A Proper Crane

Once the blueprints had been finalized, the demon builders had started working under Petrov's supervision, and construction had unfolded steadily over the past few days while Arista's attention had remained occupied elsewhere, first with the cloud material testing, then with Squishy's own unexpected pillow project.

Petrov moved through the growing site, checking measurements against the finished blueprint, confirming each sleeping quarter's proportions matched the corrected design before the crew moved on to the next.

"...Foundation width's within tolerance," he confirmed, checking the third sleeping quarter against his own marked rod. "Entrance width matches the revised spec exactly."

The lead builder glanced over, mild curiosity crossing her expression. "You've done this kind of work before. Coordination, I mean, not the actual masonry."

"Project engineering," Petrov said. "Gantt charts, resource allocation, catching problems before they become expensive. I did the same thing for the metro, back when Arista was still convinced she could track every moving piece in her own head."

"...You're better at this than you let on," she said, approving, watching him catch a minor discrepancy in the fourth structure's wall thickness before it became an actual problem.

"I've had practice," Petrov said, simply, already moving to the next checkpoint. "Mostly practice telling one very bright demon exactly where she'd gone wrong."

By the time Arista's attention returned to the project a few days later, the shoreline had changed considerably. The community house was taking shape alongside the first two sleeping quarters, while foundations and partially raised walls marked where the remaining structures would follow.

Over the following week, the work continued steadily under Petrov's supervision, one structure after another taking final shape along the shoreline.

The lead builder found Arista at her workshop once the last of them was finished.

"...Come see it," she said, simple and direct. "It's easier shown than described."

Arista followed her down to the shoreline workshop, where the finished structures sat drawn up on the sand, ready for the next step, the community house and its cluster of sleeping quarters all standing at true scale for the first time.

She stopped for a moment, taking in how much had appeared along the shoreline.

"...How did you do all of this so fast?"

The lead builder looked faintly amused. "Once we saw the scale of the project, I brought in thirty extra hands from the Demon Realm."

Arista blinked. "...Thirty?"

"You wanted five sleeping quarters and a community house."

"...Fair."

The community house sat wide and welcoming, the same circular gathering alcove from the original mansion recreated at a scale suited to smaller, staggered groups, grooves carved carefully along every wall for proper water circulation. The sleeping quarters clustered around it, each showing a clever, considered solution to housing groups efficiently, alcove beds set at varying heights along the interior walls, nestled and private, sized for ten mermaids per structure without ever feeling cramped or impersonal.

"...This is beautiful," Arista said, tracing the nearest alcove with genuine appreciation. "The staggered heights, that's not just efficient use of space, is it?"

"No," the lead builder confirmed. "Selen mentioned, during one of her explanations, that resting at slightly different depths within a shared space felt more natural to her people than everyone sleeping at a single, uniform level. We adjusted accordingly."

"...Fifty mermaids, total, per rest stop," Arista said, doing the math against Selen's earlier estimate. "That matches a full traveling school comfortably, with a little room to spare."

"Exactly the target," the builder confirmed. "This is enough for the first rest point, fully outfitted. Whenever you're ready to transport it."

Arista studied the finished cluster, the logistics of the delivery settling in now that the structures actually existed and needed moving.

"...We'll need the temporary buoyancy platforms fitted underneath each one before any of this goes anywhere," she said, already walking the length of the community house, checking where the sealed chambers would attach. "Same design as the ones we used for the tube itself. Nothing floats on its own until we put it there."

"That part's yours, I take it," the lead builder said. "None of us know the first thing about sealed air chambers. We stuck to what we're actually good at."

"Fair," Arista said, already sketching the attachment points in her head. "Give me the rest of the day."

Work continued through the afternoon, and by evening six flat platforms stood ready, each sized to its structure's individual footprint, sealed air chambers built into their undersides exactly as they had been for the tube itself, their watertight seams checked twice before Arista trusted any of them near actual water.

Getting the houses actually onto the platforms turned out to be an entirely different problem.

"...Thoth," Arista called out, watching him settle nearby to observe the delivery preparations. "Could you lift this?"

Thoth studied the community house for a long moment, dish tilting through several small adjustments as he calculated.

"...Negative," he said finally. "This falls outside my strength parameters."

Arista stared at him, caught off guard. "...Wait, seriously?"

"The tube was a compact, continuous structure with a predictable load distribution," Thoth said. "This structure carries greater total weight despite its similar footprint, and that weight is distributed unevenly. Even accounting for the reinforced grip points built into the frame, the total load exceeds what I can safely lift unassisted."

