Chapter 675: Command

The Command Class examination began with the same three phases as everything before it, but Grey could tell almost immediately that the test had stopped caring about memorization alone.

The first material appeared in front of him as a dense black alloy threaded through with silver, and beneath it came the familiar spread of questions asking for its properties, processing limits, compatible materials and the sort of functions it was best suited for.

Grey answered without slowing down.

The next several were the same, only more specialized, materials he had already memorized while building up his knowledge toward Dominus Class appearing one after another. Some needed specific temperatures, others became brittle around particular energies, and more than a few behaved completely differently once paired with certain Nullites or Resins, but Grey had already shoved all of that into his head months ago.

Then the first strange one appeared.

It looked like a pale blue crystal at first, something Grey recognized as a Command Class conductive mineral commonly used inside energy transfer circuits, but there was a second line beneath the material name that made him stop.

[Command Imprint Detected]

Grey’s eyes narrowed.

He reached toward the hologram and rotated the material, watching thin golden patterns shift through its interior whenever his hand moved. The crystal still had all of the properties Grey remembered, except its conductivity rose sharply whenever energy flowed in one direction and collapsed almost completely when it was forced back the other way.

’What the hell?’

The information Grey had memorized said nothing about that.

He expanded the deeper analysis and finally found the difference, a Command left behind by some living being had attached itself to the raw material before it was harvested. That Command hadn’t simply added an effect on top of the crystal, it had changed what the material fundamentally did, taking something naturally balanced and forcing its character toward one purpose.

Grey’s interest immediately replaced his annoyance.

"So you can do that?"

Hollen didn’t answer from outside the chamber, though judging by the slight movement of his mechanical lenses, he’d heard him.

Grey worked through the question carefully, getting the natural properties right while missing part of how the embedded Command changed its behavior under prolonged load.

The system marked several sections partially correct before moving on, and that happened twice more near the end of the phase as materials appeared carrying Commands that had altered hardness, heat resistance or even the way their Faces naturally preferred to separate.

Grey wasn’t upset. If anything, this was the first useful thing the certification process had taught him.

He had memorized an absurd amount of information, but that wasn’t the same as being systematically trained through every part of the profession. There were entire assumptions buried inside proper Mech Tech education that Grey had simply skipped over while brute forcing his way forward, and apparently Command Class was where some of those holes finally started becoming large enough to notice.

To be able to use your Command not just to infuse the final material, but the raw materials themselves to tweak them for your needs... that was fascinating.

The last material disappeared.

[PHASE ONE COMPLETE]

[Accuracy: 97.3%]

—

Hollen inhaled sharply.

The two Vanguard candidates looked at one another, then back toward Grey, and neither seemed to understand why his expression had brightened after scoring worse than he had on every earlier test.

Grey barely cared.

The second phase opened before he could think about it much longer.

This time, the blueprint took long enough to form that Grey could actually watch its internal structure assemble, layer after layer locking together until hundreds of thousands of Faces hung in front of him.

The system asked the same questions as before, identify the function, identify the ideal Spirit, explain the expected Sync relationship, but Grey noticed a problem.

When he thought he found an answer and was about to put it in, he paused and realized there might actually be a second, and then a third.

Grey frowned.

The blueprint was built around a heavy defensive shell with a central propulsion structure, something that could theoretically function as armor, a charging platform or even a mobile siege piece depending on what Spirit sat at its center. This blueprint could actually become more than one thing.

At lower Classes, the Spirit needed to align with what the mech already was, but Command Class seemed to changed that relationship enough that the Spirit itself could help define what the final product became.

That made perfect sense. A Command Class Spirit would likely have a Command of its own, and thus it would be able to have a similar effect to the overall end result as the creator could have had on the original raw materials.

Grey rotated the structure slowly.

A defensive beast Spirit would turn the entire mech toward reinforcement, thickening its response patterns around impact and allowing the propulsion system to act mostly as stabilization.

A predatory charging Spirit could instead use the same architecture offensively, pushing the propulsion network to the front while treating the shell as something designed to survive its own collisions.

Then there was the elemental route.

Grey shifted the internal channels and imagined a Fire Spirit sitting in the center, its own Command influencing the mech as it formed. Suddenly the propulsion network became something closer to sustained thrust, the armor turning into heat shielding rather than simple defense, and the same blueprint that had looked like a moving fortress became something far more aggressive.

’So the Spirit isn’t just matching the mech anymore.’

At Command Class, it could help command it.

Grey selected three valid Spirit families instead of one and adjusted the answers around each, explaining how the final function would shift depending on which path the Mech Tech chose. Hollen watched the responses appear one after another while the two candidates behind him fell completely silent.

[PHASE TWO COMPLETE]

[94.7%]

—

The third phase was where Grey finally understood why Command Class Mech Techs needed to be more than good builders.

The first few mistakes were ordinary enough, a reversed channel here, an inefficient Face arrangement there, but halfway through the phase a blueprint appeared that looked wrong no matter how Grey rotated it. One section of reinforcement alloy simply refused to match the pressure profile around it, yet moving it anywhere else only created a different failure.

Grey stared at it, but then he remembered the first phase.

His hand shifted away from the blueprint and toward the material itself.

The alloy carried a Command.

It had been altered toward rigidity so aggressively that the blueprint was trying to force a material into a position it could no longer properly fill. Rearranging the Faces wouldn’t solve anything, but changing the Command from pure rigidity toward controlled compression would let the same material absorb the pressure instead of fighting against it.

Grey reached into the holographic settings and adjusted the embedded Command.

The entire blueprint changed.

Not dramatically, not in a way someone unfamiliar with the design would even notice, but the problem disappeared all at once. The alloy’s behavior shifted, the Faces settled into the positions they had already occupied, and what had looked like a structural mistake stopped being one without Grey moving a single piece.

His grin widened.

The later questions pushed the same idea harder, some carrying genuine blueprint flaws while others only looked wrong until the Command attached to a material was modified. Grey made mistakes here too, especially when the test expected him to recognize which Commands could safely be altered without destroying the original properties, but the more questions he answered, the faster he adapted.

By the final blueprint, he wasn’t looking only at Faces anymore.

He was looking at what every material had been told to become.

The chamber dimmed.

[COMMAND CLASS EXAMINATION COMPLETE]

[Calculating Results...]

—

Outside, Hollen had gone completely still, while the two Vanguard candidates stared at the final score waiting to appear. Grey folded his arms and looked toward the result with more curiosity than concern, already thinking about how much he could do with Command-altered raw materials once he had time to experiment properly.

Far away, the completed examination record reached the Board.

Axion-9 opened the first phase results.

[Accuracy: 93.9%]

A thin line of light narrowed across his mechanical face.

Then he sneered.

If this was the Command Class result, Grey didn’t stand a chance.
