Something to note is that there are two big categories that people group the races of the world in.
The Divine Races are those who traditionally sided with the Gods during the Divine War. They tend to be the most accepted within mortal society. Most of the 'traditional fantasy races' belong to this category.
The Redeemed Titanspawn are those races who traditionally sided with the Titans during the Divine War or who have significant ties to the Titans- such as the Blood Sirens that are all born in the Blood Sea and carry the taint of Kadum within their veins- but have overwhelmingly defected in the aftermath of the Divine War. These races, while accepted in most places, tend to be viewed with some degree of suspicion in nations hardest hit by the ravages of the Titans.
There are other races that defy such neat categorization. Some are nearly unknown to the majority of Scarn, while others are widely known and carry their own stereotypes.
Divine Races
Humans- Humans are at once the most varied and most homogenous of the Divine Races. No God or Titan claims their creation, but ancient myths speak of them walking forth from the mountains of Albadia in the early days of Scarn.
High Elves- Regal and sophisticated elves who have regained their effective immortality following the resurrection of Jandaevos, their former god. Culture, the arcane arts, and bowmanship are some of their race's most cherished past-times.
Ganjus Elves- Athletic elves of dark complexion who live in sprawling tree cities in the jungles of Termana and have a deep connection to the natural world. It is said that Denev the Earthmother once blessed their race in the ages before the Divine War.
Drendari Elves- Dark of skin, white of hair, and skilled in the magical arts, the once-proud Drendali elves live deep beneath the ground in the crawling city of Dier Drendal. They hold a bitter hatred of the dwarves of Burok Torn, claiming that their former allies abandoned them to die.
Forsaken Elves- Although the return of Jandaevos allowed the Forsaken Elves to return to their former selves, some remained opposed to it and choose to live shorter, more fulfilling lives. Many scoff at notions like morality and choose to live a life of hedonistic self-indulgence.
Broadreach Elves- The Broadreach Elves primarily inhabit the corrupted lands of the Hornsaw Forest and are a dour and harsh people due to living in a region where everything seems out to kill them. They mark themselves with mystic tattoos that they use to represent major life events.
Wrack Elves- Cousins to the Ganjus Elves, the Wrack Elves lived in the once-verdant lands of the Asherak Desert. They felt the land's pain as verdant woods turned into sand and dust and became a grim, bitter people that wander in search of a way to heal their land.
Shining Elves- The Shining Elves are a blight on the Scarred Lands and were created when followers of the elven traitor Ta Maios- who made pacts with demons and opened a portal to a dark outer plane to join it with Scarn so that he could be reborn as a demon king- mingled with demons and bore their children. Born of elves and demons, these elves are as beautiful as they are cruel.
Half-Elves- The half-elves are a people followed by a dark reputation. Before the resurrection of Jandaevos, an unfortunate number of forsaken elves often tried to ceonceive children in pairings with the more populous humans- willing or not- out of a desire to save their people from extinction and the stigma follows all half-elves to this day.
Kelder Dwarves- The Kelder Dwarves live deep within the Kelder Mountains and have adapted to a life underground well. These dwarves place great emphasis on honor, craftsmanship, and family and their warriors have kept the Calastian Hegemony at bay for decades.
Charduni Dwarves- The Charduni Dwarves were created by Chardun, the God of Tyranny, and were set on Scarn to bring his harsh virtues to the world. Although their god has grown disillusioned with them, they live up to many of his ideals and are pragmatic, hardy, and orderly.
Wood Dwarves- Wood Dwarves have lived in the Hornsaw Forest since long before Mormo's flesh and blood twisted it. They live among the Broadreach Elves and cherish the virtues of hard work, asceticism, and compassion.
Halflings- Unassuming devotees of life's simple pleasures, the Halflings are overlooked by many. A slim majority of the race live within the lands of the Calastian Hegemony where halfling slaves, oddly enough, lead comfortable lives as favored servants of the nobility.
Jungle Gnomes: Jungle Gnomes primarily live in Termana and are devoutly faithful to the precepts of Denev the Earthmother. Contemplation, a love for beautiful sights and sounds, and philosophy are all held dear by the race.
Winter Gnomes- The Winter Gnomes are native to the frozen lands of Fenrilik and are seemingly formed out of pale blue ice, with hoarfrost forming their hair and beards. The strange little fey are shy, but possess keen minds and uncharacteristically warm hearts.
Ubantu- The Ubantu are a short and thin cousin race to humans and wander the Asherak Desert in nomadic tribes, taking refuge in the shells of
long-dead giant turtles during their stops in oases. They are devout followers of Hedrada and etch tattoos with venom into their flesh in order to boost their natural resistance to toxins of all kinds.
