dungeons & Dragons rules) are set in the World of Greyhawk fantasy setting. The campaign setting has undergone quite a few changes over the years but I still refer to the orignal boxed set published in 1983 as my primary source.
While the game supplements refer to it as the World of Greyhawk, it would be more accurate to refer to the world as Oerth. My campaigns all occur in the eastern portion of the continent of Oerik that is generally referred to as the Flanaess, after the indigenous Flan people that first lived in the region.
The People of Oerth
Oerth is home to four major ethic groups of humans plus numerous types of elves, dwarves, halflings, gnomes and other various humanoids. While the physical differences between these groups are generally noticable, racism is relatively rare and people are judged by their actions and reputation in most civilized areas.
Members of the Flan branch of humanity have a bronze-colored complexion. This varies from a lighter, almost copper shade to a very dark tone which is deepest brown. Eye color is commonly dark brown, black, or (rarely) amber. Their wavy or curly hair is usually black or a dark brown. The ancient Flannae once wore little more than brightly colored body paints, with yellow and vermilion hues being the favorites. While many still use body paint, most of those in more civilized areas dress in whatever is common in their region (while still showing a preference for solid primary colors and very bright hues).
The Oeridians have skin tones ranging from tan to olive. They have hair that runs the gamut from honey blonde to black but brown and reddish brown are most common. Eye color is likewise highly variable, although brown and gray are frequently seen. Oeridians tend to favor checks and plaids in their garments. Clothing tends toward tight-legged trousers, close-fitting upper garments, and capes or cloaks.
The Suel folk lost their homeland long ago and since then they have been a scattered people, mixing frequently with the other groups. Those few who remain purely Suel have very pale skin, almost albino. Their eyes vary from pale blue or violet through deep purple and their hair (which is often curly or kinky) is light red, yellow, blond, or platinum blonde. Suel folk have long used solid colors for clothes. Aristocratic houses often use two or more such colors. Those of all social statuses tend to favor displaying emblems or tokens on their garments, typically of contrasting colors to the basic one. Traditional garments include loose pantaloons topped by a baggy blouse but modern Suloise folk adopt whatever is practical for their region.
The Baklunish people have golden-hued skin tones. Their eye color is commonly gray-green or green with gray uncommon and hazel rare. Hair color ranges from blue-black to dark brown. Regarding clothing, Baklunish people are of two sorts. The northern branch favors bright patterns and gaudy colors; they wear gowns and robes, or else short breeks and flowing coats. The poorer folk even wear gaudy prints, although their garments are typically a one-piece coverall with whatever additional garb they can add. The southern branch likes parti-colors of a more pastel hue; their dress is complex and full of many puffs and slashes when adorned for special events.
The Gods of Oerth
While it would take far too much space to list all the gods worshiped on Oerth, what follows is a listing of the more well-known and powerful gods.
Beory the Oerth Mother, goddess of nature and rain, is the matriach and most prominent member of the Flannae pantheon. Her daughter Berei, goddess of homes, agriculture and family is often venerated. Flannae warriors give praise to Pelor the god of sun, light, strength and healing. More scholarly Flannae praise Rao, god of peace, reason and serenity. All fear Nerull the Reaper, god of death, darkness and the underworld. While few worship him, it's worth noting that the evil demi-god Iuz is a part of the Flannae pantheon.
The Oeridian people worship Zilchus, the god of power, prestige, influence, money and business. Not surprisingly, they often give praise to Procan, god of the oceans and sea travel, to have him bless their merchant fleets. They have a god for each direction of the wind; Atroa is the goddess of spring and the east wind, Sotillion is the goddess of summer and the south wind, Wenta is the goddess of autumn and the west wind, and Telchur is the god of winter and the north wind. All four of these are the children of Velnius, god of the sky and weather. Other prominent members of the pantheon include the feuding brothers Hextor (war, discord and massacre) and Heironeous (honor, valor and justice) as well as the twin gods Celestian (stars, space and wanderers) and Fharlanghn (horizons, distance and travel).
