Establishing races now.
* Human (playable): Far and away the most common race here. Aging is a little slower on Aion, so while people still die at roughly the same age as always (<120 years), it takes them longer to show signs of it. Additionally, for reasons too complicated to explain in one sentence, the majority of humans on this world are dark-skinned asian-looking types.

* Immortal (non-playable): Distinguished by their pointed ears, Immortals are otherwise no different from ordinary humans except for their inability to die of old age. Only one is known to live on Aion, though there are rumors of a second, less-benevolent one roaming the world.

* Orc (playable): The product of some very nasty experiments on an (now-dead) Immortal, orcs are designed to maintain their peak physical capacity from adulthood to death. Aging doesn't slow them down, and their muscles never atrophy, allowing them to reach heights of strength only dreamed of by ordinary people. This means, however, that they also have increased energy consumption, and in fact one orc regularly eats enough for about two or three humans. Thus, orcs rarely have developed civilizations and are more commonly found either as nomads or mercenaries for the wealthy. If an adequate food source could be found, orcs would reproduce like rabbits and overpower everyone else. This fact is not lost on certain ambitious wizards...

Voidspawn (playable): Sentient mana-spirits that appeared from the Chasm. Since they are incapable of affecting the world without a physical form, they prey on creatures that are on the brink of death, pushing out a native soul to take its place. The resultant being, if it survives, can be identified by its purple irises, and often possesses immense magical talent. Being non-native to their bodies, however, their lives are rather fragile and can, at times, be destroyed by mundane things like stress.
