Rain tapped against the tall glass windows of Ravencrest University's engineering building, the sound soft but persistent enough to pull at Cassian Vale's concentration. The campus was quiet at this hour. Most students had long since returned to their dorms or apartments, leaving the library and late-night study rooms to a handful of exhausted stragglers chasing deadlines and grades.
Cassian leaned back in his chair and rubbed his eyes. His laptop screen glowed with a half-finished simulation model that refused to cooperate. Numbers and formulas blurred together in his vision, and the coffee beside him had long since gone cold.
"Of course it won't stabilize," he muttered under his breath. "Because why would anything behave logically tonight?"
Across the study room, the last remaining student packed up their bag and left, the door clicking shut behind them. The quiet that followed felt heavier than before, as if the building itself had decided to hold its breath.
Cassian sighed and closed his laptop halfway. The digital clock on the wall read 11:47 PM. He should have gone back to the dorm an hour ago, but stubbornness had always been one of his less practical traits.
Outside the window, Ravencrest City stretched toward the dark horizon. Towers of glass and steel reflected the city lights, traffic flowed across distant bridges, and the harbor cranes stood like giant skeletons against the cloudy sky. Millions of people lived their lives out there every day, each convinced that tomorrow would look roughly the same as today.
Cassian stared at the skyline for a moment longer before something strange caught his attention.
The clouds above the city were glowing.
At first he thought it was lightning. A faint shimmer rolled across the sky, like distant heat waves bending the air. But the glow didn't fade.
Instead, it grew brighter.
Cassian straightened slowly in his chair, eyes narrowing as the strange light spread across the clouds in branching lines. They looked almost like cracks in glass.
"Okay," he said quietly to the empty room. "That's… not normal."
The light intensified.
Across the entire sky above Ravencrest, the clouds began to split apart as if something immense pressed against the other side of reality. Thin fractures of blinding blue energy spread outward, illuminating the city in pulses of unnatural light.
Cassian pushed his chair back and walked to the window.
Students were gathering outside on the campus lawns, pointing at the sky. Cars on the nearby streets slowed as drivers leaned out their windows to stare upward.
Then the sky broke.
There was no explosion, no thunderclap. The fractures simply widened until the entire night sky resembled shattered glass, and through those cracks poured something that no one on Earth had ever seen before.
Light.
Not ordinary light, but a deep, luminous energy that cascaded downward like an invisible tide.
Cassian felt it before he understood what was happening.
A pressure slammed into his body.
His knees buckled as an overwhelming wave of energy passed through him, flooding every nerve and muscle with unbearable heat. It felt as if his veins had been filled with molten metal.
All around the campus people screamed.
Some collapsed instantly, their bodies unable to withstand the sudden surge. Others clutched their heads or chests as the invisible force pressed down on them.
Cassian dropped to one knee beside the window, gripping the edge of a desk to keep himself from falling completely.
"What… is this?" he gasped.
The pressure intensified.
His heart pounded wildly, each beat sending jolts of pain through his chest. His vision blurred as strange sensations spread across his skin, like electricity dancing along his nerves.
For a terrifying moment Cassian thought he was dying.
He had read about strokes, aneurysms, and sudden heart failure before. The symptoms felt terrifyingly close.
But something inside him refused to give up.
Cassian gritted his teeth and forced himself to breathe slowly despite the agony surging through his body.
Think.
Panic would not help him survive whatever was happening.
He focused on the sensation itself. The pressure was painful, yes, but it was also strangely structured. The energy coursing through him didn't feel random.
It felt like something was… changing him.
Outside, sirens began echoing across the city. Some buildings flickered as power grids failed, plunging entire districts into darkness.
The glowing energy continued pouring from the fractured sky.
Cassian's hands trembled as he pushed himself upright again. The pain was still there, but it had begun to settle into a dull burn instead of the overwhelming wave that had nearly knocked him unconscious.
His reflection in the window looked pale and shaken.
Then something appeared in front of his eyes.
At first he thought it was a hallucination caused by stress.
A faint translucent panel hovered in the air, filled with unfamiliar symbols that quickly rearranged themselves into readable text.
Cassian blinked.
The panel remained.
[Scanning lifeform…]
The voice that accompanied the message wasn't truly audible. It resonated directly inside his mind, calm and emotionless.
Cassian froze.
"Okay," he whispered. "Now I'm definitely hallucinating."
The text shifted.
[Lifeform identified.]
[Species: Human.]
[Planetary designation confirmed: Terra.]
Cassian stared at the floating interface. He waved a hand through it experimentally, half expecting the projection to vanish.
His hand passed straight through the glowing panel.
The message continued updating.
[First Mana Wave successfully integrated.]
[Biological compatibility being evaluated.]
A cold shiver ran down Cassian's spine.
Mana.
The word was ridiculous. It belonged in fantasy novels and video games, not real life.
Yet the energy he had felt moments earlier certainly didn't resemble anything science could explain.
[Compatibility threshold exceeded.]
[Subject has survived the First Mana Wave.]
[Initiating Awakening Protocol.]
Cassian exhaled slowly.
"Awakening," he repeated under his breath.
Across the campus more screams echoed as people outside noticed similar panels appearing in front of them. Some tried to touch the glowing text while others backed away in terror.
Whatever this system was, he wasn't the only one seeing it.
The panel shifted again.
[Congratulations.]
[You have awakened as an Evolver.]
Cassian leaned against the desk behind him.
"An Evolver," he said quietly. "That sounds… concerning."
The message continued.
[Terra has entered the Evolution Era.]
[All living organisms will now follow the Path of Evolution.]
The words lingered in the air for several seconds.
Cassian's mind raced as he tried to process the implications. If this system was telling the truth, then whatever had poured from the shattered sky wasn't just energy.
It had changed the entire planet.
A sudden crash outside snapped his attention back to the window.
In the courtyard below, a group of students had gathered around something near the edge of the grass.
Cassian leaned closer to the glass.
A stray dog that often wandered through campus had been lying near the benches earlier that evening. He recognized it immediately from the brown patches in its fur.
Except the animal looked… different.
The dog's body convulsed violently as it struggled to stand. Its muscles bulged beneath its skin, expanding at an unnatural rate. Bones shifted with audible cracks while the creature's jaw stretched wider than should have been physically possible.
One of the students took a cautious step toward it.
The dog lifted its head.
Its eyes glowed a deep crimson.
Cassian's stomach dropped.
The creature lunged forward with impossible speed, knocking the student to the ground before anyone could react. Screams erupted across the courtyard as people scattered in every direction.
Blood splattered across the pavement.
Cassian stared in horror as the once harmless animal tore into its victim like a starving predator.
Behind him the system panel flickered again.
[Warning.]
[Planetary lifeforms undergoing accelerated evolution.]
[Survival probability will depend on your ability to adapt.]
Cassian forced himself to look away from the horrific scene outside and focus on the interface.
The calm voice returned.
[Preparing initial system integration.]
[Stand by for class selection.]
Cassian let out a shaky breath.
The city beyond the campus was already descending into chaos, and if the system's message was accurate, that was only the beginning.
Outside the mutated creature lifted its bloodstained head and howled into the night.
Cassian Vale stood alone in the dim study room, staring at the glowing panel hovering before him as the world he had always known collapsed in real time.
Whatever came next would determine whether he survived Terra's new era.
Or died like so many others already had.
