Pulsar and Sunset were finally happy again for a couple hundred of years more, no new issues, no more large declines. Ponies were growing unrestful and Pulsar knew why, he kept getting more and more visitors asking about magic, the difference between the pony races' magics, and today.
"What's the most powerful magic?" This was a trio of a unicorn, earth pony, and pegasus.
They stood outside his home where he held his counsel.
The sun was high in the sky and he was smiling.
"I can tell somepony had a talk with you three and you aren't exactly the best of friends."
The cream pegasus spoke, his voice angry, "that wasn't our question!" He had noticed that ponies had become less respectful to any alicorn.
"Well, instead of an answer...how about I show all three of you?" Sunset was vacationing on the other side of the mirror at the moment, she had continued to give guest lectures at the Canterlot High School in his place as he was often busy with countless counsel questions. There was a line of ponies behind these three.
"We want an answer!" A pony called from the giant line behind him.
Twilight was teleported right to him, cut short from her own counsel hours. She had a diminishing amount of visitors, but Pulsar had an infinite number.
"So...this is where they all are, huh. Pulsar, when did you become more popular than me?"
"Since we stopped believing your lies!" A pony from the crowd called out.
Pulsar could feel something press from the EverMore.
"The change of an Era."
The Prince of Magic saw the mass of shifting cosmos above the ponies and an idea hit him.
"Pulsar, you had a spark in your eye," Twilight spoke up.
"Twilight, what is the strongest magic of all?" It had been quite a while before she made a show of it.
"The magic of friendship, you know that."
"And where does it come from?"
"Us."
He smiled, "Princess, this is where it enters my domain," he stood from his haunches, "the magic of friendship comes from where all magic comes from. That's a place I can't completely disclose as my research is not done on the subject, but it comes from out there," he pointed his hoof up.
"What?!"
"Oh, great. The Prince of Magic fell off his rocker."
"I see you need some more guidance, apologies Twilight," his horn crackled and the sun quickly went to the side of the side and the moon appeared on the other side, stars filling in the sky.
"Comes from out there?"
"What is he pointing to, the stars?" The ponies were no longer dissatisfied or unbelieving, but curious.
Pulsar smiled, he was going to test the EverMore here and now on his namesake and his horn boomed, the entirety of Equestria shook, large bolts of magic were flying off his horn. He would not use his gem, Magician's Pride, to amplify this. He was barely controlling it as he could.
"Celestia, Luna...they were great mages because they had a direct connection to this as well. I have researched some and I can reach almost directly to where magic truly comes from."
"What...what is he doing?!"
"This is why unicorns have the best magic!"
"No, ours is making the earth quake!"
"Whatever, we can fly out of whatever he is doing."
A star in the sky is shining bright and the ponies bickered while sweat formed upon the alicorn's brow.
The star shot down to Equestria as a giant beam, larger than the landmass of Equestria and came perilously close to everypony.
"PUUU-UUULSAAAAR!"
Sunset teleported next to her husband, having come from across the mirror, "I saw a giant beam and...what in the name of CELESTIA?!"
The ponies were silent as the beam raged incredibly loud above their heads.
Discord came next, "did...did somepony just-. OH!"
The beam ended after a long minute and the sat was missing for a moment in its original place before Pulsar put it back.
"THAT!" He huffed, "is where magic comes from. Nopony has the most powerful magic alone!"
They were gathered around him in a crowd, staring in awe.
"Pulse, did you move a star?" Twilight asked.
"He, he called to magic itself and it obeyed him, he demanded it and it was bent," Sunset spoke.
"Never in all my life did I ever think I would meet someone who had more destructive potential than Tirek. I'm glad you're on our side, Pulsar," Discord fell onto his rear.
"Ponies! Heed me as Prince of Magic and the everlasting flame of it. Magic comes from our cosmos and friendship is our link to be able to use magic."
Starlight was behind the alicorn, having come out of his estate to see the commotion.
He flapped his wings, "the most powerful magic of all is the magic of friendship."
They were staring at him and at the sky as if waiting to see the cataclymic spell again.
"Everpony, counsel is closed, dismissed."
And the crowd stood, galloping, teleporting, and flying away.
Staved it off longer, my child. Impressive.
