Each race is a living personification of humanity. The Fallen personify the Feudal Age leadership style, using Lords, Kings, and contesting Houses. While they aren't with each other, they aren't against each other either. They also have a strong honor code, as seen with the Dregs. The Hive are ritualistic Shamans and Witch Doctors. They personify the use of Voodoo, Necromancy, and Sorcery. The Cabal personify the Roman Age, and the Cesarian era. They maintain the belief of the "perfect soldier" and the belief that the leader must be the strongest of the soldiers (as seen with the Colossi and Ta'aurc). The Vex are a double-personification of the "mythological" outlook of the future, where robots are basically all-ruling. The age-old "robot rebellion" like Terminator.