Manticora- Although a Divine Race, the leonine Manticora were once the chosen spawn of Vangal, God of the Apocalypse, and are feared by many as dangerous, something they hope to fix. They greatly value history, storytelling, self-sufficiency, and independence as a people.
Aasimar- During the Divine War, good outsiders fought alongside the mortal races and a few grew so close that they fell in love. Those who did often conceived children bearing celestial blood. These striking children grow up bearing the power of the heavens.
Tiefling- While tieflings can be born of almost any coupling and circumstance with the Divine Races and fiends, the most common are when ambitious mortals make pacts with the forces of Hell and the price for the pact is not only the individual's soul, but carrying the devil's bloodline across the ages. Regardless, tieflings grow up with the dark powers of their forbears.
Redeemed Titanspawn
Orcs- Orcs were created by Kadum the Mountainshaker were thrown at the Divine Races by the thousands in the Divine War. Despite their hulking appearance, they are not a savage species and have an open tribal lifestyle focused around honoring ancestors and divining the stars for their purpose in life.
Half-Orcs- Many Half-Orcs bear the same stigma as the Half-Elves, only slightly moreso because of their titanspawn blood. Orcs were originally created by Kadum as living engines of war and were forced by him to breed with captured foes to create more soldiers as fodder for his armies, a grim stigma that seems to taint many people's view of Half-Orcs.
Asaathi- The snake-like Asaathi are the children of Mormo the Mother of Serpents and joined the Divine Races after much deliberation in the aftermath of the Divine War. Their society is intricate- rooted in tradition and the pursuit of perfection- and filled with philosophies and politics.
Ironbred- Once known as the Sutak, the equine-featured Ironbred were the children of Thulkas, the Father of Fire and served him loyally until his defeat. The Ironbred are a people slow to trust, unswervingly loyal to their friends, and who hold a deep hatred of the Titans for their bondage.
Slitherin- The Slitherin are a race born of the rats who fed on gibbets of flesh from the Titans and grew into their own separate race. While some are still born mad from the power of their blood, most simply possess a drive to experience new things and discover themselves as individuals.
Piterin- Few know the origins of the batlike humanoids slandered as 'bat devils', but their veins run with titanspawn blood, thin though it may be. Piterins are a contradiction: clannish loners who are kleptomaniacs, blood-drinkers who also do many good deeds on the sly.
Blood Sirens- Blood Sirens are vanishingly rare, a mermaid-like race created when a blood sea parasite inhabits a female humanoid corpse and fuses it to passing sea life. The process normally results in the parasite controlling the new body and become evil to the core, but rare cases exist where the host's now-amnesiac mind remains in control and only acquires urges from the parasite. Blood Sirens are devastatingly beautiful even if their host body originally was not and can use magic to turn their fins or tentacles into legs on land.
Changeling- Hags, while not traditionally thought of as such, are titanspawn who possess powers handed down from the titaness Mormo. While many are barren and are forced to kidnap children to turn into haglings, some are horrifyingly fertile and, in grotesque and often lethal couplings with mortal men, conceive heterochromatic daughters with the power of witchcraft in their blood.
Other Races
Minotaur- The minotaur are the children of Denev the Earthmother and hold a deep respect for the natural world. A magical virus of Chern the Plaguebringer almost drove their people to extinction and what few remain do their best to preserve their people and traditions.
Gnolls- The hyena-like Gnolls are a race of nomadic savages from Termana, who wage war and take slaves as suits their whims. While there are some who turn from such a lifestyle, most still have a morbid sense of humor, a tendency towards violence, and a penchant for glutting on food. There exists a small subset that are much more peaceful who have long been allies of Termana's elven population, but most of their number were martyred during the Divine War.
Hollow Legionnaires- Many great and noble warriors were lost during the Divine War, but could not pass on to the Outer Planes. The paladin orders of the Gleaming Valley found a way to bind these lost souls to armor, although the process has the side effect of stripping them of their memories. Only those who understand the downsides of the process and are willing to accept them undergo the ritual to bind their souls to animate suits of armor.
Tatsuri- Children of humans and the dragon shoguns of the Dragon Lands, the Tatsuri are a proud people who place great importance on decorum and ancestry. They bear the blessings afforded by their draconic blood and the nature spirits who serve their forbears.
Dragon Lands Kobolds- Native to the Dragon Lands, these kobolds look down upon their primitive kin as crude imitations of their perfection. Rigid and unbending in honor and imperiously egotistical, these small descendants of dragons nonetheless value courtesy and loyalty above all.
Terali- A tribal race who resemble upright leopard people, the Terali are deeply spiritual wanderers who roam the world in search of wisdom and luxuries. They tend to worship their ancestors and those of their number born with black pelts have a high aptitude for magic.
