Okay, I've done karate, fencing and Bladecasting practicing, so all that's left is magic. Astral screwed her eyes shut and concentrated. As always, her magic had improved after the last loop, and her control had also lessened; she almost blew out the windows going over the sound spell.
Once that was done, she trotted downstairs to meet up with her mom. Once more, Twilight's reaction were exactly the same as in previous loops. Astral briefly wondered if there was a way to speed up her reaction, but banished that thought.
After making sure her mom had caught up with all the relevant data, she asked "why is it that when my magic increases, my control lessens?"
Thankfully, that was actually a very common question, one Twilight knew the answer to. The alicorn thought of how to describe it to her daughter, before brightening. "Think of a tap. If you have a tap where there isn't that much water,you have to turn the tap all the way for water to come out. And if you use somepony else's tap with a stronger source of water, you can accidentally overshoot, and end up splashing yourself."
"So, my magic is the tap?" Astral squinted, tilting her head slightly.
"Your magic is the first tap, the weaker one. Someone, or" her face darkened "something, is giving you magic."
"Wait, this magic isn't mine? I didn't even know that could be done!"
"It can't, but it's the only explanation. Somepony is giving you their magic at the end of each loop, and is increasing the amount every time as well; that's why the others are . .overloading, while you're okay, your body is used to the input." Twilight paused, before squinting at Astral. "Sweetie, are your joints starting to hurt? Any headaches or jittery feelings?"
"Actually, yeah, my joints felt weird when I was a princess" seeing her mom's weird look, she waved a hoof "long story. Is that a bad thing?"
Twilight placed her front hooves together and breathed out. "First off, I don't want you to panic" she said. Bad sign, Astral thought, dread starting to form a pit in her stomach.
"But?"
"But a unicorn body can only hold so much magic before it starts to break down" the words were rushed, like she didn't want her daughter to hear them, but she did.
"I'm dying?!" Astral shrieked, stumbling backwards in terror.
Twilight scooped her up in her magic without a second thought, hugging her close. "Sssh, it's okay, there are ways to fix this" she said, nuzzling her gently. "You just need stronger spells to take up your magic."
"You mean the intermediate level" Astral sniffled.
"Yes, you can practice for this loop, and take it in the next loop" Twilight messily wrote something down on an envelope, and handed it to Astral. "Just give this to me next loop."
Alone, Astral contemplated her mother's words.
Someone is giving me their magic, but who? And why?
