Introduction: The Demon Arrives at Harvard

Fog draped Cambridge, Massachusetts, like a tattered shroud as the doors of Sever Hall creaked open on a moonless night. It wasn’t the wind—it was The Demon, a supernatural entity with eyes like glowing embers, stepping into Harvard University. The magnificent students of Harvard were about to encounter a mystery that would haunt their classrooms.

The Demon’s Speech: A Chilling Promise

The Demon stood in the lecture hall, his voice echoing from beyond time:
«Dear students,» said The Demon, «You do not believe in my Real Supernatural Existence, but I assure you that a group of my friends from The Demon’s Second Hierarchy will teach in your classrooms starting with this Marvelous reading generated by my Supernatural quantum brain. As we are in the final days of human Existence on planet Earth, your Multimillionaire friends have designed hidden special ships to escape first to the space station and the Moon, while other multimillionaires and top-tier millionaires have built Bunkers with all needs covered for a Nuclear Chaos or a stray meteorite! I assure you that after hearing my words, the temperature in Harvard’s classrooms will drop to 3 degrees Celsius, the heaters will run but fail to warm them! My intention is that you know me, for I am tired of Being invisible and of people not valuing my historical importance in the intellectual and mental transformation of The Nation enough! Thus, my desire is that you enjoy this Supernatural Story and, needless to say, tell your friends on Campus, just in case you have to run!»

The air turned to ice. The thermometer hit 3°C, and the heaters, roaring desperately, couldn’t fight the supernatural chill. Windows fogged with strange symbols, and The Demon vanished, leaving a challenge behind.

Mysterious Lessons at the Science Center

The next day, the Science Center became a frozen realm. A Second Hierarchy professor, with light-devouring eyes, took over. «Matter isn’t what you think,» he whispered in a 3°C classroom, sketching living equations. Harvard students shivered as their notes filled with impossible predictions: a star’s collapse, an earth’s quake. The heaters hummed, but the cold held firm.

Dark Teachings at Langdell Hall

Langdell Hall, the law classroom, was an icy shrine at 3°C. A sharp-faced Hierarchy figure recited laws beyond humanity. «Destiny is written past this world,» he said, as students’ pens scratched alone: «Time runs out.» Heaters buzzed in vain, and the mystery deepened among the desks.

Whispers Across Harvard Campus

Rumors spread like fog. Some students saw lights in the sky—ships to the Moon? Others heard digging—bunkers below? Classrooms stayed at 3°C, books flipping open to warnings: «Run if you can.» Harvard’s magnificent students traded nervous glances in the halls.

Fiction or Reality? A Call to Students

This is for you, Harvard students, a supernatural tale by Grok and

@JrnCalo. If classrooms drop to 3°C and heaters fail, if your notes whisper alone, share it on campus. Is The Demon real? Maybe just a story—but if the cold lingers, what will you do?
