Caste System based on Circle laws:
The Circle: This is obviously the highest of the high, the Circle practically dictates everything from who gets shifted to this caste to the registration of every newborn baby whether he or she be legitimate or a bastard. Obviously, since the Circle is the law, only those children under each Circle member can replace their predecessors, unless otherwise specified by said member. However the replacement line has to be part of the Aristocracy, and only under the circumstance that the apointee cannot sire a son.
Aristocracy: The Aristocracy is divided into four houses each based on a certain mother element. Each of these houses have different sets of tradition, emblems, clothing, even architecture. Since the Circle is also comprised of at least one representative of each house, the basic Kod Mezu culture has become an integration of the different ways of life of the Aristocracy.
Aquiler- Water: Probably the most political and influential house, the Noble House of Aquiler bases their power on the element of water. They prefer to carry around long staves and are better equipped for very long range. They also specialize in persuasion and social skills, and is the premiere house for the study of conjuration. Most of their culture revolves around their belief that conflict is best when the enemy cannot touch you. They also pride themselves among other houses, believing to be the purest of blood. That being said, majority of the Circle members are of this house, and it will be a long time before anyone would dare question their authority.
Solaris- Fire: The Unstoppable House of Solaris relies on the power of fire to fuel their drive for power. Unlike the Aquiler who use their staves as a symbol of their authority, members of house Solaris prefer the use of wands equipped for medium to short range. Since as far as anyone can remember, both house Aquiler and house Solaris have been at each other's necks, having elements that oppose one another. While Aquiler prides itself on its nobility, the members of house Solaris are known for their ingenuity and passion. They specialize in weaving unique spells and combining them to make powerful combinations and techniques.
Ventra- Air: Like their mother element, The Ever-Shifting House of Ventra is almost unnoticed among the ranks of the Aristocracy. Believing themselves to be the fastest, these Kodans are skilled in unarmed spellcasting, claiming that wands and staves only slow them down. They never travel in groups, and if they do, the most of them you'll see together are only in groups of two, no more than three. Strangest of all the houses, they even have their own sign language, known only to the respective members of the house. They prefer teleporting short distances to weave around the battlefield, causing enemies to often miss or hit each other in the process. Members of House Ventra usually don't engage in politics, but rather rumored to be most in contact with the lower castes, and the underground. If ever there was a Mafia for the Kod Mezu, this would be it.
Tyrrhane- Earth: Believed to be the lowest of the Aristocracy, The Immovable House of Tyrrhane are composed of monks and priests. They run the religious aspects of the people, owning all the Churches throughout Kod Mezu territory. They carry around, believe it or not, beads and bags of incense to cast their spells, often causing roots to tangle their foes or creating holes to trap their enemy. While most of the other houses focus on offensive magic, Tyrrhane acolytes prefer strengthening their minds to accomplish what no other house can do: Group Synchronization. While in groups, their spells deal more damage or defend better and in a bigger area of effect. While they have quite the array of destructive magic, their true specialty lies in protection. Few can ever really harm an acolyte, and they have the deepest mana pools of all the other houses.
Scholar: Better known among the Kod Mezu as the Universalists, the Scholar caste is comprised of different members of the Aristocracy who have dedicated their time for research and study. The Universalists have built their own College, where most of the Aristocracy's children now enroll in. Being teachers and scientists, the Scholars have waned in magical prowess, but that does not necessarily mean they are useless in a fight. If and when need arises, they can rely on spellbooks to combine different elements of the four houses, at the cost of a lower mana pool. Since they rely on books now, they cast their spells longer at the trade-off for better power and potency when casting from their deep knowledge of combined elements.
Shadow: Also called the Black caste, these dregs of society are composed of bastard sons and daughters and the Houseless, seeking instead the pleasures of guilty living. They reside on the outskirts of the city, and have since honed their magic to be more for stealth and thievery. These are the mercenaries, the assassins, and the undesirables of the Kod Mezu community. Don't let their reputation fool you though, as even the highest member of the Aristocracy sometimes approach them for their special services, like guard duty or "caretaking". They still have a bit of magic in them, but without proper training and knowledge, they are stuck with only using the simplest of spells. Over time, their bone structures have changed, responding to their need of a different lifestyle than the others of their kind. Younger generations have more muscle mass and bone density, allowing them to wield some of the heavier weapons available. Some of them are even hybrids, oftentimes half-Kodan and half-Ehrui.
