Changeling: Changelings (Doppelgangers) are very rare, but they can fit in with any society. If you want to play a Changeling, you need to speak to the DM first.
Deva: Deva are not born per se, but appear fully grown knowing how to speak (multiple languages) but do not remember any of their past life. Still, they need to be educated. A Deva might have appeared in a sacred site nearby and been discovered by cenobites from the Abbey, and taken back to study with the other characters.
Dragonborn: One part of Lord William’s cohort was a company of members from The Order of the Dragon, a group of holy warriors dedicated to Bahamut. Many of these members were Dragonborn. Some of these became landholders especially in the eastern part of Drakesbury. There are a few Dragonborn that serve the town guard, but more still that serve in the Ducal Guard.
Drow: The Dark Elves are a very rare sight in any of the civilized lands, since most of them are evil Denizens of the Underdark. However, there is a small colony of the Nightborn living in the forest to the north of Drakesbury, so they are not totally unknown. They are still looked on with intense suspicion by most commonfolk. A Drow PC could be one of these Nightborn come to town.
Dwarf: Dwarves make a sizable minority of the population of Drakesbury, particularly in the suburb of Holywell. The dwarven delving of Hammerfast in the Mithral mountains to the north is a major trading partner with Drakesbury.
Eladrin: Eladrin are somewhat uncommon in Drakesbury, but a few of the manors in the surrounding rural area are owned by Eladrin families. Alternatively, a PC could be a child of emissaries from the Eladrin city of Gorias, which appears from the Feywild on moonlit nights on an island in the middle of Lake Evendim, the source of the River Dwimmer.
Elf: Elves are more numerous than Eladrin in the area, although they might live outside the town itself. The Duke employs elves as guardsmen, gamekeepers, scouts and foresters.
Genasi: One of the large trading houses in Drakesbury is owned by the Genasi family of Elazan, which owns a large compound near the east gate of the city and dock and warehouse in Holywell. They have connections with the Genasi city of Mote Alizrash.
Goliath: Goliaths are rare in Drakesbury itself, but there are a few clans that live in the Highlands to the east of the town. Some have moved into town, mostly employed as porters in the docks area or as a town guard. A PC might be a child of one of these persons.
Half-elf: A few half-elf families live in and around Drakesbury. They tend to be landowners or expert artisan-craftsmen.
Halfling: Halflings are a river folk and a number of them live along the River Dwimmer in small villages. There are a number of Halfling families also living in and around Drakesbury, particularly along the Abbey Foregate.
Half-orc: Half-orcs are either the product of two half-orcs mating, or a human and an orc mating. There are a very few half-orc families that live at the edges of Drakesbury and a half-orc character could be from one of those families. Alternatively, a half-orc could be the child of a human single mother who lives in Drakesbury.
Human: Humans are of course the most populous race in Drakesbury, and can come from any walk of life.
Shifter: Like Goliaths, Shifters tend to stay away from populated areas, but a few families live in the area, mostly employed as trackers and hunters.
Tiefling: Tieflings in the Hundred Kingdoms tend to live a nomadic life, similar to gypsies or Travellers, but instead of entertainers, they tend to be peddlers. The more successful (and older) Tiefling traders though, form their own merchant houses in a town or city, and let their younger relatives drive the wagons. One such patriarch, Damakos Aezar has formed his own trading house in Drakesbury with a house and shop on the Foregate. A PC might be an Aezar cousin.
