(Celestia's P.O.V)
Celestia smiled as she trotted to her younger sisters room. Her purple eyes lit with excitement as she held a dark gray tome in her magic. She had just received it from the griffon nation, it was something Luna had shown interest in getting when she heard about it. Luna having any interest in anything was very rare even if was just some myth filled book mentioning foal tales with a darker twist. 'She's going to love this surprise' Celestia thought smiling at the thought of making Luna happy. She arrived at her younger sisters doors giddy with excitement.

"Luna open up" she called softly. She waited a few moments for her sister to open the door. That was not what happened.

"Luna it's Celestia open the door" she said louder with a worried tone. Her guards had seen Luna enter her bedroom so it made no sense why she wasn't answering. If... IF Luna was asleep she would have woken up now. Celestia sighed deciding to go on in. She turned the door knob and walked in with a frown. She flicked on the lights lightening up the bedroom considerably. She noticed her sisters body on the ground and instantly assumed her younger sister had passed out from exhaustion but the truth was much worse. Celestia trotted over to her sister and what she saw would scar her for life. Her baby sister had a dagger buried into her heart and was bleeding out quickly. That wasn't the worst thing though as she could smell basilisk venom in the air. "GUARDS FETCH THE HEALERS NOW" she shouted in her Canterlot voice picking Luna up and applying pressure to the wound as she cradled Luna.

Hours later

Celestia sat by her sister holding her hoof. She stroked her mane with her other available hoof. Luna's dark blue coat was pale, and her mane had reverted back to it's light blue appearance from when she was a filly. She also had an Iv in hoof. Celestia while concerned was also believably angry. Not at her sister of course ,but at those monsters who pushed Luna to this. Luna never should have been pushed to this and Celestia would make the ponies who were responsible suffer. Her normal purple eyes had changed into the look of fire. Before Celestia did anything else she would see how long Luna had suffered. While Celestia was as practiced as her sister she could access memories. Her horn glowed with the golden aura before she touched Luna's head.

Memories

Celestia stood stock still and focused more magic to bring in one of the first times her sister had been bullied. She was shocked to find this was when Luna was close to being a teen at the age of 12.

"Oops" snarked a green pegasus colt with dark grey eyes that bordered on black. He had tripped Luna making her drop her books.

"You tripped me" Luna accused angrily as she got up making the colt snort as he got in her face.

"So..." he said trailing off.

"So that's mean" Luna said huffing making the colt laugh.

"No this is mean" he said shoving her back. His accomplices, a grey earth filly with blue eyes and a red earth colt with green eyes, laughing at Luna.

"I'm telling my mommy and daddy" she said trying to intimidate him and his cronies.

"Awww... the false princess is trying to scare us" said the filly smirking.

"Run home to mommy and daddy faker" said the red colt making Luna tear up as she ran off sobbing. A thestral colt, unicorn filly and a pegasus filly and colt followed her with concern in their eyes.

Celestia watched in anger as those three foals had the audacity to bully her sister and to call her a false princess ,no less. Celestia sighed as she realized they had put her off telling anypony. They were young but also old enough to know better. With a sigh she moved onto the next memory.

"YOU IDIOT" shouted a angry teenage colt as he smacked a 14 year old Luna sending her sprawling.

"I'm sorry" she sobbed making Celestia bristle as she tried to blast the colt only to be reminded this was a memory when it passed through him. Celestia sighed knowing she would be angry as she sat down to watch this memory to understand Luna better through this.

"Ya can't do anything right. You were flirting with him" he snapped.

"No. I swear I wasn't Kill ,I swear" Luna sobbed as he stomped on side making her scream in pain only to be muffled when he pressed her muzzle to the floor. Bruises littered her side as his beating continued for several minutes before the colt stormed off.

"Let's get back to the pack before I kill him with my bare hooves" said a grizzled older voice as a black stallion with a vivid crimson mane stepped out from the shadows. Luna nodded her head as she stood up a very prominent limp in her movement. They stuck to the shadows until they got to the line of trees. "You first pup" he said softly making Luna nod and stand still til the sound of cracking bones could be heard. Celestia watched the memory in shock as her sister turned into a white and purple wolf with a blue star on her head that was only just shorter than Celestia right now. The stallion followed her shifting into a crimson wolf who was about a foot and a half taller than her. He nodded towards the trees as he jogged off with Luna following with a limp. Celestia decided she would continue her investigation once she had a chance to process the information. She lit her horn and left the memory realm

Current world

Celestia tucked her sister in before kissing her head softly. She left the room trying to make hardly any noise, and succeeded. It was unusually quite on the way to her room. She assumed the word had been spread and nopony wanted to upset her. Celestia walked into the main foyer of her quarters to get another shock.

"Skye!"

Author's Note

So Luna's secrets have been revealed and the eldest sister is back. Honestly I've wanted to write a werepony story for so long. That's obviously not the main purpose here but I thought I would include it anyway. So there are probably a few questions on Luna's coltfriend Killer. You probably wonder if Luna was in an abusive relationship why wouldn't she leave it. Well the reason is very simple: Killer is her mate. She loves him unconditionally even he does beat her. His crimes were punished by one of my personal favorite ponies who will be in the story in the future. If you're wondering why Luna's family never questioned the bruises is because they were never seen by them. She hid them with makeup and she heals quickly since she is a werepony. They never knew she was a werepony, had a boyfirend, or that she was bullied. There will be chapter in the next week I promise. Maybe even sooner if I have inspiration. With that said:
Goodbye, my readers.
