Avatar and Benders
In this guild you're a bender of one of the four elements. Water, earth, fire, and air. There will be one Avatar(master of all elements) and one future reincarnation if the current one is to die. Masters are appointed through tournament and how well they role play. This level will be determined by creativity.
The Four Nations
The world is divided into four nations. Its kind of like four different cultures.
Earth: This nation is a Monarchy controled by a king. Within this nation are several kingdoms and of the strongest is Ba Sing Se. The earth nation is of the largest in the world.
Fire: The fire nation is ruled by one person alone and thats the fire lord. The power is passed through blood.
Air: There are three air temples but they're distant from the other nations. The inhabitants are monks that live high in the mountains unreachable by foot. The three temples are North, South, and East.
Water: There are two main water tribes located in the east and west. They're sister tibes with rich coustoms and the power is also passed through blood.
The Four Elements

Now one of these elements will be your strength so choose wisely. As you can see, everything is whole. We are all equal. Be a bit creative and alter your element. Example: water>>ice.
(It also have to make sense)
