Uppercrust toiled.
Sometimes, when he had still been searching for his cure, he'd wondered what it would feel like to reach the other side; how his relief would last, and whether he would remember his weakness enough to be thankful for his strength.
The likes of Bonesaw and Sphere had fallen through, but the wet Tinkers of America were more than two monsters or three household names. The world was more than America, and once the walls between countries had been as thin as glass to his means, no more than a single step away for a man not yet totally withered on the vine.
Cask of Anchorage, the alchemist, physician treating thyself. Blasto in Boston, who wrung Bonsai from the tree of life. Pharmakon of Portland, a doctor who could kill disease but never treat the patient. Semicolon of the Bible Belt, who cast her birth flesh aside before anyone could stop her. Cranial of Toybox, who could preserve mind and memory but not power or will. L'oeil of Bordeaux, that bionics engineer crawling towards the elegance of life. Autocthon the itinerant mercenary, who carved a bloody line down South Africa. Lab Rat the vivisector, long consigned to the casket of the Birdcage. Jingoro the sculptor, who fled from Kyushu into the thicket of India's cold capes. Knave of Spades, transforming himself as Trump among the Suits.
It had taken Uppercrust only weeks to admit that this was a dead end, a place as far removed from his own specialty as he was from the world - the child behind the pane of glass, the man behind the cell of force, you can look, but you can never touch. It had taken him years longer to really give up, still passing all wet Tinker news across his desk like an apotropaic, just to check and be sure that none of it would ever resonate with his power or be worth gambling on. To know with certainty that he had tested every opportunity at hand, and when he lost, it would be without error or regret.
The final calculus of survival never really left his mind, not before this final effortless cure. How much will I have to give up, if I want to live? If I want to so much as linger in the world?
And that door had always been open to him, if he was willing to give up even more than he'd offered Apeiron. Forsaking control, or autonomy, or power, or life, to preserve the faintest shadow of what he was already going to lose. He'd almost gone through with it, taking Cranial and Cosmist on retainer to see if an acceptable compromise could be reached between his agency and his quality of life; but Cosmist had just laughed when he heard what Uppercrust was running from.
It never gets any better, you know, the Russian Tinker had said, gesticulating through a thick mouthful of analog tape. Do you think you're suffocating now, because you're dying and weak? Becauses I can keep you alive, but I can't give you liberation. You will always despise your limits: our bodies will always be cages, no matter how vast our confines.
Uppercrust could have worked with him without regard for the disrespect and discomfort he felt in that moment, because he was a professional, and he knew the other man was a professional, too; he could have sympathized with Cosmist, because he understood that there were things Cosmist was running from in his own right, the broken glass and shatterpoints which defined every cape's flight from mundanity. But he'd understood at once the pointlessness of it all, the real meaning of the joke that there was no such thing as a 'healing' power, and left the collaboration at once for less bitter pastures.
It wasn't that there were no healing capes, or that all healing powers were secondary applications of a wider powerset, or even that there were no healing powers without side effects. It was that even the parahuman powers which could heal existed for a purpose that had nothing to do with setting things in order or mending the broken. Uppercrust never stopped looking for a treatment or a cure, but he'd never forgotten the black humor in the other man's voice, the knowing insinuation that even if he found health, it couldn't make him happy. It was easy to castigate a woman like Emily Piggot who chose to wallow in her illness; it was hard to disagree with a man who had crawled from the very same sort of pit he hoped to escape.
And now-
Now Uppercrust was pretty sure that Cosmist was just a little bitch.
His workshop sprawled out around him like a hardware depot, Thurin-Ist the beating heart of a growing industrial complex, and he moved from machine to machine with a drive that shocked him even now. He was nothing more or less than human - fallible and weak, an ape stretched out upon the rack, defaced by the indignities of flesh.
It felt like grace, unquestionable and undeserved. The right to move through the world like he was finally alive again, every breath as easy as the last.
In one corner of the workshop he watched a small army of well-paid contractors manufacture his new Tinker rifles, repurposing the hardlight projectors of his shields as photonic cannons. His previous tries at the concept had been sent soundly to the recycling bin: the most he'd ever managed was a kind of long-range hardlight jackhammer which painstakingly jerked a large bullet-sized shield back and forth, and he could never get kinetic uncoupling to work on any installation smaller than a minivan, so the jackhammers would recoil like minivans, too. It had never been worth it, not when he could just ring up one of his contacts and have a gattling gun or a crate of machine guns sent up from downstate.
