Shadows Lurking...

•This is a mysterious foreshadow of the next collab-story... What will happen next? And, more importantly, who's against these shy unicorns?! : ~AkoriKitty•

"Raina," Lemon-Lime said, breathing heavily from running down to her friend's house, "do... you... know... anything... about..."
"Sit down, Lemon-Lime," Raina squeaked, "you look, um, tired..."
Lemon-Lime accepted the invitation and sat down on the edge of Raina's cozy blue couch. Raina sat on a cushiony white chair across from Lemon-Lime. "Okay, thanks... I'm, um, more relaxed..."
"Alright. Do you know, um, a spell on how... how to, uh, c-catch moonlight?" Lemon-Lime asked nervously. "I mean, um, if you don't, then, um..."
Raina nodded quickly. "I, erm, I actually do... I learned it when I w-was reading a book... in, um, the library... I can show it, um, to you... if you want?" she stammered.
They traded information and opinions for a while, until Lemon-Lime could conclude that Raina DID have some bottles of moonlight. She told Raina about the magical orb『Read Lemon-Lime's 35th Apprentice Log if you don't understand this!』and how they should try to mix it together with the other ingredients. Raina, out of curiosity, agreed.
Lemon-Lime unpacked a small bag that had been levitating in mid-air this whole time, thanks to Lemon-Lime's magical green aura of... magic.
There were half of the ingredients in there. Raina, using her magic, dropped off the rest of the ingredients (luckily, she had fifteen glow-flowers!).
They snuck outside, into the grassy valley that they'd found the glow-flowers in. They took a while to make the magical orb (Raina happened to borrow an old spell book from the library), but then they finally figured it out and dropped it into the bubbling cauldron.
But what they didn't know was that some-pony had been spying.
Spying on them.
And, with a nearly-transparent zap of blue lightning, this unicorn disappeared into a thundering laughter. The zap of lightning was absorbed into the cauldron. Neither filly saw this happen.
And this zap of lightning wasn't for the better.
The spell was already changed.
