The Mana Engineer

The Day the Sky Opened

2,673 words

The hum of the tires on the asphalt was steady and low—the kind of sound Eric only noticed when he was tired.

Today, he was tired. Not the muscle kind, but the kind that lived in his bones—long hours of solving other people’s problems in an office that never stopped generating them.

He glanced at the dashboard clock. 6:14 p.m.

Twenty minutes home, maybe twenty-five if traffic stacked up near the overpass.

He smiled despite himself. Home meant her. Home meant them.

He chuckled under his breath, fingers drumming the steering wheel as the orange wash of late sunlight slid across the windshield.

He could already picture her—curled on the couch, auburn hair tied in that lazy bun she always pretended didn’t take ten minutes to perfect. He thought about kissing her the second he walked through the door, how she’d roll her eyes and pretend to be annoyed while leaning into it anyway.

Fourteen years married, and he still thought about kissing her on the drive home.

That fact surprised him sometimes—not the affection, but its persistence.

His mind wandered further, sketching the evening ahead.

Eli, twelve, would be half-buried in a Minecraft world he’d been carving into digital art.

Heather, four, would barrel into him the moment the door opened—curls, giggles, and that shrieking DADDYYYY! that made every day better.

He laughed softly, imagining the two of them already arguing over snacks, and how she—Anna, ten years younger than him—would be sitting there with that perfectly contained chaos-mom expression: calm on the surface, one twitch from boiling over, somehow still graceful in the middle of it.

It was funny, in a way, how it had all begun. Fifteen years ago, he hadn’t been looking for her.

An online dating app.

She’d been younger than he meant to consider—honestly, he almost scrolled past her. But something in her profile had stopped him. Not clever in a rehearsed way, just smart. Witty. Alive.

So he messaged her.

An awkward, cautious, Hey, you seem interesting.

And somehow—fifteen years later—he was driving home to her, to their kids, to a life he wouldn’t trade for anything.

He sighed contentedly—the small, satisfied exhale of a man proud of what he’d built.

For a moment, he let himself settle into it.

Then the light came.

It started as a pinprick at the edge of his vision, sunlight flashing off chrome.

Then it grew—faster than his brain could process—expanding from a glimmer to a blinding flood that swallowed the dashboard, the windshield, the entire car in a heartbeat.

Eric jerked the wheel instinctively, but the world was already gone.

The hum of tires, the wheel beneath his hands, even the sense of motion—ripped away in one violent, impossible instant.

Silence.

Weightless.

Nowhere.

And because his brain handled shock badly, his first thought wasn’t panic. It was, What—where am I? Am I dead? Or… holy hell, am I getting isekai’d right now?

Everything was white—not darkness, as one might expect from being nowhere in space and time, but endless white.

A soft chime replaced his heartbeat. Then another. Then hundreds—cascading into one perfect crystalline tone that filled the void.

A floating screen unfolded before him, translucent glyphs etched in pale blue light.

[Initializing System Integration…]

[Evaluating Mana Compatibility…]

[Status: Non-native mortal. Adapting biology.]

[Conversion required. Rebuilding biology from soul-thread.]

Eric blinked. Oh. Oh, we’re doing this. This is… yeah, okay. Definitely isekai’d.

The panel rippled, scanning his soul like an MRI designed by a fantasy novelist.

[Affinity Detection…]

Primary Elemental Alignment: Lightning

— Composition: Air + Fire resonance pathways

— Complex Affinity Tier: RARE (3.2%)

Mana Core: Active.

Status: Compatible.

Lightning affinity. Rare tier.

If he could have blinked, he would have.

Lightning affinity and rare tier? What does that even mean?

Another panel appeared, broader this time, branching into hundreds of faint options. Most were grayed out, locked behind opaque runes, but a few flickered invitingly:

[CLASS SELECTION REQUIRED]

• Warrior — Physical dominance, enhanced vitality, direct combat.

• Ranger — Dexterity focus, distance precision, tracking.

• Mage — Manipulator of weave structures; mastery of raw mana.

• Rogue — Subtlety, tactics, improvisation.

• Healer — Weave reinforcement, restoration of soul-thread damage.

Recommendation: Mage — based on Lightning Affinity (Complex).

Eric stared for two whole seconds.

I mean… come on. Of course it’s Mage. Like I’m gonna go full Geralt when I’ve got lightning running through my veins.

Mage, he thought.

The panel chimed softly, shifting.

[SECONDARY PROFESSION UNLOCKED]

Choose a complementary discipline:

• Artificer — Fusion of magic and craft, creation of enchanted devices.

• Alchemist — Transmutation and synthesis of materials.

• Scholar — High-risk theories with unstable outcomes.

Recommendation: Artificer — based on neural profile.

Yeah, alright, System. You know me better than I know myself.

