In the world of Iris, there only three races; The Titans, The Elves, and The Humans.
The elves were made directly by Apollon and therefore will always be on the side of the light, or be neutral. Elves have the longest lifespan of all three races. Elvescan choose to either be Healers or Sorcerors.
The titans were once nearly invulnerable because they were directly linked to Eres's magic. Now, they have only retained their powerful body. Titans are only Neutral or Dark.
Humans are the most diverse out of all of the races, as they can choose from three classes, be on any side, look erraticly different than others of his or her species, and wear a much larger array of clothes.
