Moon twitched with the urge to hurry, but made himself wait for Jade. Chime groaned and said, “I hope I’m not wrong.”
Jade just growled in her throat and followed Malachite, and Moon, Chime, and Floret leapt after her.
Malachite had already circled over the island once and now dove down to land near the source of the waterfall. The foliage was so thick, Moon and the others had to land in the palms or ferny tops of the trees and clamber down. This surprised a number of large colorful tree crabs, which clacked their claws menacingly and skittered down the trunks, but Moon didn’t catch sight or scent of anything larger. There were traces of Fell stench on the leaves, caught when the Fell had brushed against them. He couldn’t pick out Shade’s more subtle scent.
The ground was covered with thick, low grass and flowers with heavy succulent stems. The waterfall was fairly narrow, only about twenty paces across at this point, and emerged from a slot in the bluff just above their heads. It tumbled across a mildly sloping space where there was barely room between the trees to walk, then dropped off the edge of a cliff to catch on another slope further down and disappear into the jungle again.
Malachite perched on a rock at the edge of the drop. “Floret, where did you search?”
Her voice blended with the falling water, pitched to cut through it but not be heard above it. Floret pointed toward the bluff. “Up there, because I thought they must have gone into a cave. But their scent was already faint.”
“As if they weren’t here long,” Jade said under her breath, and ducked under the low-hanging palms to scan the ground. Moon searched out from the waterfall, poking at the dirt under the grass and matted flower stems. The sea wind was blocked by the trees and the bluff, so if the Fell had lingered here at all, their scent should be much stronger. They didn’t just stop here briefly and leave, or Floret would have seen them. They might have climbed down through the jungle to the lower part of the island, but he thought the scent trails would indicate that.
Behind him, toward the waterfall, he heard Chime say, “This is fresh water. And that opening in the rock where it’s coming out is too square. Someone must have carved it.”
Moon started to turn back, but a flash caught his eye and he froze, focusing on it. It was a copper disk, lying amid the tree roots. Moon eased forward and picked it up. The incised image of a flower was clearly Arbora work and would have told him everything he needed to know, but he also recognized it. It had come off the anklet that Shade had been wearing.
He reached the waterfall again in a few long bounds, and held up the disk for Malachite to see. “Shade left a trail.”
They followed the path of scent traces and strategically dropped copper disks through the thick jungle. It led down the slope and around, toward the lower reaches of the rocky bluff behind the waterfall. Playing weak coddled young consort, Shade must have pretended to stumble and fall, long enough to snatch a handful of disks off the anklet.
Following the others through the greenery, Moon realized it might not have occurred to him to do the same in Shade’s position. Shade obviously took it as a given that Moon, or the warriors, or Malachite, or somebody would come after him, whether they arrived in time to save him or not. Moon would have just accepted the gut reaction that they would all think he was dead, dooming himself and leaving the queens no way to figure out where the Fell had gone and what they had been after. You have to work on that, he told himself.
The trail wound down through a nearly vertical gulley, shadowed by trees and heavy growth along its edge. The jungle was curiously quiet; insects hummed in the undergrowth but the birdcalls were distant, and Moon heard only a few rustles and clacks from the tree crabs. At the bottom of the gulley they went through a curtain of vines touched with Fell stench, and came out at the base of the rocky bluff that supported the waterfall.
For a moment it looked like a dead end. Then Moon realized the shadowed fold in the rock was a cave.
Jade reached it first and hissed with surprise. Moon arrived at her side in one bound, barely behind Malachite, with Floret, Chime, and Lithe after him.
It wasn’t a cave so much as an arch, curving to lead into an open well in the rock. In the well hung heavy chains supporting what had been a system of metal stairways, suspended out over the shaft. Several of them descended a hundred paces down to the deep shadowed entrance of a cavern at the bottom. Time and weather and maybe something else had broken a few of the chains and left some of the sections of stairway to hang in various precarious positions. They would have been unusable now by any species that weren’t skillful climbers. The verdigrised metal had been silvery at one point and chased with elaborate curling designs. An overhang shielded the shaft from overhead view, but let in daylight to gleam off the metal and the mineral streaks in the rock.
“So there were groundlings here at some point,” Moon muttered. It was another indication they were on the right track, but the right track to what?
Jade cocked her head to listen intently, and then tasted the air. “There’s seawater down there. But I don’t hear waves.”
Chime leaned out to look down the shaft. “So these were for bringing groundlings up from a harbor, somewhere down through there? But there’s nothing up here.”
Malachite caught one of the chains and swung out onto it. “The metal stinks of Fell,” she commented, and started to climb down.
Jade growled under her breath and sprang for another chain. “Floret, stay up here.”
Floret made a noise of protest in her throat, but quelled it at a dark look from Jade. Floret said, “If you don’t come back by nightfall, I follow you?”
“No, you find the flying boat and tell Stone what happened.” Jade began the climb down.
Lithe’s legs were a little too short to safely make the leap, so Moon leapt for a chain and then swung one of the others into her reach. She caught it and started down. With a worried shiver of his spines, Chime sprang after Moon. “At least we’re not in the sac anymore,” he said as they started down.
“Keep telling yourself that,” Moon said. He didn’t think the Fell had been called here by groundlings, even groundlings with the ability to get out to this island and construct these stairs.
“Be careful,” Floret said, leaning out to watch their progress.
They climbed down rapidly, following Malachite’s lead.
The opening to the cave was dank and cool, the air heavy with salt and the faint scent of rotting sea wrack. The sides were steep for some distance but then opened up gradually.
The chains stopped at a wide ledge in the wall, augmented by a rusted metal platform that had been attached to the rock with a complicated series of buttresses. Malachite already stood on it, and Jade dropped from the chain to land beside her.
Moon swung down off his chain, trying to take it all in. The faint daylight fell down on a series of ledges that stood out from the rock walls, studded by metal ladders, stairways, chains, all apparently designed to allow access further down into the cavern. Leaning out over the ledge, Moon saw dark water lap against rocks at the bottom. But he didn’t see any opening to the outside.
He also didn’t see, scent, or hear any sign of the Fell. They had apparently passed through this cavern on their way to somewhere else.
Lithe collected a couple of small rocks and concentrated until they emitted a soft glow of light. She handed one off to Chime to carry. Malachite leapt down to the next ledge, avoiding the rickety platform attached to it, and they followed her.
“There are carvings on these walls,” Jade pointed out, as she landed on another ledge.
