Celestia thought about the events that led up to where she were now. How if she had not gone in the woods that night Skye might not have survived to see the daylight. She had became very surprised when he showed signs of being immortal, much like her, but instead of the original spell used when turning her and her sister immortal, it had given him immortality that would change his form every 500 years. It was nothing serious, as he kept his memories, but changed mane and coat color. Judging from what the scientists had said (It had taken a lot of time for Skye to be able to let scientists near him) they had learned that not only was a type of immortal like her, but the reason why his body was forced into those transformations was because his power had been rapidly increasing.
When she had brought him in, he held magic next to a fully grown unicorns, but he could not control it. He had stayed with her and soon learned it, and to keep the nobility line in check from justifying him as an outsider, she had made an announcement that he was "crowned" Prince Skye, Eternal Flame. It took after her own title as the Eternal Sun. She had watched him on as he studied academics and even politics. He had learned enough of how to deal with nobility to even help her! Celestia smiled at the thought.
Celestia would soon depart from Day Court, as she was needed by her student, Twilight Sparkle. They had met during the entrance exam to her school, and Skye thought it amazing that such a small unicorn could hold that kind of power. She guessed it reminded him of himself, so she took her under her wing, teaching her. Twilight was, interesting indeed. She spent time inside, rather researching than going out partying like her previous student. She had also seemed to take an interest in Skye, at least a academic one, pestering him about the differences between him and her. Each time Celestia caught her she would begin to reprimand her, only for Skye to interrupt, and tell her he was fine with it. He had definitely come far from the small colt that was afraid of the dark, and afraid of any profession within the scientific field.
She liked to think that she had rubbed off on him, is voice had retained that smooth ocean-like tone from so long ago, yet it had matured, and turned into brief waves, which turn into a crackling tsunami when angered. She had seen many times when he was angry, not at her, but at himself. It was mainly in his earlier years that he had done so, but had become calm and collected as the years passed by. Speaking of the devil, Celestia,cracked open a brief smile, eyeing him as he made his way towards her in the throne room.
"Hello Mother!" Skye said happily, trotting along till he reached the end. He had taken to calling her 'Mother' in place of Princess Celestia. While she knew it probably for the best that he didn't, he had grown up with only one positive solid in his life, her. Skye has seen guards come and go, maids take leave and never come back, he had even seen her previous student, Sunset Shimmer, disappear. They never changed, so she allowed it, the nobles couldn't call him out on in anyway, they only know what they were told. Not Skye's true origins, and they'll never know.
"Hello there Skye, how are you feeling today?" She replied in earnest.
"I'm great actually, had another bout with that dream I told you about but nothing bad." Skye said back. Recently, he had begun to have dreams of a large blue alicorn, her fur near black as the night. It was obvious that he was talking about Nightmare Moon, the corrupted version of Princess Luna. This meant that she was going to return soon. She would need to talk about the plan to Skye, so he did not seek her out, it was much more a test for Twilight, so she spoke.
"I know more of this dream you speak of, we will talk about it later, but right now, I ask that you bring this letter to Twilight from me, if I'm guessing correctly, she would be in the library as usual." She finished, keeping her composure at the look of Skye's pouting gesture. He was trying to get her to laugh, but she would not let herself fall easily, instead she called him out on the loss.
"I see your still trying to perfect your gaze, you have lost this round young one, this brings us to 75 to 52, better luck next time." She said, beaming a smile at him. Skye sat there, realizing he had lost, and just as quickly as he came he went to go give Twilight the letter. The timetable had moved up greatly, due to Skye coincidentally confirming her suspicions that Nightmare Moon would return. Hopefully Twilight could bring back the Elements of Harmony, and bring back her sister, she missed her, and likely, would love Skye the same if she were ever to return. 'She will return, I should not stress so much. I trust in Twilight, I have to'. She could no longer wield the Elements, the last time she had used them were the initial fight with Nightmare, so instead her sword had become the Solar guard, while the shield remained diplomacy at best.
She had faith that in the coming hours that Twilight could solve it, she just needed a push in the right direction.
