Vokey slumped against the wall, inhaling the lingering aroma of failure and damp limestone. His grand escape, a supposed masterpiece of acid-base chemistry, had culminated in a peephole. A single, pathetic peephole that the guard now used to leer at him every so often, one monumentally unimpressed eyebrow arched in silent judgment. The humiliation was a physical taste, sharper than the acidic brine he'd so carefully prepared.
"My genius," Vokey muttered to the oppressive darkness, "is apparently only brick-deep."
Dissolving the mortar was a crude, brutish approach. It was the work of a demolitionist, not an artist. He needed something more fundamental, more insidious. To attack the stone itself, not the glue holding it together. He had to go deeper.
"Sufficient time has been allocated for pouting," a flat, disembodied voice echoed in his mind. "It is time for your next lesson: 'The Nature of the Atom.'"
"Oh, wonderful," Vokey grumbled, squeezing his eyes shut. "More inscrutable nonsense from the oatmeal dimension. Let me guess, an 'atom' is a type of particularly small, particularly boring rock?"
He didn't need to open his eyes to see the mental textbook appear, its pages displaying a diagram that looked like a celestial map for ants. A dense cluster in the middle, with tiny, angry specks buzzing around it like flies on a corpse.
"The elegant dance of the Five Elements—Metal yielding to Water, Water nourishing Wood—is a cycle of cosmic purpose," Vokey declared to his unseen tutor. "What you're showing me is a committee meeting. A profoundly dull one."
"An atom consists of three primary subatomic particles," Vex continued, utterly unperturbed.
Protons: Positively charged. Located in the nucleus.
Neutrons: Neutral charge. Also in the nucleus.
Electrons: Negatively charged. Orbit the nucleus.
Vokey scoffed. "So the universe isn't a grand, transformative cycle; it's just three pebbles locked in a loveless marriage? And this 'Dalton' fool claimed they were indivisible? He couldn't even get the first rule right. What a hack."
"When an atom gains or loses electrons, it becomes an ion."
Cation: An atom that has lost electrons, resulting in a positive charge.
Anion: An atom that has gained electrons, resulting in a negative charge.
"Let me rephrase," Vokey sneered. "A Cation is a victim of cosmic pickpocketing, and an Anion is a greedy little hoarder. It's the same sordid drama as Water's great divorce, just played out by things too small to matter." This, at least, was a concept he could work with. Theft and greed were the cornerstones of civilization.
But it was the next slide that gave him the key. The beautiful, terrible, sublimely petty key.
"Isotopes are atoms of the same element that have the same number of protons but a different number of neutrons. This gives them a different atomic mass."
Vokey's eyes snapped open. He sat bolt upright, the stale air in the cell suddenly crackling with malicious potential. "Different... mass?" he whispered.
He scrambled back to his mental textbook, his mind racing. The wall wasn't made of 'Stone,' a noble element of stability and strength. It was made of compounds, which were made of elements. Silicon, Oxygen, Calcium. But it wasn't just 'Silicon.' It was a messy, disorganized crowd of Silicon-28, Silicon-29, and Silicon-30, all jumbled together. They were chemically identical, but they had different weights.
"They're not identical twins," he breathed, a vicious grin spreading across his face. "One of them is a glutton, the others are starvelings. A family squabble I can exploit."
And if they had different masses, they could be targeted. Separately.
The plan bloomed in his mind, both elegant and exquisitely spiteful. He wouldn't dissolve the mortar. He wouldn't brute-force the wall. He would surgically dismantle it from the inside out using the system's own tedious logic. He would attune his power to the specific vibrational frequency of a single, common isotope in the stone. He would make it resonate, vibrate, and shake itself free from its heavier and lighter brethren. The bonds would shatter. The stone would crumble into dust.
"It's perfect," he gloated. "Sheer, pedantic, weaponized boredom."
To do this, he needed data. He had to know the average atomic weight to guess the most abundant isotope. He focused his mind, calling up the grand, blocky grid of elements Vex had shown him before. He found Silicon (Si). The number beneath it read 28.085.
"Note: Atomic Weight is the weighted average of the atomic masses of all naturally occurring isotopes of an element."
"Yes, yes, a weighted average," Vokey said impatiently. "Based on the naturally occurring isotopes found... where, exactly?"
"The standard atomic weights provided are based on the isotopic abundances found in the crust, oceans, and atmosphere of a reference planet designated as... 'Earth.'"
Silence.
Vokey's triumphant grin froze, twitched, and then collapsed into a mask of pure, unadulterated rage.
"EARTH?!" he roared, the word echoing off the stone walls, dripping with a fury that was almost elemental. "YOU'RE TELLING ME THIS ENTIRE COSMIC SYSTEM, THIS 'CENTRAL SCIENCE,' IS CALIBRATED TO SOME BACKWATER MUDBALL IN A COMPLETELY DIFFERENT PLANE OF EXISTENCE?! A-a provincial science?!"
It was the ultimate insult. The grand con wasn't just that the system was boring; it was that its core data wasn't even from here. The numbers he was about to base his hyper-precise, surgical escape on were from some distant, irrelevant dump where the locals probably still thought ferret droppings were a valid unit of measurement.
For a full minute, he paced the cell, a torrent of silent, creative curses flowing through his mind. Finally, he stopped, breathing heavily. He had no choice. He had to assume the isotopic ratios here weren't wildly different. It was a stupid assumption based on fraudulent data, but it was all he had.
He chose his target: Silicon-28, the most common isotope on... Earth. He would have to calculate the number of neutrons to fine-tune his 'frequency.' Mass Number (28) - Atomic Number (14) = 14 Neutrons.
"Fourteen little neutral pebbles," he muttered, closing his eyes and pressing his palm flat against the cold stone. This was demeaning. He was used to commanding the essence of Fire or the resolve of Metal. Now he had to concentrate on the resonant frequency of a specific silicon atom with fourteen specific friends. He focused his will, channeling his power not into a reaction, but into a vibration. A hum, a whine, a specific pitch of pure annoyance.
A low thrumming sound filled the cell. The stone beneath his hand grew warm, then hot. He felt a deep, grinding tremor run through the massive block. It was working!
With a final surge of effort, he pushed against the stone. It scraped backward with a groan of tortured rock. Freedom was inches away!
He pushed again. The block moved another half-inch... and then stopped. Utterly.
He threw his shoulder against it. It was like trying to move a mountain. Confused, he peered into the crack he'd made. The outer layer of the stone, a rough, six-inch slab, had indeed separated. But behind it was a sheer, impossibly smooth surface of polished black obsidian, crisscrossed with faint, glowing runes of containment.
His brilliant, isotope-shattering attack had worked perfectly... on the mundane, decorative stone facade. The actual prison wall was something else entirely.
From the hallway, the guard's voice drifted through the peephole Vokey had so generously provided.
"Having fun with the wallpaper, outcast? Let me know when you get to the load-bearing magic. I'll bring snacks."
Vokey let his head fall against the wall with a dull thud. He hadn't just failed. He'd successfully peeled a sticker off a vault door.
"Just... fucking... great."
