"Say, Smarts, have you noticed it getting colder in here, or is it just me?" Sally was right; it was getting colder. The temperature had already dropped by 10 degrees. Suddenly, an ice fiend materialized outside out of dark blue crystals floating in the air. It was a strange creature, skinny as a skeleton, and commonly grew well over 20 feet tall. They were also known to be able to freeze whole cities on a whim. It then raised its terrifying head.
"That quill you have is far too powerful for mortal hooves," the ice fiend said, "give it to me, and I shall let Ponyville stand."
"Heck, no!" Sally shouted at the 2-story tall abomination. She grabbed the quill out of the air, and started scribbling down something on paper.
"Sally! What are you doing?" Sally was drawing a medieval mace on paper, though quite hastily and it came out lumpy and uneven.
"What does it look like I'm doing? I'm gonna try to save Ponyville!"
"Sally! That quill has the power to make animate objects come to life, but that doesn't mean tha-" he stopped short as the medieval mace fell to the floor with a metallic clang. He weighted the weapon with his magic, and, confident in its power, he engaged the ice fiend.
Smarts' first strike took the monster took it by surprise. It reeled back in pain as his left hand got shattered. "You shall pay for what you have done to me." The monster growled. It reeled back his head, and breathed an icy gale from its mouth. Smarts quickly leapt to the left, and the rock he was standing in front of froze into a block of ice. It then fired a long string of icicles, sharp as needles, at Smarts, who deftly used his magic to reduce the sharp icicles into a fine powder snow. Smarts leapt up the monster's body, and swung hard at the ice fiend's unprotected skull. The force of the blow shattered the skull of the monster, but Smarts' weapon immediately dissolved into black ink. Smarts made a mental note of how much damage something made of ink could dish out. Without its skull to protect it, the ice fiend's body was quickly riddled with fractures and cracks and broke into small icy shards.
"Hooray! We did it! We have slain this beast!" Sally cheered.
"No." Smarts replied with a frown, "we've just inconvenienced him. Ice fiends can put themselves back together, even if they're only reduced to ice cubes."
"That just means we have to melt him." Sally picked up the quill and scribbled a crude picture of a fire on the paper.
"Sally," Smarts retorted, "a physical item I can understand, but there's no way in Equestria that that feather can produce a fireball." And just as he said those words, a searing ball of fire erupted from the paper, in the direction of what it was pointed at: The ice fiend. At this point, Book Smarts throws all of his logic out the window in terms of the phoenix feather. The small shards of ice didn't stand a chance against the intense heat, and they quickly melted into a dark purple puddle.
"Well, mortals," they heard the puddle retort, "you have succeeded in defeating me, a foot soldier, nothing more, nothing less. More soldiers shall come, in greater numbers, and in greater ferocity. Ponyville will be razed to the ground. If you truly wish to throw away your lives and try to stop us, come to Razorback Ridge. Our base is set up there." And with those last words, the purple puddle soaked itself into the dry earth.
All at once, dark clouds encircled the sky. "Come on, Smarts, we have to find their base."
"What?" Smarts replied incredulously, "Are you insane? We're going to get killed! Tortured!"
"Smarts, if we don't, they're not gonna stop. Monsters will flood in like a wave that never wanes. Even the heroes are gonna get tired. Ponyville is going to fall, and everyone inside of it as well."
"Sally! Open your eyes! This is the real world! There are no more heroes left!"
"Oh, yes there are." Smarts and Sally turn around, and see a purple unicorn trot up to them. "You two need to go to Razorback Ridge and try to stop this. Me and the girls are gonna take care of this."
"And who are you supposed to be, exactly?" Smarts replied with sharp venom in his voice.
"My name is Twilight Sparkle." The unicorn said, "I'm the residential librarian here in Ponyville. You two need to get out of here."
"Oh, you've got to be kidding me." Smarts lets out a sarcastic laugh. "You? A hero? Like in the legends? Ha! Like I'll ever believe something so foolhardy." But just as he said that, another three ice fiends materialized to the right of Smarts, only to be instantly shattered and melted by a powerful magical fire with an amethyst hue. He quickly turned back to the librarian, whose eyes had just stopped glowing an ominous white. "… you have my blessings." Smarts said quickly, hoping he didn't offend the powerful unicorn in any way.
