Magic

Magic, there are our main types of wizards that study magic. These four are the classic, fire, water, earth, and wind. wizards can choose one type with the option of a sub element (Ex. major fire, minor earth) or they can just focus on one main type of element (so its like collage where you have a major and you can have a minor but it takes time out of your studies of the major element thus making you not as strong as a wizard without a minor) but these minor or sub groups of elements have less power or strength but they allow one to have many more abilities thus being able to counter or surprise enemies with these abilities. Now if a wizard becomes a master of their element (ex. master fire wizard) then they can turn themselves into something like a "minor" demon type of thing, basically they can turn into a demon with less power but all the abilities (in time just like anything else it takes practice) a wizard can become about half as strong as a real demon can be, which is still very powerful.Now each demon has a form that they take with each demon having a special identification sort of thing, for example one fire demon which raged through the world about 125 years before the story takes place has a deep scar that constantly looks like its bleeding, but its not actually bleeding its just a scar that the flames hit and flare out, this demon left half of the land in the north burned and scared for 50 years and that part could not be used for farming for 90 years. These types that the different demons can be: fire demons,  water serpent, earth golum, and wind sprite. Each element isn't just that element, for example ground can also control medal, wood, etc.(most earth wizards have past times of being a blacksmith) another example is wind it controls rain, lightning, fog, etc. Wizards can do much more then just their abilities or powers but they can combine their powers into one, making it stronger and much more effective ageist  others. An few examples of this are fire and ground can make lava, or a flaming meteors, another one is a whirlpool which is wind and water.Now onto the fire breather who is nether wizard nor demon but something more powerful yet understanding. The fire breather is infused with "magic fire" or the tattoos he has, and depending on the size and detail (as long as he does not become a fire demon) then he can become just as powerful with a some training and hard work as a master fire wizard and with time experience and more training he can become as if not more powerful then a fire demon.
