Serana's POV

So before we get into my shit storm of a life, let me take you to the beginning.

Have you ever heard of the butterfly effect? Basically its when a small event triggers a large event. Well at least thats what my math teacher said anyway.

Relax, not every little event triggers a larger and more horrible one. So rest assured that the candy wrapper you threw on the street that one time isnt going to come back and bite you in the ass.

An example of the butterfly effect would be when a group of boys in school dare there friend to go up to a girl and tell her shes ugly as a joke to get a few seconds of giggles and smirks. Maybe that girl will just pass it off as boys being boys. Some might take it personally. Maybe that girl will think about what the boy said to heart and it will start bothering her on the inside for days until she cant take it anymore...and she kills herself. A stupid joke turning into a suicide.A small event triggering a large one.

But anyways im rambling time to get back on track. Now that you understand the butterfly effect, lets go back 16 years ago. On one sunny day at Beacon academy. Team RWBY and team JNPR were sent to the forest of forever fall to clear out a pack of grimm as training...but this exercise...Will be the beggining of a horrible future.

The minor event in this story that causes a disaster is actually a tiny,normal human trait that millions of people experience every single day.

Forgetfulness

Im not going to say the consequences of what happened because ...come on that would be ruining the whole story. But i will say that one of the consequences of that day was...my birth.

*16 years earlier* (Authors pov btw)

"This forest is so beautiful." said Ruby warmly.

"Yeah, it is and the sap the trees make is sooooo yummy!" exclaimed Nora playfully.

"ugh , you can count me out on that last part. I think im allergic to that stuff." said Jaune while looking at the map for the spot professor Port said the pack of Beowolves were sighted at.

"So how many grimm do you think there would be for them to send some first years like us?" asked Jaune nervously.

"Dont worry Jaune, we will be fine. There is eight of us after all." said Pyrrha resting a reassuring hand on his shoulder.

They walked through the forest a little bit longer, enjoying the beauty of the forest as well as having small talk along the way. They stopped when they heard a low growl come from a bush near by.

"What was that?" asked Ruby. She soon found her answer when about 20 beowolves emerged from all around them and formed a circle around the two monsters were snarling and growling at them hungrily. They all got into their battle stances, prepared to fight the beasts infront of them.

"Alright guys, you know what to do, lets get em!" Said Ruby reassuringly. The rest let out a battle cry before they charged into the group of beasts staying relatively close to their partners.

Jaune and Pyrrha were blocking attacks with their shields and cleaving heads with their swords. Ren was shooting into the wave of the crowd while Nora smashed things into a pretty red was taking enemies head on distracting them while Blake sliced them while they werent looking. Weiss was using her dust to destroy the beasts with fire and ice while Ruby turned them into confetti with her gigantic scythe.

The fight was incredibly easy, only took them a few minutes to clear them out. When they were done and all the bodies were disappearing. The two teams gathered near eachother and smiled.

"You guys did great." said Pyrrha. Ruby smiled.

"You guys did pretty good too." she replied.

"We all did great." chimed in Jaune. Their talk of triumph and complements were cut short when they heard a growl from behind them.

When they turned to the piles of ashes that used to be creatures of grimm, they saw a lone beowolf, about half the size of all the other beowolfs they have killed.

"hmm,guess this one strayed from the pack and showed up to late." said Jaune. The lone grimm was looking at what used to be his pack and the eight humans infront of him.

Not all grimm were mindless,the smartest grimm remember the goal they were given since creation,their one singular purpose for existence.

Destroy all of mankind.

The lone grimm knew there was no escape, if they had taken down his whole pack, what chance does he have? He lowered himself in a stance ,ready to pounce when one of them makes a move. If it was going to die,he would take a human with him.

"Wow, killed all his buddies and it still wants to fight? Gotta respect that." said Yang sarcastically.

"You know, they say that the last grimm of a pack will bring good luck to the one that kills them." added Ren. Everyone glanced at each other.

"I want to kill it !" exclaimed Nora.

"No i want to kill it!" said Ruby puffing her cheeks and crossing her arms .

" I got a test with oobleck later...I could actually use the luck." Said Jaune quietly.

"I have a idea. Why dont we all check our aura meters on our teams scrolls and whoever has the most gets the honour of taking the kill." said Pyrrha, being the voice of reason as always. All of them glanced at each other and then back at the lone grimm still in its stance, and then back Pyrrha with a shrug.

"Sure why not." said Blake. Ruby and Jaune pulled out their scrolls. Being the team leaders, they had everyone's aura bar on their scrolls.

Team JNPR

Jaune: 50%-yellow

Nora: 30%-red

Pyrrha: 68%-green

Ren: 57%-green

Team RWBY

Ruby: 80%-green

Weiss: 62%-green

Blake: 55%-yellow

Yang: 0%-DANGER!

"Wow Yang , how did you manage to get down to zero?" asked Ruby. Yang just shrugged and smirked.

"I fight with my fists. You dont get much more 'up close' then that, im bound to get hit a lot." said Yang proudly.

"Well it lookes like Ruby has the highest." said Jaune. Ruby made a fist pump while Nora seemed dejected that she wasnt the winner.

Ruby anchored her giant scythe to the ground to steady her shot. The lone grimm tensed up, knowing now was the time to strike.

'hmm weird little guy ,you could have ran away a long time ago by now. Oh well...now did i shoot 9 shots or 10 shots in that fight ,hmmm?...im pretty sure ive got a shot left.' thought Ruby.

"Hey guys ive got one shot left in my mag, lucky huh?" said Ruby before turning back to her target.

The two teams stood back back like they were about to witness something amazing.

The second Ruby peered into her scope the grimm attacked. It dashed at her with incredible speed . Hellbent on taking someone with him to the grave.

Ruby was a little surprised on how fast it was, but quickly composed her self. She lined up the beast in the cross hair of her weapon and once its had was in the center, Ruby pulled the trigger.

*click*

Nothing

No gunshot, no recoil, no sound of a grimm sized corpse dropping to the ground.

nothing

Ruby kept pulling the trigger frantically as the grimm was getting closer and closer.

'uh oh, guess i did shoot ten shots!' thought Ruby. The grimm was getting very close only way Ruby could kill it now was with her blade . But it was already anchored to the ground, by the time she pulled it out and swung it over her shoulder to cleave the grimms head off, its teeth would already be in her neck.

Ruby froze. It was too late. The beast was inches away from her. Ruby could see its claws raised , ready to strike at her. She could also see the hate and blood lust in its eyes.

Ruby blacked out, but the last thing she felt was a pair of hands push her out of the way.

When Ruby came too she was lying on the ground. When she got up she noticed Team JNPR's expression were one of shock and fear. She felt something solid near her foot. She looked and saw the severed head of the grimm she was about to kill, the bloodlust still visible in its dead eyes.

Ruby saw Blake and Weiss kneeling down near a familiar shape and color.

Ruby grew incredibly pale when she saw her older sister, lying on the ground , gasping for air,covered in blood with large gaping hole near her chest.

"Yang..."said Ruby in almost a whispered tone before tears flooded her eyes.

a harmless joke , leading to a huge tragedy
