Princess Celestia was in her royal bathtub. It was one of the most, if not the most beautiful bathrooms in all of Equestria, its wide walls made of marble adorned with golden motifs of the sun, the bathtub being more of an indoor pool made to give the ruler of Equestria the most pleasant of times. Currently she was busy pouring bathing salts into the bathtub.
“Ah... this is life.“ said Celestia.
She was interrupted by a heavy thumping on the door.
“Ah, come on!“ she groaned, “What is it?” she shouted towards the door.
“Ma’am, sorry to interrupt you,“ a male voice shouted back, Celestia recognized the voice of one of her personal guards, “but the sun, it's changing color!“
“What do you mean by–“ suddenly a strange feeling began to fill Celestia, she could feel a lump forming on her throat, tension began to form on her withers, and she could clearly feel something alien affecting the sun –her sun–, this caused her to immediately jump out of the bathtub and out of the bathroom, ignoring the blushing guard that tried not to look at her naked, wet figure, she continued walking towards the balcony in her room, and as soon as she opened the doors that lead to it, a terrible sight caused her to reel back in shock:
The sun –HER sun– had become red, bloody red.
She managed to get ahold of herself enough to turn her head towards the still blushing guard, said guard cowered before her gaze, which was full of anger, “Ready our troops, I want two units ready NOW! “ she practically shouted.
The guard quickly regained his composure and he rushed outside the room. Celestia´s horn flickered with magic as she summoned a parchment and a quill, lifting both with her magic she began to furiously write down a letter directed towards the now Princess Twilight Sparkle:
To my faithful student
Dear Twilight,
I’m sure you already saw the new color in the sun, I want you to gather the elements of council of friendship and be ready for when I call you, in the meantime investigate any possible causes of this phenomenon.
We will be doing our part here in Canterlot.
Princess Celestia
She quickly rolled the parchment and with another flick of her horn the parchment disappeared in green flames.
Celestia closed her eyes as she began to concentrate on the magics that permeated the sun, she could feel her own power influencing the sun and she also felt something… foreign. This power was moving around, encircling the sun; she tried to push it away with her own, but every time she tried to influence it, it simply didn’t move. This power felt... absolute and… unnatural. She was interrupted by a flash in the room.
A dark-blue alicorn stood in front of Celestia, in her face she could clearly see worry, “Sister! “ she shouted in an actually manageable tone, “Somepony is messing with our moon! What is the meaning of this!“
Celestia opened her mouth in shock. “The moon? Too? “
Luna raised her eyebrow, “Too? “ she repeated, then it hit her. “Is the sun affected too? “
Celestia silently lifted a foreleg and pointed it towards the now open balcony. Luna turned her head towards it and the sight of the red sun made her gasp and reel back in shock.
“W-who? “ she managed to mutter. “Why? “
“I don´t know sister, but we are going to find out. “
