This is all in the past, a story being told by Ozpin to the students of beacon, that's all. Also obviously this isn't how Ozpin told the story, there will be much more detail in here.

Duh

THIS IS A REWRITE

There was a village, which was home to two magical brothers. One was the guardian of Positivity, the other the guardian of Negativity. Both were important to the cycle of harmony, and both had a symbol of power. A golden apple, to symbolize positivity, and a black apple to symbolize negativity. They were dream, and nightmare. Dream was loved by everyone, everyone wanted a piece of that positivity. Nightmare however, was not liked very much, the village people believed he was the source of all the bad things that happened. That he gave you nightmares, or made you feel bad. But In reality nightmare would never yell at Anyone even if they said mean things to him, he was quiet, loving and cute. But he was also harmless, and that's what gave them the idea, that's when it started. Nightmare wasent very strong, and that was the point, he was beaten bullied and cast out by society. The bully's would often tell him things like

"No one wants you here"

" why can't you just die"

"We would be happier if you would die"

"Your a mistake"

And he was beaten, every, single, day, with each day being worse then the lasts. When he returned home he would always want to tell Dream, but he was a never home, always out with his friends and never there for nightmare. Nightmare felt, lost, confused, why wasn't dream there to help him? Weren't they meant to stick together forever? Isn't that what being brothers is all about? One day when Dream was actually there, nightmare asked him a question.

Nightmare: Dream, would you like to watch a movie tonight?

Dream turned to face his brother, a bright smile on his face.

Dream: sure!

Nightmare raised his head and smiled.

Nightmare: promise?

Dream: Promise!

But, that night, dream never showed. Nightmare stayed up through the night waiting, his brother wouldn't forget there promise, right? He began to cry, did he brother truly hate him so much?

Nightmare began to grow bitter and jealous of his brother, he wanted friends and to be not beaten up! Why did dream get to have friends when he did not? What was so special about his brother? But that's when it hit nightmare, the apple, the symbol of positivity. If he were to eat it, would people like him more? Nightmare approached the tree of life, grabbing hold of one of the apples. But as he touched it, it began to rot from all of nightmares negativity. Dream and his friend saw this and began to approach nightmare who in a panic ate the rotten apple.

nightmare: AAAAAAH!

Skin and bone were ripped apart as four long black tentacles came from his back, and black goop of hate poured all around his body. Nightmare was forever changed on that day, going from a harmless boy, to a merciless killer.

And that my friends, is the tale of two brothers
