It was still dark out, before dawn.
The west fields were bare, harvested and tilled under, smooth dirt underfoot. Plenty of space. No snags or sharp edges.
Gotri couldn't stop grinning. Adela was almost sick with nerves. The We hovered anxiously, and ran back and forth in the dimness, half-seen arachnids on a dim slumped mass, spreading it out, and out, and out again.
And many more besides, both crew and observers. It was Clan Huzkul and their guests, Viceroy Franceso and his council, who had perhaps the best view, sitting atop the walls of the citadel as the sky grew lighter. From behind and above them hoses descended, thick as a thigh and anchored to the very tops of the twin towers. Below and in front of them was a ballet of movement, hundreds of men and spiders spreading layers of silk and rope netting across literal acres of ground. In the center was (or rather, had been, for now it was swathed under a tent of silk) a sort of boat like thing, a trimaran really, one long hull resting in a cradle with its two outriggers.
Twin engines sat on the outriggers, shiny and new, broad propellers on shafts pointing backwards, and only hours from being tacky with the final coat of varnish. (They had a schedule to keep.) Pipes stretched from the engines across to the center hull, a single boiler there shared by both. Gotri was quite proud of it- wood and metal were used with utmost restraint, power and resilience yes but always, always with an eye towards weight.
In truth he felt a little guilty, a little bad for King Belegar. He had lured a few of Barak Var's less restrained shipwrights into the project early as consultants, and one thing led to another and now there was a brand new 'engineering' clan, even if it was a small one, moving into the Karak. He thought it was a good thing, but, as always, there was a way things were done and it was not, in fact, how this has been done.
They had been drawn by the challenge. Make a ship, but make it light. Iron decks and bulkheads were traded for a steel skeleton and wood planking, and tests were run. Arguments were had. There was grumbling, but every dwarf knew that this was just an application of Morgrim's craft and it had been done before. But such a craft! It had not been called on in thousands of years; a craft of subtraction, to take away material en mass without taking away strength.
It was the halflings, though, who had sent them in a new direction, challenged them to raise their ambitions. Wood planking and steel beams? Hah! Woven wicker panels covered in silk, paper thin wood sheets laminated together over moulds, tensioned cords holding internal struts. Basket-making techniques. But strong, and light. More collaborators were called in from Karag Norn, experts in wood and ropes.
They were making a thing the ancestors had made before, therefore it was Traditional. They had no guidance on how the ancestors did it, therefore they had to try many different ways of doing it and see what worked.
Gotri loved it. And so did enough others that they stayed, ignoring the pleas of their kings.
Mentally, he shrugged. That was a Belegar problem, not a him problem.
In the current design, the only steel was in the engines, fittings, and weapons. The final prototype weighted a twentieth that of the initial design, while having nine-tenths the strength. A featherweight ship that would barely float in water, sitting in the middle of a barren field, underneath a huge silk blanket that had finally been fully spread out by the spiders. Dwarves hustled forward, attaching the hoses and connecting the cloth to the citadel towers.
Thorgrim had promised six hours of liftgas on this date, dawn to noon. The first sign of it was a sound like a vast rushing exhale and a sudden rippling surge as the silk slowly began to inflate.
Slowly, slowly the silk been to balloon up.
Francesco sat forward, blanket around his shoulders and a stirland style ale in his hands against the morning chill. He had finally, FINALLY gotten a process down to turn that damn spider silk into cloth. But as soon as he had, King Belegar had called him into a meeting with a manic glint in his eye (and Gotri grinning like a loon over his shoulder) and told him his immediate production was spoken for, here's cash on the barrel head. He didn't think more than a few sets of bedsheets made it out of the greedy hands of the engineers. Now, he finally got to see what all that hard work had gone towards.
At a distance far enough to properly take it in, it happened slowly. Inflating, taking on the shape of a squat cigar, the silk rose and began to tug against the netting of ropes that held it down. Crews scurried to untether the ropes from the ground and attach them to the hull, previously been hidden underneath the deflated envelope. They worked a few ropes at a time, a dance of shifting weight and ballast and attempts to enforce even inflation, until at last it was full enough to hold it's shape. By the time the last line was fastened to the hull the sun had risen clear of the the mountain ring and the final shape of the craft was clear.
Gotri knew it was nowhere near as complex as the stylized depictions and the few scraps of ancient airships they had to work from. A single bag full of gas instead of many cells in a rigid frame, a simple underslung hull instead of an integrated gondola. Four bolt throwers on pintels instead of cannon.
But that was ok. This was a proof of concept. It was the engines that mattered this time around. If the gas gave enough lift, if the envelope was impermeable, if the *wildly* experimental hull held together against the forces of wind and gravity... Then the engines would give it thrust, and direction, and control.
If it worked, they could elaborate more in the future. Proper testing first. They had gyrocopters for scouting and gyrobombers for heavy ordinance; airships weren't needed for either role.
Distance, persistence, and endurance. That had been Gotri's pitch. Distance, in that a single ship carrying fuel instead of cargo could probably make it to Cathay or Swamp Town without stopping, further if they knew the winds. Perstance, in that it could hover over a town or fortress for weeks without any need to land, keeping huge areas under it's guns limited only by how much ammunition could be carried. Endurance, in that there was enough space for a crew to move about and live aboard for the weeks or months the first two would demand.
Dreng had backed him immediately. The new loremaster peppered him with questions for an hour about whether it would support a team of air-dropped iron breakers before giving his unreserved support. Belegar's only reservation was in how to petition Everpeak for the gas, and it wasn't much of one. So by the time poor Franceso had arrived, he was rather steamrolled into providing the silk.
The envelope filled slowly for hours, the limited capacity of the hoses carrying liftgas making clear exactly how much volume was being displaced as time wore on. By midmorning, there was no more slack in the lines holding it to the hull. By late morning the hull was beginning to sway and hop in its cradle, and Gotri ordered the boiler lit.
It was half an hour before noon when the craft finally lifted free. Adela was standing there to smash a bottle across the bow as it did, having been prevailed upon to christen it as it took flight for the first time.
Cloudperch.
There was a longer khalazid name that meant something like 'watchtower/firing position upon the fake mountains above the real mountains' or something like that, but everyone knew it was backfilled. Cloudperch was catchy.
(Gotri had to thank Weber later- giving him a way to not only keep Adela from bugging him about being onboard for the first flight, but to have her thank him for it? Gold.)
At the top of the citadel towers, crews began reeling in the hoses, still attached to the airship. It drifted, pulled by those tethers until finally, with Gotri standing at the helm, the first airship in thousands of years docked. Not at Gretel's tower. The other one.
From where he sat with Mathilde drinking on her balcony, King Belegar sighed deeply. She raised an eyebrow at him but how to explain the complex mix of nostalgia, wonder, satisfaction, newly sparked ambition, disapproval of novelty, guilt over hypocrisy, pride, and tempered expectations he had swirling in his heart? After a moment she gave him a nod and they both returned their gaze below.
At noon precisely the gas shut off. Moments later the hoses were disconnected and tethers cast off, the Cloudperch given a gentle push away towards the open sky.
"Engage propellers! Throttle ahead one fourth! Prepare for initial rudder and turning tests!"