For the new model he was working smarter, not harder. By studying the destabilization of his shields under controlled conditions, he'd finally completely modeled both their internal geometry and the pattern of their dispersal into unbound photons: his new rifles worked by projecting small, carefully-shaped 'shield bubbles' under immense internal stress, then applying a matrix of shear forces that caused them to explode. The shields were, in a sense, both the projectile and the propellant, a blast of hardlight grit which had taken significant coaxing to cohere as laser rounds and not as cones of shotgun spray. By occasionally rotating between two chambers, the rifles could vent coolant over one overtaxed projector in the time it took the other projector to overheat.
-if he was being completely honest with himself, this assembly line probably still wasn't worth it. There were few enemies he'd ever have to lower himself to fight at this juncture, and few enemies who couldn't be taken down with conventional munitions, not to mention that most Brutes and other high-survivability capes could usually be more effectively taken down with surgical precision or heavy bombardment than massed infantry fire.
But once he'd started testing his new limits, he hadn't been able to stop. Isolating the most exotic components and assembling them by hand for others to install, sinking into inspiration until the secrets of the universe were practically screaming to be heard, rushing to churn out the first thing he thought of and straddling the impossible knife's edge of mass-production. It would have predictable if that was the hidden cost to his devil's bargain, if he'd been high out of his mind in a Mad Science fugure, but the reality was much more embarassing: deep down, buried after years of building 'boring' energy shields, there was still a part of him that just thought ray guns were really cool.
His subordinates seemed to agree, at least, eagerly leaping into 'laboratory testing' with the verve of men and women betting on who would be the best crack shot. Even now they were probably neglecting several gun safety rules in the backyard in order to play laser tag with phasers on the lowest setting.
In another corner of the workshop, he was supervising the assembly of something much more irreplaceable than light rifles. If his old personal-scale shield systems outstripped the best body armor on the planet, the new models were fully turning a corner into the world of Tinker power armor.
As always, articulation was the bane of every mechanical assyst system, and so for the most part he'd neglected it: a series of emitters along a wireframe insert in his costume could produce an array of phased shields around each limb and joint, as if he were standing in a suit of invisible full-plate. By toggling the interference between each sheld emitter, he could allow them to selectively lock together instead of phasing through one another. That was the secret of his standing support system, a complicated trick he pushed to its limits just to let him stand upright for more than a few minutes at a time.
Now he didn't need the support, and he could push further than ever before. He'd gone back to the drawing board, taking inspiration from the Dallon girl, and now each personal shield emitter was paired with an undersuit that continuously measured the exact shape of the person who wore it. A fail-safe computer processor in each each emitter transformed that information into a control template for the projection of a single continuous force field held suspended a milimeter from the skin, carefully following the wearer's movements. As long as you didn't overstress the integrity of the shield, it was superstrength and heightened durability in a single package.
Then he went back to the drawing board again. His best design was still never going to be manufactured in numbers without a lot more help from the Matrix than he was currently comfortable asking for, but he'd managed it for himself. The shield system in his costume projected a complex and well-managed stack of countless increasingly-dense layers at a time, creating redundancy for if one of them was ever broken.
Then he carefully integrated the explosive destabilization principles from his rifle designs. If one of the shields was ever hit hard enough to break, its internal stress would be released along an equal and opposite vector, essentially transforming into a perfectly-angled explosive charge and counterbalancing any changes in momentum. A high-level Brute could punch him, and as long as it was within tolerance for his buffered shield system, he'd just stand in place.
Still, he thought. It might be a good idea to extend lab testing before I wear a suit made of high-energy explosives in the field.
By now he'd almost stopped supervising the production of his tech, trusting his assistants to manage what he'd shown them - he wasn't the type of person to look down on unskilled laborers, disrespect what non-Tinkers were capable of, or hire potential traitors. Only uncertainty stayed his hand, and in the light of Thurin-Ist, there was little uncertainty to be had about the limits of his devices. Only perfunctory checks to make sure everything was within stable boundaries, taking regular circuits around the room.
In the last corner of the workshop, he sagged back into his chair, less as an act of exhaustion than of gluttonous indolence. After the latest hasty round of expansions, it was where he ended up doing his personal Tinkering, now carefully hidden behind several one-way optical screens. The latest version of his costume was lying across a table to his right with the batteries carefully removed, waiting for him to run more checks on it; Thurin-Ist's filing cabinets and papers were off to his left, interleaved with sketches from his final, most cutting-edge project.
Pun not intended. A corkboard was taken up almost entirely by measurements of Apeiron's Final Slashes, all HD photographs and optical analyses, and Uppercrust had gone over them with a fine-toothed comb. The stable confinement of colossal power to an interactive two-dimensional plane.
