Full racial descriptions can be found in the rulebook.
Of all the known races dwarves are perhaps the most introvert of them all. As long as the world outside their borders stays away from them, they are uninterested in interacting with the other races. Their ambitions and goals just don't include the rest of the world.
But don't be fooled. While a dwarf prefers the chambers and halls of his own fortress he is not afraid of going into the outside world. Dwarves adapt easily to the world around them and can live just as comfortably above ground as below ground.
Elves resemble humans. From a distance it's impossible to distinguish between the two races. But a closer look will reveal certain differences. Elves have a longer and thinner body. They often reach a length above 2 meters (which is 20-30 centimeters longer than regular humans). Their ears are pointy and their eyes have a feline touch. While humans vary from light pink to black skin colour elves are always very light pink. Their hair is blonde and the general style is to keep it long and flowing free in the wind.
The Ende is divided in two groups, Ende Andii and Ende Noii, of which Ende Andii is the more numerous one.
The Ende Noii, or visitors as they also call themselves, are the dead of any race whose willpower is strong enough to fight the mighty pull from the Kingdom of Death.
The Ende Noii only consists of first generation unliving souls. Eventually the pull from the Kingdom of Death will overtake them and they will resign to their fate as dead.
Greenskins, or greyskins as they also are called, are a collective name for some races living in the caves below the earth. The name comes from the colour of their skins which may vary between different tribes but stays between dark green and various shades of grey.
The dominant race is the Orcs. Their mix of brutal strength and intelligence/cunning have allowed them to reach a higher rank in the greenskin society than the weaker but more intelligent Goblins and the incredibly strong but dumb Ogres.
Humans are the most diverse of all the races. Even though dwarves are the most adaptable to new environments, their low interest in the outside world makes them more or less alike. Humans on the other hand have a flexible mind and are both willing and able to adapt to new ideas and situations.
More than any others, the humans have a tendency to see themselves and their own way of living as the one choice.
The Krant is a strange race. Instead of the soft or leathery skin of the other races they have a chitinous exoskeleton that also supports their body. They are very diverse in shape and size, with some of the workers growing as large and strong as a fully grown horse. Most of the Krant are a lot smaller though and often only reach the abdomen of a human.
The Krant lives close to each other in underground mounds. Their natural telepathic ability enables them to develop the Krant mind as soon as there are more than a few individual Krant.
The Mevaro story is a sad one. They do not belong to this world and they know it. Although the full story is shrouded in mystery and only hinted at in the legends of ages long past it is known that they evolved and flourished in another world. The world of Elaint-Torr!
Elaint-Torr, if the legends are true, is the Mevaro paradise. The ocean world had a tropical climate and was filled with large archipelagos. The Mevaro were the dominant species and they prospered. How it comes that they left Elaint-Torr is a mystery.
