Taking a lesson (Post- Eternity's Light, SPOILER WARNING!)
"Okay class, would you all like to take a seat" Twilight said as she waited for her 8th Grade class to settle down.
"What are we going to be learning today Miss Sparkle?"
"Actually, you get a little treat, we'll be having a guest come in to teach you a powerful school of magic"
"Who is it Miss?" A unicorn at the back asked.
"That would be me" Firestorm said as he appeared at the front of the class, to everypony's surprise.
"Where'd he come from?"
"Sorry I'm a bit late twi"
"It's perfectly okay, this is Prince Firestorm everypony"
"And today, I'm going to be teaching you about burst magic" Firestorm said, as he wrote Burst Magic on the blackboard, the unicorns looked at each other befuddled.
"Um, might I ask Sir?" A unicorn raised his hoof nervously
"Sure shoot" Firestorm said, pointing the chalk at him.
"What exactly is, Burst Magic?"
"I'm very glad you asked that, what's your name son?"
"Sparkstar, Sir"
"Okay Sparkstar, I'll be happy to answer that question, if you come and lead the class out of this room, and into the training yard, this is gonna be a practical lesson" he said, as the young unicorn came nervously to the front, opened the door, and lead everypony out and into the training yard, it seemed Firestorm had booked it out.
In The Yard...
"Okay everypony, I've set up a dueling ground for you to practice burst magic. Now this school of magic is mainly defensive, but can also be offensive in a wide range, dependent on how charged the spell is before you release it" Firestorm said, as he pointed to twilight and told her to stand on one end of the dueling ground.
"What do you want me to do storm?"
"Hit me with a thunder stream"
"If you say so"
"Just a word of warning class, I trust twilight not to hurt me that badly, so don't try this at home" And with that, Firestorm began charging his horn, it glew gold, then Twilights began sparking purple.
"In your own time twilight, Fire away!" And she sent a stream of electrical energy straight towards Firestorm, he then raised his horn, and it pulsed off, and encased him in a large golden bubble, which then absorbed the electricity, and channeled straight into Firestorms horn, he then dispelled the shield.
"So as you saw, that energy shield soaked up Twilights attack, allowing me to draw from it. I can now convert this into another power type" His horn then began to glow blue, as he released the pent up power in a huge deluge of water, soaking his class, they burst out laughing at their sudden soaking, Twilight then looked at him, cocked an eyebrow and settled down her class.
"Do we have any questions?" Twilight asked, and a unicorn raised her hoof.
"Yes Carmel?"
"How many different elements can we convert this power into?"
"That's a good one, You can convert the absorbed energy into anything you want, as long as you can think of it, you can also repel the energy when it connects, like a mirror, any more?" Storm asked, as another unicorn raised his hoof.
"How does Burst Magic gain strength?"
"It depends on how much energy you absorb, or for how long you charge the spell. But if you overcharge it, and your body isn't used to that capacity of magic energy, you start seizing up and the magic backfires and can put you in hospital" And another raised their hoof.
"Can two ponies combine burst magic? and increase how much magic they can handle?"
"Actually, I'm not sure, how abouts a volunteer..." Firestorm said as he looked through the class.
"Sparkstar, come stand next to me, Twilight, can you pick three more?" He said, as the nervous unicorn stood next to him, and twilight picked three more out, Two mares and a colt.
"Right, you three, are going to combine your powers into a burst stream, and me and Sparkstar are going to drain it, and convert it into water, okay buddy?" Firestorm said as he looked at Sparkstar.
"Okay sir, Do I put up the shield?"
"That's the idea of the test, I'll give you a boost to show you what happens, Twilight help these three, seems fair to have an Alicorn on each side" And twilight went and stood in the middle of the group, Firestorm lit his horn, and Sparkstar primed his, it glew a brilliant silver.
"We're ready our end Twi, yours set?" he asked, as four horns lit up, sparked off into one centre point.
"Ready!" Twilight said relaxed.
"Fire!" He yelled and they sent off a powerful white stream, Sparkstar attempted to spark something off, and managed to raise a barrier, the beam went straight through it, smashing it like glass, they then cut it off, and Sparkstar looked at firestorm squeamishly.
"Sorry sir" he said, as he hung his head in shame, Firestorm then put his hoof on the young colts shoulder.
"Hey, that was your first time, that was incredible, you just need to bolster it that's all" Firestorm said, the young unicorn looked up to see the rest of the class applauding him. Firestorm then materialized a little watch, with a dial and three different areas.
"This will tell you how much magic your using" First he pointed to the green zone "This is the right sort of area you want to stay in" he then pointed to the orange zone "This is veering on dangerous, don't stay in this area for too long" and pointed to the red zone "Stay out of this zone, this level of magic is gonna put you in hospital"
"Will it get harder for me to get to the red zone as I get stronger?"
"Yep, I've not had magic overload for about twenty years now?"
"Wow, you must be good sir"
"Shall we try again Sparkstar?" Firestorm asked, and the unicorn charged his horn, and the dial began to rise, the other four readied the stream.
"Just a little more!" Sparkstar strained, as the dial began to creep into the orange zone, and a barrier pulse sparked off, Firestorm then added his power, and the dial shot back into the green zone.
"What has happened sir?"
"The dial now shows our combined powers, that won't come out of the green zone" he said, as the group fired off the stream, and Sparkstar released the shield, the beam collided with the shield, and the shield began to soak it up, the class was cheering, they stopped the stream, and Sparkstar began to absorb the energy as firestorm cut off his power, he began to strain under the power surplus.
"Now convert to a new element" Firestorm said, as his horn changed from silver, to royal blue, he then released it, and a swirling blue ring of water appeared round him, and began to raise a huge column of water around him.
"Well done sparkstar!" Twilight cheered, then she looked at firestorms dial, it was almost at red, firestorm looked at it and shouted to Sparkstar.
"Release it Sparkstar! Your in red!"
"I can't!" He yelled, as the column began to spark silver. Twilight backed the rest of the class away, as Firestorm readied himself.
"Alright Sparkstar, I'm going to take control" He primed his horn, and he began to siphon off the column, Sparkstar pointed his horn towards Firestorm, and the dial began to decrease, and the column began to die down. As the column finally dissipated, firestorm leapt up, and burst out the excess power. As he slowly came down, he looked at the class, and smiled.
"That, was incredible Sparkstar, I've never seen that level of power from anypony, at this stage" He began clapping, and so did the rest of the class. "Okay, here is an energy dial for each of you, now I want you to go from this lesson, and find out your magic limit, and twilight, I want you to mark it, and report back to Celestia, I'll then come back with another lesson"
"Okay, thank you firestorm, Class dismissed" Twilight said, as he materialized an energy dial for each of them as they walked out of the courtyard.
"Do you think you should send a letter to the parents?"
"Just as a precaution, thanks firestorm, catch you later" Twilight said, as she took some parchments and her enchanted quill started scribbling down the warning letters.
"See you Twi" he said as he charged, and disappeared in a blast of light.
"I really should've written the letters myself..."