Artificer, he thought.

Another cascade of light washed through the void as the panel updated.

New data streamed down the screen like a waterfall.

Eric stared at the sheet a long moment, then nodded.

So… thirteen Intelligence, lightning powers, pocket dimension, and an OP crafting tree. Yeah. This is 100 percent an isekai. All I need now is a cute companion that turns into a dragon and I’m set.

The screen pulsed one final time.

[Body Reconstruction Complete]

[Synchronizing soul-thread…]

[Calibrating…]

[Welcome, Outworlder.]

The world unfolded beneath him—glowing lines twisting into geometry that made his stomach lurch.

And then… he fell.

The landing was not graceful.

One moment, Eric floated through impossible geometry—cascading streams of golden light and whirling constellations of symbols that felt like they’d been etched into the bones of reality. He didn’t recognize any of it, but some part of him knew the patterns were important.

The next moment, gravity remembered he existed.

“—Wait, wait, wait—!”

WHAAAM.

He hit stone so smooth it felt wet, chest-first, like a diver belly-flopping onto a mirror. Stars detonated behind his eyelids, and the air punched out of him in a pathetic oof. For several seconds he lay there groaning, cheek pressed to an unnaturally cool floor that thrummed faintly, as if it had a pulse.

Somewhere above him, a dozen voices inhaled together. Air hissed between teeth, robes shifted, benches creaked—small sounds, suddenly enormous in the hush.

“Ten out of ten portal entry,” Eric muttered into the floor. “Graceful. Dignified. Definitely the hero of this story.”

He pushed his palms under him, found his elbows, and blinked into the light.

He was inside a circle—not just chalk on stone, but a carved, glowing geometry of interlocking sigils and thin channels filled with something that looked like liquid glass. Around that circle, a dome had formed: a semi-transparent shell that rose in a perfect curve, gleaming like spun crystal. Its edge kissed the floor with a line of lambent runes, each glyph pulsing in time with a slow, steady heartbeat he felt more than heard.

He rapped the inside of the barrier with a knuckle. It rang—high and clean, like tapping a wineglass. Not glass, exactly. Something harder. Something alive.

“Okay,” he breathed. “Magic hamster ball. Noted.”

Outside the dome, ascending benches swept up in perfect arcs around the platform, each tier packed with robed students.

“Huh.. Elves,” Eric said “didn’t expect that.”

The sight would’ve been majestic if not for the absolute meltdown happening behind all those carefully schooled faces. Half the room was white with shock; the other half was red with embarrassment.

Then Eric noticed another detail.

They were all staring.

At him.

He glanced down.

No clothes.

Nothing.

He hurriedly sat cross-legged and covered himself with his hands. The dome magnified the humiliating sense of being on display. Reflections ghosted in the curved surface: a bald, maybe eighteen-year-old stared back at him. The shine on his scalp was frankly offensive.

He closed his eyes for a beat, inhaled through his nose, and lied to himself with conviction. “This is fine. Totally fine.” Then, quieter: “New rule: if I survive this, I’m talking to the manager.”

Movement rippled through the first rows. Most students tried very, very hard to look at anything but him. A dark-haired boy discovered a sudden religious devotion to his shoes. Two girls near the aisle locked eyes with their notebooks and didn’t blink. A bluish tinted silver haired girl risked a glance and then snapped her head away so fast Eric worried she’d get whiplash. Another student peeked over her sleeve, went pink to the ears, and used the sleeve as if it could erase what she’d just seen.

Eric sighed. “Yup. Cool. Naked bald guy in a hamster ball. Definitely didn’t dream about this scenario in high school.”

A stifled snort escaped from the back. Like a cracked pane, the room spidered with tiny, nervous chuckles that died as quickly as they started.

“By the Threads of Nysera,” a voice snapped from the dais beyond the circle, “what is that!?”

The language was sharp, musical, and not English at all. Eric understood it perfectly.

“Oh,” he said softly. “Magic subtitles.”

He raised an awkward hand. “Uh… hi. I come in peace. Pants, please.”

That was not, strictly speaking, what he heard himself say. The sounds rolling out of his mouth were fluid and vowel-rich. But the crowd reacted like he’d spoken plain. In fact, they reacted a little too much.

“His accent is… strange,” someone whispered.

“Harsh,” someone else corrected. “Clipped. Like he’s chewing the edges.”

“He sounds a bit like a serpent, sssss.”

“Is he slurring?” a third voice murmured, scandalized. “Or is that just how humans sound where he’s from?”

Eric blinked. “Perfect,” he muttered under his breath. “I sound like a drunk tourist in Space-Elf.”

Nervous laughter flickered again. A girl in the front row jammed her quill behind her ear and stared at the ceiling.

