In the beginning, four sisters lived in Space World, where nothing had been created yet. 

Their names were Earth, Water, Fire, and Air. 

They never got along with each other because they were all so different.

Earth was more grounded than the others. She was also more practical, dependable, stable, and unwavering unlike her sisters. However, she was also very worrisome.

Fire was the most impatient of the four sisters. She was also more impulsive, more aggressive, and more temperamental. But sometimes, when she was feeling nicer than normal, she was passionate and idealistic.

Water was always the most sensitive and emotional sister. But when she wasn't upset, she was calm, empathetic, reserved, and intuitive. Unlike her sister, Earth, she was very unreliable.

Air was the youngest of the four sisters. She was the most intelligent, sociable, communicative, free spirited, unpredictable, and analytical. But unlike the other sisters, she was definitely the most indecisive. 

One day, they came across a planet during an argument. Somehow, someway, the four sisters actually agreed to have a competition to see who's element would do the best on this mysterious planet.

They ended up creating a lot of different things. Without any of these things, we would never be where we are.