It was yet another holy grail the boundless Tinker had casually left behind, and one with the potential to advance Uppercrust's science by leaps and bounds. It didn't matter if the secondary spatial shear could only be formed at high velocities, if it was a current of moving space-time, because he'd already more or less confirmed from study that the effect was stable under relative motion and angular rotation. A dual-vector current could be adjusted to the Earth's movement or contained in a cyclical pathway, creating a two-dimensional panel of high-energy warped space that was impenetrable to anything but the strongest Annihilator capes.
But he hadn't gone through with trying it.
It wasn't fear of the physical risks that stayed his hand. Already he was working with incredibly dangerous technology, unleashing the full mechanical force implied by systems that could hold back hurricanes and tidal waves. It wasn't resource limitations or anything of the sort, not now that he was working faster and with better support than he'd ever had in his life. It wasn't even fear of getting caught cribbing notes from his new benefactor; by all accounts, Apeiron didn't mind people following in his wake, as long as they weren't doing evil.
It was the fact that even if Uppercrust knew how to recreate a version of the effect for himself, he still had no idea how Apeiron had done it. And that was normal for dealing with other Tinkers, but seeing it from Apeiron still put him in a mood that was hard to describe.
Everyone who seriously thought about it for more than a few minutes at a time knew that Tinkers were breaking the rules. Maybe the physics was real, but the science and engineering was not: if you could turn a toaster into a nuclear reactor with the supplies you found in your garage when no-one else could, that wasn't science, it was just magic. Everyone knew it, but no-one said anything, because how could they prove it? In a world where a man could shoot fire from his hands, how could you prove that someone else's flamethrower was an anomaly just because it had unnatural fuel efficiency? Weren't the laws of physics tumbling down around all their ears?
And Uppercrust had known that it was proven from the moment he saw Thurin-Ist, even before it had the chance to dissect his schematics, because he understood what all of Apeiron's talk about 'quality boosters' really implied.
Tinkers often had the ability to create high-performance equipment from low-performance components and materials. That meant, by definition, that a Tinker's power could take invisible steps to maximize the performance and utility of everything it touched, arranging matter and energy with a mastery of composition and balancing of forces that put all human hands to shame.
But what if you were a Tinker who specialized in powers, and you could toy with parahuman powers as easily as if they were machines? What would happen if you took that 'performance maximization' and isolated it? What if you distilled all that physical optimization, and overclocked it, and funneled it into something a lot more rustic than a laser pointer or a computer chip?
Uppercrust wouldn't have said it out loud, but he had a feeling the result would look a lot like Thurin-Ist.
A mastery of composition and balancing of forces that puts all human hands to shame... except Apeiron.
Uppercrust's illness ended up taking a higher toll on his peripheral than his central nervous system, disrupting the very feedback loops that told his body how to keep itself alive, but there was a time when he'd had to prepare himself for the possibility of cognitive decline, and he still remembered what he'd learned. The mechanisms that kept a human brain in touch with reality were terrifyingly fragile, and the results spoke for themselves - even without Stranger powers, it was possible for a human being to be so cognitively impaired that they didn't even know they were cognitively impaired.
In this downtime, the closest he came to Cosmist's melancholia was this: he didn't know how he thought the universe worked anymore, and he didn't know how much of what his Tinker power told him about science was really true.
He turned the pages of Thurin-Ist for a long time, flipping between schematics as if to confirm he was still in good standing with the laws of physics, to see if it would vouch for his understanding, waiting for the vertigo of his shifting universe to subside. Finally, he stood again, slipping through the curtain surrounding his cubicle and setting for the nearest balcony. Night had fallen without him noticing until he checked a clock, and the moon was just rising.
He stared into the silvery-black disk, then, wishing any offering would be enough for the friend he'd finally buried. But all the old pain... it didn't ache any more, and his confusion just didn't seem to matter as he looked at the stars.
Whatever the truth of this universe is, however strange and confusing it may seem here on Earth... it can't hide from us forever. Because there are worlds these powers can't reach, or which they have yet to breach, and places we haven't bent.
And whatever our powers think they're hiding from us... they can't keep us from the truth forever. Because there's a way behind the curtain, and doors to the backstage, and someone who will fling a light into that darkness for the rest of us to see by.
And even if we're just misled fools who don't know what we're really doing... if we've ever made a difference with these powers, then I think that's enough.
The door opened behind him. Someone began to speak.
"Sir-" Ferrona said. Saw what he was doing, then seemed to think better of it. "Ah, I'll give you that status update later."
"No, it's alright." Uppercrust smiled. "I've already said my goodbyes."
