Whirlwind and Star ran outside into the shell fire, and Whirlwind took off. Star made herself a magical shield, looking down to her flank shortly after she did so and saying to herself quietly, imagining how similar it was to her cousin Twilight's, "This one's for you, Twilight." Normally, a feat like what Star was about to do would be impossible, but the positive feelings she felt flowed through her and enhanced her magic as well as the fact that her armor enhanced her magic slightly. Her hooves dug deep into the ground below her, the cobbled stone road crumbling beneath the sheer weight of her spell.
One, two, three… ten… auras surrounded Star's horn, covering it in a shimmering crimson. "And…" stuttered Star slowly, quietly, putting significant effort into even speaking for how hard she was working on her spell, "This one's for you, Dew!" Star squinted, gritting her teeth and putting at least twenty more auras around her horn, glowing like a crimson sun… a star… just like in her name. A gigantic shield surrounded the entirety of the camp, and Star summoned several hundred magical, explosive weapons and dumped them down around the edge of the camp. "Those ponies are gonna regret even coming here," Star thought to herself. She could sense everything now: Lasso tackling the Lunar Republic soldiers on the ground with her sword and her lasso, Whirlwind taking any incoming magical missiles with her shield and tornado techniques, Bubble bouncing on the heads of the enemies to knock them unconscious, Sketchy shoving through the large crowds with her sword in her magic, Pinkie Pie bouncing along with Bubble, Rainbow Dash taking out several hundred at once with her rainbooms every half hour or so. But that was all nothing compared to Star's magical weaponry.
"Everypony get out of the way! Into the force field!" Star sent a telepathic message to everypony in the area why may be affected that wasn't the enemy. As soon as Star made absolutely sure everypony she cared about was inside, she powered the force field up twenty times more, thrusting the enemy away. Then she put out the real shocker: literally. Star Sparkle had the first part of her name for a reason: she had minor control over the weather in the area around her. She summoned several thousand thunder clouds, but then she sensed another pony fly out of the area. "A gray young mare… a pegasus… dark gray, fluffy mane… she's helping with the thunder clouds! But… how does she do that without being shocked?!" thought Star. "Thunder Cloud, at your service," shouted the pegasus over the magic's noise, flying over to her and saluting. "Just keep doing what you were doing, it helps a lot," Star sent a telepathic message for lack of ability to talk. It would have been drowned out by the magic anyways.
"I'm on it!" exclaimed Thunder, flying up to continue placing the clouds directly above the highly concentrated enemy areas. "You appear to be immune to the lightning coming directly from the clouds," Star sent her message to Thunder. Thunder simply thought, "Yeah, that's my special talent," and Star heard her. "You can fire the spell to set off the clouds now," thought Thunder, "I'm safe above them all." Star confirmed her and then shut off the telepathic signal exchange. Star then set off her spell, and she heard the lightning crack overhead, several thousand bolts at once. Star tensed up at the very sound of it but stood her ground, her hooves pressing even harder into the ground as a few stray, secondary bolts that were not aimed and couldn't have been hit the shield and she had to reinforce it.
Star continued sending the signal until the clouds were fresh out of thunder to roll and lighting to crack. It had been at least two hours of straight, hard magic, and Star's strength was fading, fast. She struggled not to stop her protection spell altogether. She suddenly started thinking of Whirlwind… she sensed that she was inside the shield, but she didn't know why else. "She was the one who got me into all of this," she thought to herself, justifying her various random thoughts, "Or maybe it's just because I'm tired." Suddenly, behind closed eyes, Star felt a hoof on her shoulder.
"Star?" asked Whirlwind, "You're really great, you know. All the enemies have almost evacuated the area, and by the area, I mean all of Canterlot. They're leaving now. But… I was wondering if you wanted a little help." Star opened her eyes just a smidgen, just enough to see Whirl right next to her. "It's… getting dark," said Star, putting huge amounts of effort into speaking, "It's… going to get… cold soon…" "True," said Whirlwind, "Here, this might help." She wrapped her wing around Star, tilting Star's head down and looking down as well so Star could tap into her magic reservoir. It was relatively small, as all pegasus reservoirs usually are, but it was useful nonetheless. "This thing is gonna have to get bigger," thought Whirlwind, Star heard her thoughts because she was tapped into her magic. Star nodded then thought, "But I don't have any strength left do so…"
"You do now," said Whirlwind, wrapping her hooves around Star's neck and holding her tightly. A magical surge caused the shield to increase in a huge amount. "You trying to encompass all of Canterlot?" thought Whirlwind. Star thought, "That'd be nice…" "Okay," thought Whirl, "Then follow my lead." She smiled, leaned in and pressed her lips against Star's. Star wrapped her hooves around Whirl, their shield now encompassing, literally, the entire city. In fact, screw the city; it was going more towards the entire mountain.
When they finally expelled all the enemy soldiers from the entire mountain, Star and Whirl collapsed. "You… did great…" said Star. "You… you did great too," said Whirl, "I think Twilight would be happy with you now, Star." "I…" Star stuttered, "How'd you…" "Magic reservoirs, remember?" asked Whirl. "Well, lookie what we've got here…"
"Pinkie Pie?!" exclaimed Star and Whirl pretty much in synch. "Yesserooni!" Pinkie, "Oh, and I get to plan the wedding. I've done it before, you know!" "Pinkie," said Lasso, "I don't think…" "What do you think, Star?" asked Whirl. "Someday," said Star, sighing, "Someday…"
