Transmigrated into another world with the strongest core

Chapter 4: The Weight of Aether

The classroom was immense, with high arched ceilings and walls lined with ancient runes that pulsed faintly, as if attuned to the thoughts of the students. Long wooden benches stretched across the room, each engraved with subtle patterns that hummed softly when touched. Lucas followed Elara to a seat near the front, his eyes scanning the room in awe.

At the head of the class stood the professor, a tall man with grey hair and a commanding presence. He adjusted his glasses and surveyed the students before speaking.

"Good morning, class. I'm Professor Alaric Dorne. Today, we begin with the foundation of all magic: Aether," he announced, his voice carrying easily through the hall. "Aether is the lifeblood of our world. It is energy, yes, but it is more than that. It is intent, will, and essence intertwined. It exists in every living being, in the air, in the ground, and in objects that have been touched by magic. To manipulate it is to interact with the very fabric of reality."

He paused, letting the weight of his words settle. "Every spell you cast, every effect you produce, comes from the careful drawing, shaping, and releasing of Aether. The process is precise. Draw it from your internal reserve or the environment, shape it with intent, and project it outward. Fail at any step, and the result can be unpredictable."

Lucas shifted in his seat, feeling a subtle pressure in his chest just from hearing the explanation.

The professor continued, pointing to a series of glowing symbols etched into the blackboard. "Aether is organized into tiers, reflecting your capacity to hold and control it. Beginners are Novices; they can feel it and manipulate small amounts. Adepts, like some of you here, can sustain moderate flows and produce basic spells. Experts can shape large amounts, Masters can bend it in sophisticated ways, and Ascendants are extremely rare. They can reshape the environment, affect life itself, and leave a mark on history."

He tapped a symbol on the board, and it glowed brighter. "Within each tier, there are spell types: elemental, defensive, enhancement, and utility. Elemental spells manipulate raw energy: fire, water, wind, earth. Defensive spells form barriers or shields. Enhancement spells bolster your body or weapons. Utility spells encompass everything else: communication, detection, healing, and other effects that do not directly damage or defend."

Lucas’s mind raced. "So, every spell fits into a tier and a type…" he muttered silently, trying to process the structured system.

The professor’s gaze swept the room. "Finally, understand the Aether Core. It is the central point within your body where your personal Aether concentrates. Its stability determines your control. Beginners struggle to maintain it; experts barely notice its flow. A disturbance in the Core can cause spells to misfire, Aether to rebel, or, in extreme cases, permanent damage."

He leaned on his staff, voice lowering slightly. "Magic is not freedom. It is responsibility. Each spell draws from your life, your will, and your understanding. Respect it, study it, or it will teach you harsh lessons."

Lucas leaned back, absorbing every word. He had never realized how structured and disciplined magic truly was. It wasn’t just power; it was weight, responsibility, and precise technique. And somehow, he already felt that his connection to Aether was different, though he did not yet understand why.

The professor straightened, tapping the air with his staff. The runes on the board shimmered, displaying a grid of symbols.

"Let us begin with the Novice tier," he said. "At this level, you can sense Aether, draw small amounts, and cast basic spells. Elemental spells might include sparks of fire, small gusts of wind, or minor water currents. Defensive spells are limited to simple barriers that can hold back minor attacks. Enhancement spells may allow slight increases in strength or speed. Utility spells can illuminate a dark space or slightly mend a broken object."

He paused, letting the students take notes. "Control at this stage is fragile. Your Aether Core is still young, unstable. Misjudging the flow can exhaust you or cause the spell to misfire."

The professor’s gaze shifted toward the front rows, lingering for a moment on Lucas. "Next, Adept tier. This is where most of you stand or will stand within weeks. Adepts can sustain moderate flows of Aether. Elemental spells can manifest as controlled flames, gusts that knock back opponents, or streams of water that can be shaped with precision. Defensive spells form barriers that can withstand multiple strikes. Enhancement spells can significantly boost your agility, strength, or resilience. Utility spells broaden: detection of Aether, communication over long distances, minor healing."

He waved his staff, and a small flame hovered above it, dancing without flickering. "Notice the balance. Adept-level spells require focus, but they allow real influence over the environment. If your Aether Core wavers here, even slightly, the spell will falter. The weight of Aether becomes noticeable, and your body feels the flow pushing against your intent."

