“There are hundreds of ready-made chambers in this complex alone,” Telgar said. He was unfolding the plassheet on which he and his beloved Sallah had recorded their investigations of eight years earlier. “There are at least four openings to the cliff top which could be used for air circulation. Channel down to water level and install pumps and pipe—I came across big reservoirs of artesian water. Core down to the thermal layer and, big as it is, the whole complex could be warmed in the winter months.” He turned back to the opening. “Block that up with native stone and this would be an impregnable fort. No safer place on this world during Threadfall. Further along the valley, there are surface-level caves near that pasture land. Of course, it would have to be seeded, but we still have the alfalfa grass propagators that were brought for the first year.

“At the time there was no need to investigate thoroughly, but the facilities exist. As I recall when we overflew the range above us, we discovered a medium-size caldera, well pocked with small cliffs, about a half-hour’s flight from here. We didn’t think to mark whether it was accessible at ground level. It might be ideal for dragon quarters, so accessibility isn’t a problem, provided they do fly as well as dragonets.”

“We seen a couple old craters like that,” Ozzie said, consulting the battered notebook that habitually lived in his top pocket. “One on the east coast, and one in the mountains above the three drop lakes, when we was prospecting for metal ores.”

“So,” Cobber began, having recovered from his awe, “the first thing is cut steps to this here level.” He walked to the edge of the cave and looked down critically at the stone face. “Maybe a ramp, like, to move stuff up here easy like. That incline over there’s nearly a staircase already.” He pointed to the left-hand side. “Steps neat as you please up to the next level.”

Ozzie dismissed those notions. “Naw, those Landingers will want their smart-ass engineers and arki-tects to fancify it for them with the proper mod cons.”

Cobber settled a helmet on his head and switched on its light. “Yeah, else some poor buggers get all closet-phobic.”

“Claustrophic, you iggerant digger,” Ozzie corrected him.

“Whatever. Inside’s safest with that farking stuff dropping on ya alla time. C’mon, Oz, let’s go walkabout. The admiral and the governor are counting on our expertise, y’know.” He gave an involuntary grunt as he settled the heavy cutter on his shoulder and strode purposefully toward the first tunnel.
