"When Day becomes Night… what in Equestria does that mean?" thought a bewildered Twilight. "I just hope I have enough time to figure out this riddle!" Just as Twilight landed in Ponyvile, a large explosion was heard in the direction of Sugarcube Corner. Usually, Twilight knew that Pinkie was behind this; a bad cupcake mixture gone wrong, but this time was different. She flew all the way to Sugarcube Corner where her student, Baron Blaze, was coughing.
"Are you alright Baron?!" cried Twilight "Where are my friends?!"
"Chill down Twilight! Nopony is hurt!" assured Baron "Pinkie added way to much ammonium nitrate, causing his "small" explosion."
Twilight finally calmed down, realizing the threat that Celestia spoke of was not here. She quickly went inside the kitchen where large amounts of cupcake mix covered everything and every pony.
"Is every pony alright?" asked a concerned Twilight.
"Well if you count the stove, that make'ems a causality" said Applejack.
"Oh yuck! It's going to take hours to remove this mix from my hair!" cried Rarity "Good thing I didn't bring my good dress for this occasion."
"Still! This mix is pretty delicious!" said Pinkie, as she licked off the mix from her body in one swoop of her tongue."
As the mane six left to shower themselves, Baron left with his teacher back to the library. Baron could easily tell that something was troubling her.
"What's wrong Twilight?" asked Baron.
"It's nothing" replied Twilight.
"It's something alright" cried Baron, "You were freaking out when I saw you at Sugarcube Corner, usually you would say something like 'What did Pinkie make this time?', but you didn't; you thought a REAL explosion happened huh?
"Look Baron, it's getting late" said Twilight, completely ignoring Baron's previous explanation, "Go home, I'll explain everything tomorrow; right now I have to study by myself and I can't be interrupted for the rest of the day.
With that, Twilight flew away from her student to her residence. As Baron came to his residence, a cottage, he took a deep breath, cleaned his hooves on a mat that said "welcome", he entered. As he entered the cottage, he was greeted with pictures of himself and his marefriend, covered all over the cottage. As he closed the door, a familiar voice emanated from a room.
"Baron honey, is that you?" said the voice.
"Yes Marnie honey, it's me" replied Baron.
"You're here quite early" she said, "Is everything okay?"
"Nothing bad, just a really weird day" replied Baron.
As Baron entered the room, he saw his beautiful marefriend, bedridden and the familiar machines that kept her alive.
"How are you doing babe?" asked Baron.
"Well when you're suffering from leukemia everyday for the last six months, you aren't doing so well" answered Marnie "But I'm trying".
"I didn't mean it like that."
"I know Baron, so how was your day with Princess Twilight?"
Just as Baron was about to tell her his day involving Pinkie's mishap, the machine made a loud beep.
"I'm sorry Marnie, maybe tomorrow, you have to take your medicine and you know how strong this type of medicine is" said Baron.
"I guess it can't be helped. I'll see you tomorrow morning then."
As Baron injected the medicine, Marnie slowly began to close her eyes. Realizing that the full moon was shining brightly, he decided to go to sleep too. He quickly showered, brushed his teeth, flossed and made his way to bed. "If only I knew stronger magic" he thought to himself, "I could've cured her long ago! I wish I was a stronger unicorn". With that wish, he quickly drifted to his dreams.
"So you want Power? Is that what your heart desires so?" said a mysterious voice.
"Who are you?! What do you want?" yelled a bewildered Baron.
Suddenly, Baron what transported to a burning town; the streets ran red, with the blood of hundreds. Many of its citizens were running in fear, while some were being burnt alive and others were being incinerated by a tall and dark figure. He then spotted a weak mare being trampled by ponies too afraid to care, near the figure. Without thinking, he quickly teleported to her, only to realize it was Marnie, dead from a knife wound to the heart.
"NO! Marnie! Don't leave me!" cried a sobbing Baron.
As the dark figure was about to incinerate him with his magic, Baron awoke in a morning sweat, only to realize it was morning.
