This is an alternative reality. The planets has been shrunk down into countries that are seperated by desert that has poisonous gas in the air. Each solar system is a continent. Nothing has been to space. Earth has a mixture of technology and a small amount of magic. Not everybody can do magic.
All of the different countries main creature have one feature that they share. On earth everybody has wings. They cannot fly until they moult, which normally dosn't happen till they are 13 years old. Even then they have to be taught by somebody else or themselves. Also their wings are like birds and can fold back to be barely visable onto their backs.
They are split by special wing analists when they are young into catagorys of how fast they can fly. They have to look at the bones in the wings and what the size the wingspan will grow to be. This helps get them into the right schools, where they learn to fly better as well as, strangely how to fight.
2,000 years previously, one of the few people who could do magic saw into the future. They didn't say exactly what they saw, but they did say that, the ones with 2 different colours on their wings would have great power and responsibility.
I don't own voltron or any of the characters in this.
