The history classroom was nothing like the training yard.
It was a wide, high-ceilinged room on the third floor of the main academy building, lined with tall windows that let in long rectangles of afternoon light. Maps covered three of the four walls — detailed and hand-illustrated, showing the continents of Velstra in careful ink, with annotations marking mountain ranges, beast territories, and the locations of the great origin sites. The room smelled of chalk and old wood, and the benches were arranged in tiered rows that curved gently toward the front.
Raven, fifteen and in his first year, sat near the middle of the room, already watching the front with the particular stillness he reserved for things he found genuinely interesting.
Their instructor was a broad-shouldered man named Aldric — somewhere in his mid-fifties, with a neatly trimmed grey beard, deep-set brown eyes that carried the weight of someone who had seen real conflict, and the unhurried manner of a man who had told this story many times and still meant every word of it. A long faded scar ran from his left jaw down to his collar, half-hidden beneath his beard. He wore the academy's standard dark instructor uniform, but carried himself like someone who had spent far more years outdoors than in a classroom.
He set down his chalk and turned to face the class.
"Three hundred years ago," he said, "the world was different."
He let that sit for a moment before continuing.
"Velstra existed much as it does now, in its geography and its shape. The same mountains, the same rivers, the same sky. People farmed, traded, built cities, argued over borders. In almost every way that mattered, it resembled the kind of world you might find anywhere." He paused. "And then, on a morning that no one who lived through it ever forgot, the Origin System spoke."
A hand went up near the back of the room. A boy named Corvin — lanky, with messy auburn hair that never quite sat flat and an expressive face that made it impossible to tell whether he was being serious or not — raised his hand with the enthusiasm of someone who had been waiting to ask since before the lesson started.
"Spoke how?" Corvin asked. "Like a voice?"
"Like a notification," Aldric said. "Every living person on Velstra received it simultaneously. It appeared before their eyes regardless of where they were, what they were doing, or whether they were asleep or awake. A single message, seen by all, in the same instant."
He turned and wrote on the board behind him in large letters:
EVOLUTION INITIALIZED.
"That was all it said. No explanation. No instruction. No warning of what was coming next."
A girl near the front leaned forward. Her name was Sela — small and sharp-eyed, with close-cropped dark hair and the kind of focused expression that made her look perpetually one step ahead of everyone around her. She was quiet in most of her classes, but in this one she always had something to say.
"What did come next?" she asked.
Aldric's expression was steady, but there was something in his eyes that suggested the answer deserved to be delivered carefully.
"Everything changed," he said. "Within hours, the beasts began."
He moved to the nearest map and placed his hand over the great central forest of Velstra, an expanse that took up nearly a third of the continent.
"Animals that had been ordinary — birds, wolves, deer, creatures people had lived beside for generations — began to evolve. Rapidly, and without warning. They grew larger. Stronger. Some developed abilities that had no natural explanation. They became what we now call beasts, and in the early days of the evolution, they were not calm about it."
"They attacked?" Raven asked. His voice was quiet but it carried.
"They raged," Aldric said. "We believe the evolution was painful for them, disorienting, and in that disorientation they became dangerous in a way the world had never seen. Cities near the forests were struck first. Settlements at the edges of beast territories were overwhelmed. The conventional weapons of the time did almost nothing."
The room had gone very still.
"What saved them?" Raven asked.
Aldric looked at him for a moment, then gave a small nod, as though the question was exactly the right one.
"The summoned," he said. "In the early days of the evolution, certain individuals vanished. Simply disappeared — from their homes, their fields, the middle of conversations. They were gone for hours, sometimes days. When they returned, they were different." He tapped the side of his temple. "They came back with origin abilities. Powers unique to each individual, drawn from something deeper than training or talent. And those abilities were the only thing capable of standing against what the beasts had become."
Corvin's hand shot up again before Aldric had finished. "Why them? Why those specific people?"
"That," Aldric said, "is a question three hundred years of scholarship has not fully answered. What we know is that the Origin System chose them, in the same way it has continued to choose, generation after generation, ever since." He clasped his hands behind his back and faced the class. "Which brings us to something all of you will need to understand clearly before the trial."
He paused, letting the weight of the word settle.
"Origin abilities are ranked from D to SSS. That rank represents your potential — the ceiling of what you are capable of becoming. It is assessed at the trial and it does not change. You cannot train your way to a higher rank. You are born with what you are born with." His voice was matter-of-fact rather than cruel. "However."
He held up a finger.
"Tier is different. Tier measures your current strength — where you stand right now. There are seven known tiers, and unlike your rank, tier can be raised. Through training, through battle, through experience. Your rank tells the world what you could become. Your tier tells the world what you are." He looked across the room slowly. "Until the trial, none of you carry a tier designation. You are unranked. You train with your weapons, you develop your bodies and your discipline, and you wait."
"What about beasts?" Sela asked. "Do they have ranks too?"
"Beasts have tiers," Aldric said, "the same seven that apply to humans. But their classification system is its own. Rather than letters, we categorize them by rarity — common, uncommon, rare, epic, and legendary. A legendary beast and a human of high tier and high rank would make for a very dangerous encounter." He said it plainly, without drama. "I mention this not to frighten you, but because you will encounter beasts. All of you will. And when you do, knowing what you are looking at may be the difference between a good decision and a fatal one."
The room was quiet for a moment.
Then Corvin raised his hand again.
Aldric looked at him with the patient expression of a man who had long since made peace with the fact that some students simply could not stop asking questions.
"Yes, Corvin."
"Has anyone ever been ranked SSS?"
Aldric was quiet for just a beat longer than usual.
"Not in recorded history," he said. "No."
He turned back to the board, and the lesson continued. Raven stared at the maps on the wall long after the others had looked away, his amber eyes tracing the beast territories marked in red ink, thinking about a world that had changed overnight once before.
He wondered, quietly, if it could happen again.
