Alpha: The strongest of the world, the top warriors, strategic war lords, and destined kings. The most agile, strong, or fast, they climb the ranks with ease.
Beta: They are the middle class. The artisans, cooks, writers, and farmers. They are astute businessmen and can be very rich.
Omega: The lowest class yet the most favored. Omegas are able to be impregnated whether they are male or female and their offspring are much stronger than between any other pairing. They are relatively rare and very sought after.
Heat/Rut: An occurrence that happens monthly for omegas and every so often for Alphas. Betas do not go through this unless enticed by strong pheromones of omegas. Heat can make omegas crave sex, a rut is something much more violent where the Alpha reverts to his instinctual need for dominance in bed.
Lay of the Land
There are three major families in Rayearth:
Phyre: The royal family and rulers of Rayearth. They represent the Sky, meaning they rule everything below it both day and night.
Ires: The Warrior family who protects the empire. They represent the Sun. Giving them jurisdiction over the day aspects of the empire.
Ankerman: The Hunter family who protects the empire against the supernatural entities that still follow their one true master. They represent the Moon.
And the fallen house:
Kastros: The ancient evil who once tried to take over the land and swallow the sky. He represents the Eclipse and his kin have all disowned him and abandoned his family name.
Artifacts: Extensions of the wielders that they chose.
Dragon Gem: The artifact that has the power to rule the universe. The last remnant of Seira: The Beginning, the End, and creator of life. Only Seria can wield it as it is her own soul.
God Slayer: The artifact that took down Seria when she ended her life. It's true form is a great sword.
Phoenix Glave: The artifact that helped Seria remake the earth. It's true form is a spear.
Eclipse Bow: The artifact that once served Seria. It acts as a bow, but it's true form has been lost to the ages.