A figure cut across the field of vision, blue and gold and furious. The elf in layered robes had cheekbones sharp enough to cut parchment, silver hair pinned back with brutal precision, and the exact expression of a man who had, until forty seconds ago, believed the world made sense.

He carried a stub of chalk like a weapon and a thick manual splayed open in his other hand. Crumpled pages poked out like broken feathers.

“This is impossible,” the elf snapped, stalking the edge of the barrier as if circling a lion. “Tier-three bounded elemental only. That’s what the array is set for. There is no alignment pathway—none—that should yield a sapient vessel.”

One brave student raised a hand and immediately wished she hadn’t. “Um… Professor Seltherin? Then… where did he come from?”

Seltherin stopped. He flushed an angry, blotchy shade that clashed magnificently with his robes. “Your question presumes the presence of a where,” he said through his teeth. “We are, at present, attempting to establish whether what happened is even possible.”

He turned the full beam of his indignation on Eric. “You,” he said, pointing the chalk like a spear. “Boy. State your origin plane at once.”

Eric blinked. “Yeah, I’ve got… absolutely nothing for you.”

Seltherin’s jaw tightened so hard it looked like he might crack his teeth. “Do not play games with me. What world claims you?”

Eric hesitated, glanced down at his bare legs, and picked the hill he was willing to die on. “Whichever one wears pants.”

The room tried not to laugh. The room failed.

Seltherin’s left eye twitched. The chalk almost snapped.

“Your aura,” he said suddenly, voice low. He leaned in without stepping through the threshold, eyes slightly unfocused, seeing something beyond the visible spectrum. “It resonates… strangely.”

Eric deadpanned. “Pretty sure that’s not a compliment.”

Seltherin ignored him. “Identify your elemental affinity.”

“My what?”

“Your resonance alignment,” he snapped. “Air, water, fire, earth—or none. Answer.”

Eric scratched his indecently smooth head. “Lightning? Apparently?”

Silence fell so hard it made sound. Somewhere, a quill leapt off a desk and clattered to the floor like a gunshot.

Seltherin went very still.

“Lightning,” he repeated, barely breathing. “A complex dual-element, is this common where you are from?”

Eric gave him a lazy thumbs-up. “Probably not? Pretty sure we don’t have affinities where I come from.”

“That’s absurd!,” Seltherin exclaimed “Every being has some form of affinity, quit toying with me boy.”

A slow wave of understanding crept through the benches. It wasn’t awe. It was the look people give a firework that hasn’t gone off yet—nobody wants to be near it, but everyone wants to watch.

Seltherin’s anger slid off his face. In its place settled something worse: competence.

He pivoted from the circle, spun toward the students, and clapped once. The sound cracked through the hall with magical authority. “Class dismissed. Now. File out. If any of you touch this array before it is inert, I will turn you into a salamander and assign you as my lab’s humidity sensor.”

Benches scraped. Robes rustled. The flow became a tripping river of students pretending they weren’t curious, then breaking and peaking back anyway. Eric caught a half-dozen quick looks from the front-row girls—the seesaw of scandal and curiosity—and wondered if embarrassment could become a magical element.

Seltherin waited until the last robe vanished through the rear archway. The hush that followed was somehow louder than the noise had been.

He turned back to the dome, rolled his shoulders back into something like calm, and reached into a closet. “You,” he said evenly, “are going to stand very still. I am going to lower the containment for precisely three heartbeats. You will be wearing this coat before I raise it again.”

He snapped his wrist. A long, rune-stitched coat appeared in his hand—thick, charcoal gray, lined with faint sigil work at the cuffs. With another gesture, the barrier whispered open just enough to admit the garment. The coat passed through like a fish disturbing the surface of a pond; the barrier re-sealed with a crystalline chime.

Eric grabbed the coat like it was a rope tossed to a drowning man and shrugged into it with the panicked grace of someone who had forgotten how sleeves worked. It hung to mid-calf and smelled faintly of ozone and lavender. Dignity returned at least to the point where he looked like a particularly hairless runaway priest.

“Oh thank God,” he said, cinching the front closed and discovering—saints be praised—buttons. “Team Pants back on the board, well close enough.”

Seltherin’s mouth twitched. It might’ve been a smile if he weren’t twelve crises deep. “Listen very carefully,” he said, all professor again. “The array pulled your vessel entirely into our plane. Your octave is still unsettled. If we do not get you scanned by the Arcane Anomaly Authority immediately, your resonance may stabilize in our register, and your home plane will become unreadable.”

Eric stared, coat half-buttoned. “You just made up half those words.”

“Every one of those words has a textbook,” Seltherin said crisply. “And several footnotes. The important bit is this: if we hurry, we may be able to send you back.

The words hit Eric like soft armor. Hope inflated and then tried to disguise itself as a shrug. “Right. Authority. Scans. Fix my cosmic settings. Got it.”
