be a problem. River struck at its lower body and opened a gash across its stomach, and the creature barely noticed.
As Moon bounced back to a pillar and braced himself for another strike, Jade got in a rip across its throat, just above the decaying gills. That should have opened an artery, but it only released a short burst of foul-smelling fluid. It clawed at the wound and reached for Jade, forcing her to scramble back over its shoulder.
Moon saw that Balm clung to the ceiling carving just above, caught her eye, and pointed emphatically toward the creature’s head. Balm nodded, and Moon pushed off the pillar as she dropped from the ceiling. As Balm landed on the waterling’s head, Moon darted at its face, distracting it. Then Balm stretched down and raked it across the right eye.
The waterling roared, flailed its arms, and Moon twisted away only to run smack into a giant blue palm.
It slapped him out of the air. Instinct made him snap his wings in to protect them. Moon hit the paving in an uncontrolled tumble, and bounced to a halt to land on his back. The breath knocked out of him, he looked up to see the waterling’s big ugly face looming over him, one eye ripped open and leaking puss, the other filled with fury.
Then the waterling jerked back, roaring.
Moon shoved himself back and scrambled away, far enough to see Stone clamped to the creature’s back, his teeth and claws sunk deep into its flesh just above its spine. Then Stone twisted his head.
There was a muffled crack and the waterling stiffened, its tail lifted and fell with a thump that Moon felt through the paving. Then it slumped sideways, its body going limp.
Stone released it, spat in disgust, and jumped down off the creature’s back. The waterling was still alive, or at least animate. Its one working eye was still aware and furious, and its fingers twitched, though it couldn’t seem to move its arms. Moon took a deep breath in relief. He didn’t think they could have kept that up much longer. Jade and River glided down from the pillars to land at a safe distance, staring uneasily at the fallen creature.
Then from the dome, Chime shouted, “We’ve found a way in!”
Moon staggered upright. Chime had somehow managed to lift up the heavy figured metal of the sea serpent’s coil, next to the seam Balm had found earlier. Flower leaned down and pried at something hidden under the coil, while Esom tried to peer over her shoulder without getting poked by her spines.
Moon reached them just as Jade arrived, River limping after her. Chime said breathlessly, “This metal piece is on a hinge, see? And there’s a—”
“A place for a key.” Flower had found a slot in the smooth metal under the coil. The slot was meant for something round, with oddly-shaped projections; it did look like a keyhole.
Esom said, “But we don’t have the key. There might be some way to pick it.”
Flower stepped back to look at the foot of the dome where it fit against the floor. She straightened up and tapped the edge of the seam. “Stone, push on this. I think this is a separate piece that slides sideways.”
Stone leaned in, retracted his claws to plant his hands on the metal, and pushed. With a creak and a squeal of distressed metal, the whole section of the dome started to slide, slowly revealing a split at the seam that leaked dim white light.
They moved hastily back, and Jade pulled Flower away.
As the dome opened, they saw an empty room only half the size of the structure, lit by two hanging vapor-lights. The walls were covered with the now-familiar carvings of blue-pearl groundlings, discolored with age. In the center stood a broad waist-high plinth, the slanting surface set with polished crystals in various blues, greens, golds.
Flower stepped inside and moved toward the plinth. Esom hung back, telling her, “Careful. It could be dangerous.”
Moon leaned inside the doorway for a better look at the plinth. Metal plates set beside the crystals were covered with incised writing and figures. We didn’t know it, but this was what we were looking for. He said, “You know what that looks like?”
Chime nodded, almost bouncing with excitement. “The steering device of a flying boat.”
Stone braced himself and gripped the sliding panel more tightly. Apparently the mechanism wouldn’t allow it to stay open on its own. Jade stepped over the threshold, and said, “Steering?