He tapped the board again, and the Adept column glowed. "Expert tier. Here, you are manipulating Aether at a scale that strains both body and mind. Elemental spells may summon walls of fire, controlled lightning, or torrents of water. Defensive spells can absorb multiple, strong attacks. Enhancement spells allow sustained physical superiority. Utility spells now include complex enchantments, teleportation of small objects, or advanced healing."

Lucas swallowed. He could already imagine how heavy the Aether would feel at this level; he had felt it slightly during the brief encounter with Grimlings.

"Master tier is rarer," the professor continued. "Only a few achieve it. Masters can shape vast quantities of Aether, combining types or creating effects that last minutes, hours, even days. Their Elemental spells reshape terrain; their Defensive spells protect entire areas. Enhancement can elevate them beyond normal human capacity for extended periods. Utility magic becomes highly specialized, creating constructs, controlling weather locally, or performing powerful soul-level healing."

The board shimmered as he highlighted the Master column. "And finally, Ascendants. Legends. Practically beyond comprehension. Their Aether bends reality, their intent shapes worlds. Most of you will never reach this tier, and those who do are often subjects of study rather than instruction."

He let the room absorb the information, then turned to a new symbol that floated above the board. "Now, let us talk about casting. As I mentioned, every spell has three stages: draw, shape, and release. Draw Aether into your Core. Shape it according to the type of spell and its tier. Release it with intent. The Core is your anchor. Disturb it, and even a simple Novice spell can fail catastrophically."

He let the words hang. "Each spell type elemental, defensive, enhancement, utility demands a slightly different approach to shaping the Aether. Elemental spells require flow and aggression. Defensive spells require stability and tension. Enhancement spells require attunement to the body. Utility spells require finesse and clarity. The higher the tier, the greater the precision needed."

Lucas felt the weight of it in his chest, as though the words themselves pressed against him. The theory was precise, structured, absolute. Magic was not instinct alone; it was control, discipline, and understanding.

"And remember," the professor said, lowering his voice so that only a few could hear, "some of you may feel that Aether resists you. That is not failure. That is awakening. Some souls respond differently. Pay attention, learn its rhythm, or it will punish recklessness."

He stepped back, letting the lecture settle. "That is the foundation. Understand it well. Next week, we begin applying this knowledge. Until then, study the tiers, the spell types, and the nature of your Core. Your body and mind must prepare for the weight of Aether."

Lucas sat back in his seat, absorbing every word. He could already feel the presence of Aether in the room, subtle but insistent, pressing against him, waiting for his intent. Somehow, he knew it would not be easy.

"Lucas, Lucas," a voice called. He looked up. It was a tall boy with black flowing hair. He looked majestic, like a Greek statue. "I've been worried. Where have you been? You haven't been to the room since yesterday."

"Oh, sorry to make you worried," Lucas replied with a smile, thinking this must be his roommate. "I've been training with Elara."

"Good morning, Gerald," another boy said, this one with grey hair, greeting Lucas’s roommate.

"Good morning, Roderic. Look who I found here," Gerald replied, pointing to Lucas with a smile.

"See, I told you not to worry about him. He's probably with his girl coughs oh, sorry, his friend," Roderic said while laughing. Gerald also burst into laughter.

Lucas looked at them and thought his friends seemed lively and funny. Unknowingly, he joined in their laughter.

"Can you guys stop?" Elera said with a serious expression.

"Sorry, sorry, our queen," Roderic said with a smile.

"We didn't mean to offend your highness," Gerald added sarcastically.

"You guys are so annoying," Elera replied, still looking angry. "Anyway, have any of you seen Mira? We need to talk about something all of us about Lucas."

"Yeah, we haven't seen her today. We thought she would be with you and Lucas," Gerald replied, looking worried.

"Now that you say it, Lucas has been a little too quiet. What's wrong with him?" Roderic said, also visibly concerned.

"Guys, it's nothing much. I just hit my head," I said while putting on a fake smile. "Instead, let's look for Mira. She might have gotten into trouble or something."

"Lucas is right. I have a bad feeling about this. She might have gotten into trouble," Elera replied. "Roderic, can you use your Detective Sight ability to find out where she was last?"

"You do know I haven't mastered it yet, and the teacher said I might lose my eyesight if I strain it too much. But I'll try," Roderic replied.

"Okay, let's go to the club room and try this there. I'll share some of my Aether mana with Roderic since I'm the one with the most here," Elera said, still with a serious expression.

They all stood up and started walking toward their club room, and Lucas thought: Club room? What kind of club is this, and who is Mira? These are my friends; I need to know more about them. Maybe I'll get more answers in the club room, but for now, I have to play along.
