The doors to Celestia's room were surrounded by a golden aura before swinging open and Celestia walked through. She kept her emotions in check until the doors close. She climbed up into her bed and buried her face into the nearest pillow before letting out loudly muffled screams and sobs. After a few moments she lifted her face out of the pillow and sobbed again.
“L-Luna...I-I'm so sorry! I never wanted this to happen!”
She looked over to a picture of the two princesses as fillies. The picture showed Princess Celestia laying in the grass with a much younger Princess Luna laying on top of her head. Both fillies presenting a wide smile across their muzzles. This only makes Celestia sob harder.
Meanwhile outside the princesses quarters. Starswirl the Bearded approached the doors before being blocked off by the guards.
“The princess is not to be disturbed Wizard.”
“Please just let me in. I can help her. I can help her cope.”
“I'm afraid we can't do that. The Princess is in deep emotional pain. It's best that she is not disturbed for the time being.”
Starswirl glared at the two Pegasi guards.
“Let me pass. Or I will have to use force.”
This alerts the guards as they aimed their spears at the Wizards chest.
“Is that a threat old stallion?”
Starswirl narrowed his eyes.
“It's a guarantee.”
“Starswirl the Bearded, you are under arrest for threatening two officers of the Royal Guard of Princess Celestia. You have the right to remain silent.”
Starswirl grinned as he charges his horn.
“As do you...”
The Mage casted a sleep spell on the two guards, causing them to fall over into a deep sleep. Starswirl breathed deeply before pushing the doors open. Celestia, unaware of his presence continues sobbing. He slowly walks up to her before placing a gentle hoof on her shoulder. She jumped, startled.
“O-Oh...Hello Starswirl. What can I do for you?”
“Nothing Princess. The question is What can I do for YOU?”
Princess Celestia looked away from the old stallion.
“I-I don't know what you are on about. But I am fine I assure you.”
He shook his head.
“No Princess you aren't. I'm sorry to hear about your sister. I wish there had been a better outcome. I can only imagine the pain you are feeling right now.”
“S-She's gone Starswirl...gone. I sent her away...to the moon! WHY DID IT HAVE TO HAPPEN LIKE THIS?!!”
“Princess, please. I know this is hard for you. It's hard for all of us to accept that sweet little Luna would turn on us...but you mustn't beat yourself up over it. It wasn't your fault.”
“IT'S MY FAULT SHE WAS SENT TO THE MOON!!”
“PRINCESS CELESTIA!! STOP THIS FOOLISHNESS RIGHT NOW!! Now you listen here! What happened is NOT your fault! This was Luna's doing! It is tragic what has become of her, but for ponys sake you did what you had to do!”
“T-Then why does it hurt so much...”
He sighed deeply.
“Sometimes the decisions that we have to make...are the decisions that are the hardest to make. But they have to be done for the betterment of Equestria. I know you are feeling deep sorrow and pain. But it will get better over time. I'm sorry that this is causing you great pain.”
Starswirl took his hoof off her shoulder and silently left her quarters. She watched him exit and close the doors behind him before dropping her head with a sigh.
“You have no idea....”
