Onyx felt the Harmonic Magic explode outward and let him know exactly that Twilight had finally broken through. He started setting his things down and used his Alicorn power to head to the place that connected them extremely deeply to Harmony. He had explored his section a little bit and was surprised that he was quite close to Celestia and Luna locations. As he looked around and moved to where he sensed Twilight in worry before noticing Celestia also making her way over. He suddenly stopped and started walking away. He mused to himself in the privacy of his mind. 'This is their moment and being together with each other in privacy.'
---With Twilight---
Twilight looked around the strange land she was now in and wondered where she currently was. She was quick to call out in worry hoping that she was truly not alone right now. Her tone was shaky. "Hello?"
"Where am I?" She looked around the strange realm trying to figure out what was going on. She slowly questioned herself allowed sounding like she was hoping someone would tell her where she was. "What is this place?"
She blinked when she noticed what looked and had the coloring of Celestia walking towards her along with another pony darker in coloring, matching her princess. When they stepped into view, she saw Princess Celestia's twin but with darker coloring along with Celestia herself. She slowly spoke in question and worry. "Princess Celestia?"
"Hello, Twilight." Princess Celestia greeted her student before looking at her nightmare Daybreak. Before deciding that there was nothing, she could do to get rid of the creature. As she moved forward, she noticed that Daybreak was following and was only stay close enough to the two of them to hear what was being said. Celestia was quick to praise Twilight on her accomplishment. Her tone had a lift to it. "Congratulations, Twilight, I knew you could do it."
Twilight slowly met Celestia in the middle, terribly confused by there being two of them. Before she started speaking in question on her tone of voice. "Princess Celestia, I do not understand? What did I do?"
"You did something that is truly quite rare in total six Ponies so far in all of history have done before you." Celestia started leading her student down a road while looking at the magical copy of the book floating along with them. Twilight was so confused because this sounded really important. She slowly followed Celestia down the Road when she spotted what looked like Onyx off in the distance. "Star Swirl the Bearded tried to force what you have done, but he did not succeed."
Twilight got it pretty fast and looked up at her teacher, genuinely shocked. She spoke with awe in her tone of voice. "Are you saying what I think you are saying?"
"Indeed, you have done a great deed for Harmony and proven yourself worthy of a mantle of Godhood." Celestia explained while sighing because no matter how she wishes for them not to call her a god, it is pretty much what they are. Twilight was confused before remembering that Celestia did not like the word god at all. She slowly hummed in thought and looked around before hearing Celestia speak the following sentence. "I am slightly curious what kind of Alicorn you will become and what your mantle will be."
Twilight watched her teacher move along and quickly followed and saw various memories of things she had done with her friends in ponyville and her relationship with Onyx. Celestia slowly sang a song about growth and growing up. While Twilight could only smile and sing along with her. While looking over all the things she had done with her friends.
---outside---
Onyx sat near where she was completing the transformation and could not help but admit that hers was way more impressive compared to his. Still, in his opinion, he did not need super impressive to become an Alicorn, and it would not have fit him. Before he notices, the girls freaking out and spotted Discord standing next to him. He spoke up in question. "So has there been anything like us at the level that Twilight was going to be at before."
Discord could only sigh and look at the Harmonic magic wafting off her transformation bubble that only they could see. He spoke genuinely worried. "No, nothing like Twilight had ever been born before."
Onyx only hummed and tried to remember any of the memes and stuff from the wiki, and all he was getting was a blank. 'So I am out of information of the series right at this moment.'
They both watched as Twilight's bubble started floating down and released her into the world and watched as her friend reacted to the new wing with awe in their tone of voice. Onyx looked at the approaching Celestia and slowly hummed in a low tone of voice a song he remembered. While looking around, he could not help that he started chuckling.
---Canterlot days later---
Twilight looked over at Onyx and started questioning him about what he was doing. "Are you really turning down the right to be considered a prince Onyx?"
Onyx looked at her and then remembered that amount of paperwork and all the lessons she had to go through just to get this coronation ceremony to work the way they wanted it to. Before remembering all the lessons, he had already needed to go through, and shuddered. "No, thank you, Twilight, my dear, I am perfectly happy being a high noble and not needing any land or anything like that."
Twilight could only snicker because Onyx literally needed a ton of lessons already to make it so he could make it through the day-to-day as a high-ranking noble pony. She quickly pulled him into a hug while looking up into his eyes. "Are you sure there is no way I could convince you, Onyx?"
Onyx only smiled down at her before teleporting away.
---Ceremony Crowning of Twilight---
Onyx sat on a balcony and looked down at Twilight getting crowned by their great goddess Celestia and could not help but admit that this was the best adventure of his life. He let out a low sigh. 'I am in a fey type of mood lately. I wonder why.'
He heard someone walking up towards his private spot and looked and notice Luna next to him. He quickly greeted her. "Hello Luna, How are you this fine day?"
"I am feeling extremely happy and in a heartfelt mood, Onyx." Luna answered with cheer and looked over at Onyx in thought. "And yourself, master Smith?"
"As well as I can be." Onyx answered back before noticing Discord sitting with him. "And yourself master Discord who has just appeared from nowhere."
Discord only snickered and looked at the ceremony and hummed with laughter on his tone. "As well as I can be Onyx, and good morning to you, Luna."
Luna only scowled at Discord before sighing and slumping down in annoyance. She spoke with a sassy tone of voice. "Your presence still irks me greatly, Discord."
"Thank you for your honesty, your majesty." Discord was much happier with honesty from Luna than what he felt was Celestia's false attempts at friendship.
---Astral Realm---
Harmony and Discord slowly spun in an old stay of dance, with Harmony being that one to first speak up. 'This is truly strange. Is this what you felt when you created your lesser self on our world?'
Discord only hummed and looked at the things that Harmony was sharing with him and nodded because that was pretty similar to what he felt at the start. 'Pretty close, it will go away in a few centuries as Twilight changes and your personalities do not match as well as before.'
Harmony could not help but sigh because, at the same time, she did not want to lose this feeling, but she wanted to keep it at the same time. 'I do not know if I am going to be happy or sad when this goes away, Discord.'
'All things Change Harmony.' Discord only gives these words of comfort to Harmony because there was nothing better he could do about what she was feeling right now. 'But we always keep the memories of them.'
