Isaac only realized the ambient sound of the city had completely vanished when he consciously tried to hear it again.
Before, there had been persistent background noise—footsteps echoing off stone, distant voices carrying through narrow streets, the occasional rhythmic creak of merchant carts rolling over uneven cobblestones. A constant, layered soundtrack that had become almost comforting in its familiarity. Now—nothing. Only the irregular crackling of the oil lamp hanging from the ceiling and his own breathing, noticeably heavier than it should have been.
He frowned, immediately alert to the wrongness.
Maybe it had been the door closing, sealing out external sound. Maybe it was accumulated exhaustion affecting his perception. Since returning from death, the boundaries between one moment and the next were no longer clearly defined. Things didn't transition smoothly anymore—they simply changed state abruptly, like pages torn from a book.
Melissa didn't seem to notice the silence. Or she noticed and deliberately didn't care.
She stood beside the worn table, both hands resting flat on the aged wood, eyes lowered as if carefully arranging complex thoughts before saying something that absolutely couldn't be misunderstood. When she finally raised her gaze, it was too direct and penetrating to be casual observation.
"Do you still remember what I explained to you before?" she asked. "About magic. About the routes practitioners can follow."
Isaac took a moment to answer honestly. The memories came in disconnected fragments, like nearly everything since his impossible return.
"I remember you mentioned seven routes," he said finally. "Specific paths that mages choose to follow." He hesitated, searching his fractured recollection. "But the actual details... weren't clear. Still aren't."
Melissa nodded, completely unsurprised by this admission.
"Doesn't matter. We'll start from the absolute beginning, then." She straightened her posture and crossed her arms in what appeared to be a relaxed stance. "But pay genuine attention this time. I won't repeat myself three times like some patient academy instructor."
Isaac adjusted himself in the chair, trying to find a more comfortable position. The wood creaked beneath his weight—louder than it should have been in the profound silence filling the room.
"First thing," Melissa said, "and the most fundamentally important principle you need to understand: magic is exchange. Always. No exceptions whatsoever."
She let the words settle deliberately in the heavy air. There was no dramatic emphasis or theatrical pause, which somehow made the statement more ominous.
"No matter which route you eventually choose. No matter how powerful you become through practice and sacrifice. There is always a cost that must be paid."
Isaac felt a slight tightening sensation in his stomach, something cold and uncomfortable.
"A cost like ritual sacrifice?" he asked cautiously. "Blood offerings, that kind of thing?"
"Sometimes," Melissa acknowledged, tilting her head slightly. "But that's the simplistic, superficial way of looking at it. The real cost is rarely that direct or obvious."
She absently pushed a loose strand of dark hair behind her ear. The gesture immediately failed—the hair fell back almost instantly, framing her face again.
"It can be time you lose without consciously noticing it slipping away. Memories that start to blur at the edges, becoming uncertain. Pieces of who you used to be, fundamental aspects of your personality, just... eroding."
The oil lamp flickered unstably, casting dancing shadows across her angular features.
"We call it equivalence," she continued with clinical precision. "Not because the exchange is fair or just. But because it's inevitable and inescapable. You want to produce a large effect, you pay a correspondingly large price. You want something smaller or more modest, you pay proportionally less. But you always, always pay."
Isaac thought of the entity from the Deep Darkness. Of that terrible feeling that it didn't just threaten his physical body, but something far more fundamental—something that none of these carefully chosen words quite reached or described.
"The worst part," Melissa added, lowering her voice slightly, "is that the price rarely shows up immediately. You cast the spell, achieve what you wanted, and genuinely think you got off remarkably cheap."
She gestured vaguely at the empty air.
"The cost comes later. Sometimes much, much later."
Isaac nodded slowly, absorbing this.
"I understand."
"Good." Melissa stepped away from the table and began pacing the room with measured steps. Her footsteps were nearly silent against the floor—an old habit of someone who'd learned to move without being noticed. "Now, the routes themselves. There are seven major paths. Every mage who survives long enough to develop real power ends up choosing one."
"Why?" Isaac asked. "Why not follow more than one simultaneously? Wouldn't that make you more versatile?"
She answered without any hesitation.
"Because you die. Or something worse than death happens."
She stopped pacing and turned to face him directly.
"Each route pulls you in a fundamentally different direction. Tries to shape you, remake you, in a very specific way. Trying to follow two at the same time is like trying to walk north and south simultaneously. You can manage for a few steps, maybe even convince yourself it's working. Then you tear yourself apart from the inside."
Isaac swallowed hard.
"Each route is born from a sin," Melissa continued, raising one hand before he could react with visible alarm. "Not in the shallow, conventional religious sense. I'm not talking about divine condemnation or theological judgment."
Her tone remained clinical and detached.
"I'm talking about fundamental human impulses. Distortions of natural drives that, when consciously fed and cultivated, respond with tangible power."
She raised one finger deliberately.
"Greed."
"It's the most common starting point among beginners," she explained. "Because it seems perfectly rational on the surface. Why laboriously create something from absolute scratch when you can simply copy what already exists?"
She resumed her measured pacing.
"Greed practitioners observe carefully, duplicate what they see, combine existing elements. They witness a useful power and immediately try to replicate its effects. They find an ancient artifact and methodically dismantle it until they understand how to reproduce what it does. Sometimes..." She paused meaningfully. "They tear abilities directly out of other living mages."
"That doesn't sound inherently evil," Isaac said cautiously, testing his understanding.
"It doesn't," she agreed readily. "At first, anyway."
