Marking the Route

Colm returned from his survey a few days later with the mountain's exact height finally confirmed, three thousand nine hundred and thirty meters precisely, close enough to Thoth's earlier rough estimate to confirm the calculation had been sound, precise enough now to actually build from. He set to work translating the entire three-realm route into something properly mapped, rather than just a rough sketch spanning an abstract sense of "very high" and "very deep."

"...Three thousand nine hundred and thirty meters," he said, working through the numbers with careful, methodical precision. "That's our actual vertical scale for the entire mountain, base to peak. Everything else, the drop, the corkscrew, the loop, all of it measures relative to that."

He and Arista walked the mountainside together over the following days, marking each proposed pillar location directly into the terrain, small, driven stakes at first, temporary markers indicating exactly where the permanent adamantium supports would eventually rise.

"...First support goes here," Arista said, driving a marker stake into the mountainside at the exact point where the initial drop finally met solid rock. "This is where the corkscrew anchors the track properly, the drop above this point stays completely unsupported, open air the whole way down. This is the first place the track needs anything to physically hold onto."

Colm cross-referenced the position against his survey notes, confirming the exact elevation. "That puts this marker at roughly thirty-eight hundred meters. Just shy of the summit itself."

"From there," Arista continued, "the corkscrew does its job, gets the track properly anchored against the rock, and hands off into a straight run down the mountainside, following the natural slope the rest of the way toward the loop."

They continued down the mountainside together, marking each subsequent support point along that straight descending section, closer to the mountain's base where the terrain finally leveled toward the tunnel entrance.

"...Loop sits around eighty meters," Colm reported, marking the elevation carefully onto his growing chart, "right before the terrain flattens into the tunnel approach."

Bram, hauling the heavier marker stakes for the lower elevations, glanced up at the sheer scale of it all. "...We're marking four kilometers of mountainside. That's an enormous survey."

"It's a big project," Arista agreed, unbothered by the scale at this point. "But marking it properly now means the construction crews know exactly where every single pillar goes before a single piece of steel or adamantium gets moved into place. No guessing, no adjusting mid-build."

Petrov, reviewing the growing chart alongside Colm, nodded slowly. "This also gives us a proper materials estimate. Knowing the exact elevation of every support point lets us calculate precisely how much adamantium reinforcement each one actually needs, rather than over-ordering out of caution."

"Efficient and accurate," Marek said, checking the marked elevations against his own structural calculations. "The load each pillar carries scales directly with its position along the drop, the ones higher up need less reinforcement, since the cart hasn't built full speed yet. The ones lower down, right before the loop, need the most."

Arista studied the growing chart, dozens of small stakes already marking their way down the mountainside, each one destined to become a permanent, load-bearing pillar rising from the exact elevation Colm's careful survey had confirmed.

"...Four kilometers," she said, staring up toward the distant, cloud-obscured summit, then down toward the mountain's base far below, where the loop and tunnel would eventually need to sit, feeling the sheer, genuine scale of what she was about to build settle in properly for the first time. "That's considerably taller than anything I've ever built vertically before."

"Taller than the gun," Bram said.

"Taller than the gun," Arista confirmed, grinning despite the scale of it. "Good thing this one's not a weapon."

"No," Colm agreed, marking the final stake at the mountain's base. "This one's just supposed to be fun."

Construction began soon after, pillar by pillar rising exactly where each marker stake had promised, and Thoth arrived partway through, drawn by the same restless curiosity that had once led him to help calculate the mountain's own ski lift, wings folding as he settled near the base of the first completed pillar, dish tilting to study the growing structure.

"...Query," he said, studying the single completed pillar and the empty stakes marking where dozens more would eventually rise. "What is the operational function of this structure?"

"It connects three realms," Arista said, glancing up from her work. "Celestial, Dwarven, Demon. Same basic idea as the metro, just considerably more vertical."

Thoth processed this, dish rotating slowly. "A transportation network, then. Analogous to prior infrastructure."

"...Sort of. It does connect them, but that's not really the main point." Arista set down her tools, considering how best to explain it. "It's not built for efficient travel. Nobody's going to use this to actually get somewhere useful. The drops, the loops, the corkscrews, none of that's the fastest way to move between realms. It's actually a considerably slower, more indirect route than simply walking through the existing passages."

Thoth's dish paused, processing. "...Then what is its function?"

"Fun," Arista said, simply. "That's genuinely it. The whole point is the experience of riding it, the drop, the momentum, the loops. Nobody's meant to arrive anywhere more efficiently than before. They're meant to enjoy the journey itself."

Thoth was quiet for a long moment, dish rotating slowly, processing.

"...I recall this classification," he said finally. "I once asked Creator to ride on my back through open air, testing my own hypothesis regarding a concept I did not yet understand. The activity we later confirmed as 'fun.'"

"Exactly that. Same underlying concept, just built out of steel and adamantium instead of wings this time."

"This structure required considerable resource investment," Thoth observed. "Adamantium reinforcement, dedicated production lines, months of coordinated labor across multiple factions." He paused. "For an outcome that produces no measurable practical benefit beyond subjective enjoyment."

"...Yeah," Arista admitted, grinning slightly, waiting to see where this would land.

Thoth considered this for a genuinely long while, longer than his usual processing pauses, the dish rotating through several slow, deliberate cycles.

"...I find," he said finally, "that I do not classify this as inefficient."

Arista blinked, surprised. "...You don't?"

"No." Thoth's dish settled, steady now. "I once believed efficiency and worth were equivalent measures. I have since observed considerable evidence contradicting this assumption. The swing ride produced no material benefit, yet its construction generated measurable increases in observed happiness among children who previously lacked recreational infrastructure. My own experience of flight produced no practical outcome whatsoever, and yet I found myself, unmistakably, wanting to repeat it."

He turned his dish toward the rising structure, studying it with what might have been, in a being capable of such things, genuine appreciation.

"...This structure serves the same function," he continued. "It connects three realms not through necessity, but through shared experience. Beings who might never otherwise occupy the same space: Celestial, Demon, mortal, will sit together, briefly, sharing an experience with no purpose beyond itself." A pause. "I believe this constitutes a form of value my original operational framework failed to properly account for."

Arista sat with that, genuinely moved by the sheer, careful thoughtfulness of it. "...Thoth, that might be the nicest thing you've ever said."

"It was not intended as a compliment," Thoth said, echoing his own familiar phrasing from months earlier. "It was intended as an accurate reassessment of my prior operational assumptions." A brief pause. "Though I acknowledge it may function as both simultaneously."

Arista laughed, delighted, watching him study the corkscrew's rising frame with quiet, genuine interest.

"...Would you want to ride it?" she asked. "Once it's finished?"

Thoth considered the question with the same careful deliberation he gave everything.

"...Yes," he said finally, simply. "I believe I would."

"I'll save you a cart," Arista said, grinning, already picturing the sight of a mechanical dragon strapped into a roller coaster cart alongside the rulers of Heaven and Hell. "Though I make no promises about how comfortable the seating is."

"Comfort," Thoth said, "is secondary to the experience itself." He paused. "I have learned this, also, from you."
