The Celestial Guard

A scream, shouts, the sound of blood running and a whit alicorn mare ran off into the forest, Swift Hooves lay on the ground,bleeding profusely from his neck, all four hooves broken and twisted beyond recognition. Three other unicorns circled him, preparing to end him. The leader of this pack stood tall, with a red coat and deep blue mane. He looked at Swift Hooves and spoke.

"You should have given yourself to Discord, when he have you the chance"

"I would never betray the royal family for swine such as yourself, Stoneheart." replied Swift Hooves, coughing up more blood.

"So be it, I feel sad to kill such a worthy opponent", a smirk appeared on his face and his horn glowed red.

Suddenly, a beam of pure energy flew out from the woods, killing two of the three unicorns and hurling Stoneheart into the thick trunk of a tree. Stoneheart groaned as he slipped into the unconscious. Swift looked towards the source of the beam and saw a large black figure.

"I'm sorry Swift Hooves", said the figure, as a blue bolt of magic tore into his body. He could feel himself falling and falling and falling.......

2000 years later,

Princess Celestia and Luna sat on their thrones, tending to the daily business of Equestria. On the walls were large stained glass windows, depicting significant events of Equestrian history, the defeat of Discord's tyranny by the royal sisters, the discovery of the Elements of Harmony, Discord's second defeat by the mane six and the Coronation of Princess Twilight.

                  Then there was "That One", the one nopony dared talk about or mention. It stood over the entrance so that only the princesses or exitees saw it. It depicted two  ponies, the first one, a white alicorn mare about the height of Princess Cadence, with a flowing, multi-coloured mane, her cutie mark was similar, if not identical to Princess Celestia's. There were tears on this pony's face as she stood in the forest unable to look at the bloody, mangled body of the other pony, a stallion. This stallion had a pure white coat and golden mane, his horn was narrow and longer than the typical horn and ,his cutie mark was a moving hoof. If one payed a little more attention to the stained glass, they would see that there was a faint cyan glow on the borders of both ponies' cutie marks, as if they were connected somehow.......

                   Princess Cadence was idly chatting with her husband ,standing beside Celestia when she felt a surge of emotion from her, it was filled with regret, despair,....and love, something Cadence never knew existed in her aunt. She looked over at Celestia,  she saw Celestia longingly staring at the stallion portrayed on "That One". Celestia looked to her left, catching the gaze of Cadence and looked at the ground, blushing. Cadence's mind entered a mind buck, and she started to ask herself, " Who was that stallion?". "

                   Princess Luna stood at the balcony outside her bedroom preparing to call up the stars, when a familiar pink blur appeared. For a second she thought it was Pinkie Pie, but that would make no sense, but Pinkie Pie made no sense anyway.

"Aunt Luna, may I ask you a question?", Cadence said eagerly.

"What is it that thou requests of us?", replied Luna ,unsure to where this would lead.

" Do you know anything about the stallion in the stained glass window?."

At first, Luna paused, then motioned to speak, and then again paused to think about what to say.

"We have do not, but if you really desire, we will ask our sister in the morning"

"Thank you" replied Cadence, giggling to herself, and speeding down the corridor to her husband.

  "What did she say? "asked Shinning Armour.

  "She doesn't know that stallion, but she will ask Celestia in the morning",replied Cadence

  "You know honey, maybe you should just forget about this, if Celestia hasn't told us about him now, I doubt she ever will, "said Shinning with a worried face

  "Where's your sense of adventure Shiny? Are you afraid that your wife may end up with too much to handle? "Cadence's excited smile began to turn into a smirk

  "Yes I do fear for you honey and I don't want you or my boss to get hurt because she will kill me to get back at you probably."

  "Awwwwwwww, that's so cute come here", Cadence dragged Shinning into a deep passionate kiss and smiled at him with a suggestive wink.

  "But I have to meet the new recruits, and-",Cadence using her magic grabbed her husband by the ear and slowly dragged him to their chambers.

The next morning, Celestia arose from her bed sheets and mumbled to herself, cursing the fact that her mane refused to untangle itself. She walked to her balcony and prepared her daily spell rise the sun. When she had finished, her sister approached her calmly clearing her throat to grab her sister's attention. Celestia still in a daydream was startled, jumped into the air, before realising it was her sister, she looked away, attempting to hide her red face.

"Ever since we were born, we have never see our big sister daydream, let alone blush, may we ask, what is wrong?"

"Some thing w-wrong? N-no surely you are mistaken little sister," Celestia was still blushing, unable to make eye contact with her sister.

"We have never heard stutter when being asked question. So we ask again, what is wrong?"

Celestia sighed and made eye contact with her sister and said "Its personal, Luna very personal."

Unconvinced Luna continued, "Has it anything to do the stallion in the stained glass window? "asked Luna

"Yes..no maybe just leave it a-"

"We were born forty years after you, and as we have no knowledge of this stallion. He must have lived during those forty years. Were you and this stallion very cl-."

"JUST LEAVE IT ALONE LITTLE SISTER!" screamed Celestia, her face was contorted into  face of rage. A little shocked, Luna slowly carefully backed out of her sister's chambers ,fully aware of the angry gaze her sister was giving her.

                                                       However, Luna was not discouraged, instead she was even more interested with this stallion. She would have sought out Twilight, but she was on leave with her friends in Ponyville. So she sought out her niece.