She stopped walking again, fixing him with her dark eyes.
"The cost is psychological before it becomes physical. The practitioner never feels complete or satisfied. There's always something missing from their collection. Always another power they should have acquired, another technique they need to master."
Her gaze hardened noticeably.
"Eventually, other people stop being people entirely. They become potential resources. Walking repositories of abilities to be catalogued and harvested. The ethical line between 'copying through observation' and 'stealing by force' completely disappears."
Isaac felt distinct discomfort crawl through his gut, shifting like something alive and writhing.
"Wrath," Melissa continued, lifting a second finger. "This one's considerably more honest about what it is."
She clenched her fist experimentally, testing the tension in her own muscles.
"Raw combat prowess. Physical strength. Endurance beyond normal limits. Power grows directly through conflict and violence. The more intense the battle, the stronger the practitioner becomes afterward."
"So they have to fight constantly?" Isaac asked.
"They need war," she corrected firmly. "Or at minimum, they need to maintain the mindset of someone at war. Always."
She looked straight at him without blinking.
"Wrath adepts become living weapons. They keep fighting when any normal person would have already collapsed from their wounds. Broken bones stop mattering. Pain becomes background noise."
Isaac thought of certain soldiers he'd known. Men who could never truly stop, even in peacetime.
"The cost," Melissa said, "is that eventually they stop fighting because circumstances require it." A brief, significant pause. "And start fighting because violence is the only thing that still makes coherent sense to them."
Isaac took a deliberately deep breath before she continued.
"Lust."
Her tone cooled noticeably.
"It's not seduction or physical desire," she said before he could form the obvious question. "It's dominance. Making others want what you want them to want. Shaping wills. Rewriting the desires of others to align with your purposes."
She looked away for a moment, as if the explanation itself was uncomfortable.
"The cost is empathy. The more people you control, the less real they seem. Even genuine intimacy becomes just another tool, another means to an end."
A distinct chill ran through Isaac, and he had to shift position in his seat.
"Sloth," Melissa said next, and something subtle changed in her voice—became more carefully restrained.
"It's the most fundamentally misunderstood route."
"Why?" Isaac asked.
"Because it's not inertia or laziness. It's absolute, ruthless efficiency."
She gestured slowly, deliberately.
"Sloth practitioners don't directly confront problems. They make problems wait. They create zones where effort loses all meaning. Where the world itself drags and slows."
"Time manipulation?" Isaac asked.
"On relatively small scales," she confirmed. "Delay. Slow down. Make a sword feel too heavy to effectively cut. Make a pursuer tire without understanding why their strength is failing."
She fell silent—too long, as if remembering something personal.
"The cost is progressive disconnection," she said at last. "The world starts to feel... slow. Irritatingly, unbearably slow."
Isaac realized he'd been unconsciously holding his breath and forced himself to exhale.
"Gluttony," Melissa continued, no longer bothering to hide her genuine disgust.
"Consumption. Devouring flesh, memory, essence itself."
She didn't elaborate further—she clearly didn't need to.
"The practitioner becomes hunger personified. Everything consumed only sharpens the appetite for more."
Isaac felt genuine nausea rise and had to brace one hand against the table for stability.
"Envy," she said after a necessary pause to let that sink in. "Imitation and replacement."
She tilted her head thoughtfully.
"Envy practitioners don't simply want what you have. They want to be you. They steal your appearance, your voice, your relationships, your position in the world. Eventually even the people around you forget who you actually were."
"And the cost?" Isaac asked.
"Identity," she answered softly. "After wearing so many masks, stealing so many lives, there's no original face left underneath."
The silence stretched uncomfortably.
"Pride," Melissa said finally, and her tone became even more careful.
She chose each word with visible precision.
"Growth. Authority. Presence that commands reality itself."
"That sounds—" Isaac began.
"Dangerous," she finished for him. "Because the fuel doesn't come from within the practitioner."
She met his gaze directly.
"It comes from belief. From others believing in you."
The chill was immediate and profound.
"The more people believe in you, trust you, follow you—the stronger you become. Your power is literally sustained by faith."
Unbidden, Isaac thought of the entity that had watched him from the Deep Darkness. And something fundamental unsettled him: it hadn't seemed to depend on belief at all. It had simply existed, regardless of whether anyone acknowledged it.
"And when that belief breaks?" he asked quietly. "When people stop believing?"
Melissa didn't smile.
"The collapse is proportional to how high you'd climbed."
Heavy silence fell between them.
After a long moment, Isaac asked:
"And you? Which route?"
Melissa took her time responding, as if deciding how much to reveal.
"Sloth," she said at last.
Isaac looked around the deliberately unremarkable room with new understanding.
"The house," he murmured. "The way everything feels... deliberately ordinary and forgettable."
"Exactly," she confirmed. "Maximum efficiency. Minimum effort. Why waste energy on appearances when that energy could be conserved?"
She leaned back against the table.
"And yes. I feel the cost accumulating. Every single day."
She looked at him directly.
"That's why you matter to me, Isaac. Because recognizing that you were worth the effort of genuine attention required me to overcome my natural tendency toward complete apathy."
The oil lamp flickered uncertainly.
And Isaac understood, with a cold sensation spreading down his spine, that this wasn't generosity or friendship.
It was calculated investment.
And somehow, that realization was more frightening than any of the seven terrible routes she'd just described.
Because it meant she saw potential in him worth the cost of caring.
And he had absolutely no idea what she expected that investment to eventually produce.