"...Right," Arista said, feeling faintly foolish. "I was picturing the pipe again. A house just weighs more."

"...You can still help," Arista continued, already sketching the revised approach. "Just not carry the whole weight alone. We build a pulley system, four sets, fixed and movable blocks together, one at each corner." She glanced toward the lead builder. "I'll need your crew on the ropes alongside mine. You take the top, Thoth, keep it level and stop it swinging while we move it out over the water."

Thoth considered this. "A distributed effort, rather than a single load-bearing point. That falls within acceptable parameters."

Building the lifting gantry took the better part of two days. A tall, heavily braced timber framework stretched from the dry sand out over the shallows, its overhead rails standing comfortably higher than the houses themselves. Four traveling tackle assemblies hung from those rails, one for each reinforced grip point, sturdy rope threaded through fixed and movable pulleys to multiply the pulling force available. Once a structure was clear of the ground, the traveling blocks could be hauled seaward together, carrying the suspended load sideways over the water while Thoth controlled its sway and kept it level.

Once the rigging finally stood ready, builders and crew alike took up positions at each rope, nine people to a lifting line, the pulley system multiplying their combined effort while Thoth settled directly above, claws hooked carefully into the reinforced grip points alongside the tackle lines.

The first buoyancy platform floated in the shallow water beneath the far end of the gantry, held steady by guide ropes while Claire watched its position from nearby.

"...On my mark," Arista called, checking each rope crew in turn. "Slow and even. Nobody outpaces anybody else."

The house rose slowly, evenly, four ropes and four claws working in careful coordination, Thoth's strength handling the fine centering work as the structure cleared the sand.

"...Hold there," Arista called once the base was safely clear. She looked along the gantry toward the waiting platform. "Travel lines. Same pace. Slow."

The four overhead blocks began creeping seaward together, the suspended house moving with them a little at a time. Thoth stayed above it throughout, correcting each small swing before it could build into anything worse, until the structure finally hung over the center of the floating platform.

"...A little more to the left," Claire called, watching the alignment from the shallows. "Steady... steady..."

The house descended the final distance and settled onto the floating platform with a soft, solid thud, exactly centered. The platform dipped noticeably under the added weight before rising back to its intended waterline.

"...Structural integrity confirmed," Thoth reported, releasing his grip and settling back to observe.

"Buoyancy holding," Claire confirmed, checking the platform's waterline. "Perfectly balanced."

Arista let out a breath she hadn't quite realized she'd been holding. "...Five more to go."

By the end of the following day, all six structures floated securely on their platforms, the entire cluster now ready for transport.

Arista turned toward Claire and Nettle. "...Now I need to work out the tow arrangement..."

Nettle considered the load, doing quick mental math against her own ship's known towing capacity. "Even floating, that's still a lot of drag moving through open water. It's not like towing something entirely weightless just because it's buoyant."

Claire nodded, confirming the concern. "The community house alone would demand a lot of pulling force, given its size."

Arista looked toward Nettle. "...How far along is the second boat?"

"Nearly done," Nettle said. "They're putting the finishing touches on her now. She'll be ready tomorrow."

Arista nodded, looking back toward the floating structures. "...Then we split the load across both ships."

Nettle grinned, already seeing where this was going. "My original boat handles the community house and one sleeping quarter, the heavier half of the load. The new ship handles the rest."

"Distributing the strain evenly across both engines, instead of overloading one," Claire said, approving. "More sustainable, and it means if one tow line or one boat has any trouble, we're not risking the entire delivery at once."

"Exactly that," Arista said, already sketching the revised transport plan. "Two ships, two separate tow lines, splitting the load by actual towing difficulty rather than just structure count. The community house alone probably creates as much drag as two or three of the sleeping quarters combined."

Nettle studied the plan, satisfied. "I'll coordinate with my guild. We can run both ships in parallel, keeping pace with each other rather than racing ahead independently."

"Good," Arista said, relieved to have the logistics solved. "Then we move the first rest stop tomorrow. Fifty mermaids' worth of comfortable homes, ready and waiting the moment we get them into position."

The lead demon builder studied the finished structures one final time, something quietly proud in her expression. "...I am glad to be part of this. It has been some time since any of us built something meant purely to comfort someone else, rather than simply to house them."

"That's exactly what I wanted," Arista said, grateful. "Thank you. All of you. It's what these people deserve."
