After thirty minutes, six of the flyers peeled off and left, leaving the remaining two patrolling the Highmarsh. “Let’s go, boys,” Cat said as the flyers loitered at the far end of the valley.
Morton was slightly surprised she was still with them, not to mention sticking to the deployment plan. He’d half expected her to take off on her own as soon as they were down. Under his guidance, the bubble’s plyplastic skin rippled, squeezing itself up out of the gully with a fast lurch. The caterpillar track held it steady on the soaking sulphur-yellow boltgrass that covered the slope. There was only a kilometer or so of desolate ground to cover before the unruly cloud base. They’d be a lot safer inside the thick, cool vapor.
The strategic assault display was empty now. Elan’s deployment was complete. The wormholes above the planet had all closed, shutting down the temporary communications feeds. Morton switched to a local display, checking the position of the other bubbles against his own. Unsurprisingly, Cat was already above cloud level, waiting for the rest of them. He fed power to the tread, and began his ascent.
The navy had been concerned that the snow that lay on the Dau’sing peaks all year round would leave tracks that the Primes could follow. For that reason the path preloaded into the bubble’s navigation array skirted the very high ground, taking Morton on a long winding route through tough passes and clinging to contour lines along alarmingly steep slopes. They need not have worried. The gray clouds were several degrees warmer and a lot muckier than the usual weather fronts besieging the mountains at the onset of the southern continent’s winter. The snowline had undergone a long retreat upward, exposing vast tracts of slatey shingle that hadn’t seen daylight for millennia.
Morton drove through the dark, murky fog for a couple of hours. He had to move slowly; visibility was down to thirty meters at best, and that was using the passive sensors on full resolution. All he saw was kilometer after kilometer of the same slippery, muddy shingle crunching below the translucent track. No other features emerged out of the fog. The angle of the slope changed, but that was it for variety.
They were traveling in a very loose convoy, with Cat out in front. At least he assumed she was still in front; he hadn’t spotted her beacon for over an hour and a half. She’d gone off at a speed he wasn’t going to try to match. Behind him, Doc Roberts was keeping a sensible kilometer separation distance. His beacon moved in and out of acquisition depending on the shape of the terrain.
Morton rounded a sharp vertical ridge of rock, and the Cat’s beacon was shining three hundred meters ahead.
“Where’ve you been, boys?”
“Taking care,” Morton said. “We’re not proving anything to each other here.”
“Touchy!”
He accelerated down the shallow incline to her bubble. She had stopped at the low point of a shallow saddle between a couple of peaks on the edge of the Regents range, about fifteen kilometers from where the navy detector station had been built. It was walled in on both sides by cliffs of sheer rock rising to vanish into the turbid clouds that occluded the peaks. The ground between them was a stratum of crumbling stones, scattered with fresh unsteady piles that had fallen from on high when the mountains were shaken by the nuclear blast.
Morton drove his bubble on a slow circuit of the area, matching up what they’d reviewed on the satellite imagery from CST’s original survey. It was a good location to adopt as a base camp. The cliffs were riddled with slim zigzag fissures and deeper crevices. He identified at least three where they could store the bubbles and equipment.
“This should do,” he announced as the Doc’s bubble came slithering down the incline.
“Well, as long as you think so, Morty darling,” Cat said.
Once everyone had arrived, they got out of the bubbles and started unpacking their equipment. Morton and Rob took a fast walk over to the edge of the saddle. Past the cliffs, the ground curved down sharply, though visibility was still only a few tens of meters. The clouds were moving faster here, scurrying along the southern edge of the Regents. Without them, Morton and the Doc would have had a clear view straight down to the Trine’ba two kilometers below. Randtown itself was away to the west.
“There’s a lot of activity down there,” the Doc said. He was using his suit’s electromagnetic spectrum sensors to scan the shoreline of the vast lake.
Morton switched on his own sensors. The clouds filled with a bright gold radiance, as if a small, intense star was rising from the Trine’ba. When he added analysis programs, the coronal hue changed to a serpentine mass of entwined emissions, bundled sinewaves thrashing in discord. As well as the strange Prime communications, there was the bolder background turquoise of powerful magnetic fields flexing in a slow cadence. Lavender sparks swarmed around the empire of light, flyers trailing their own wake of cadmium signals, their membranous force fields flickering like wasp wings. “What kind of important installation would you build in Randtown?” he asked out loud. “I don’t get it. There’s nothing here. Send your invasion force halfway across the galaxy so they can build a five-star ski resort? That’s crazy.”
“This whole invasion makes no sense,” the Doc said. “There must be something down there more valuable than we realized. They are alien, remember. Different values.”
“We understand their technology,” Morton countered. “They base everything on the same fundamental principles we do, they ain’t that different.”
“When you apply technology to a requirement it nearly always shakes down to a one-solution machine in the end: cars to travel over land, rockets to fly into space. But motivation, that’s a species variable, always has been.”
“Whatever,” Morton said. As well as his dodgy medical qualifications, the Doc had some obscure English degree dating back over a century; all that education made him want to overanalyze everything. “We’re not here to admire their psychology, we’re here to blow the shit out of them.”
“Eloquently put,” the Doc said.
Morton took out a type three sensor, a transparent disk five centimeters across, and stuck it on the side of a boulder where it could scan across the Trine’ba. “That’ll spot anything approaching us.”
“Unless they come from the other side.”
“We’ll place sensors all the way around our base camp. Obviously. It’s not like we’ve got a shortage of them.” Part of their mission procedure had them building up a comprehensive network of the optronic devices, allowing them to monitor all the alien activity in and around Randtown.
“Roger that,” the Doc said; he sounded amused.
They spent the next forty minutes scrambling over rocks and unstable shingle falls, planting the little sensors to provide early warning of any approaching flyers. Not once did they see sunlight; the cloud swirled and eddied as they clambered about, but it remained unbroken.
“Well done, boys,” Cat said as they arrived back at the base of the saddle.
“Great views you’ve given us; lots of rock and a big wet sky.”
“Let’s just hope it stays that interesting,” Rob said.
“That kind of depends on us,” Morton said. “We’re here to cause as much disruption as we can. I guess we’d better start by scouting out the neighborhood. We need two teams, and someone to stay up here to safeguard the equipment.”
“I’m sorry, sweetie, I must have missed that,” Cat said. “When did they pin a general’s star on you?”
“You don’t need to be a general to point out the bleeding obvious,” Parker said. “We know what’s on the mission plan. Establish a knowledge of the enemy and use it to hit them hard.”
“And the person staying behind ain’t going to be you, Cat,” Rob said.
