They had been descending for twenty minutes when the cloud closed behind them.
It came in fast. One moment the plateau was behind them and the ridge above was visible in patches of grey. The next, the trail ahead was a soft blur and the trail behind was gone entirely. Vane stopped and waited for the others to close up. He could hear Brandt's chain clinking against his hip, but he couldn't see him.
"Ten paces," Vane said. "No more."
"Understood," Brandt said.
"Vale?"
"Here."
Vane started down.
---
The route was worse going down.
The scree shifted under every step. Twice Vane had to stop and wait while Brandt anchored the chain so they could cross a section where the trail narrowed against the slope. The blazes were impossible to see in the cloud. Vane counted them from memory. Three behind them. The fourth should be forty yards ahead.
He counted steps instead.
Twenty. Forty. Sixty.
The fourth blaze should have been right there.
He stopped.
"Brandt."
"What."
"Blaze four."
Brandt came up beside him. He looked at the rock face. He ran his hand along it.
"Not here," he said.
"It should be."
"It's not."
---
Vale spoke from behind them.
"It's above us."
Vane turned. "What?"
Vale was standing still on the trail, head tilted. He wasn't looking at the rock face. He was looking at the cloud.
"Something moved," he said.
"Rockfall?"
"No. Slower than that."
Nobody said anything for a moment.
Vane listened. The cloud swallowed sound the same way it swallowed everything else — muted, close, directionless. He couldn't hear anything above them. He couldn't hear anything anywhere.
"Keep moving," he said.
They kept moving.
---
They made it another hundred yards before Vale stopped again.
"Vane."
"What."
"Don't move."
Vane froze.
The cloud was still. Brandt was still. Vale was still. Nobody breathed.
Then Vane heard it — a single stone, small, dislodged from somewhere above them and rolling down the slope. It passed to their left and disappeared into the cloud below.
Then another.
Then nothing.
---
"Something's on the trail," Brandt said quietly.
"I know."
"Above us."
"I know."
Vane reached for his field knife. It wasn't the right weapon for anything larger than a man, but it was what he had. Brandt had already unspooled a length of chain from his hip — not the survey chain, the shorter one, the one he carried for anchoring loads. He doubled it in his hand.
Vale hadn't moved. He was still standing on the trail, looking up into the cloud.
"Vale," Vane said. "Knife out."
Vale pulled his knife. He didn't look at it.
---
It came from above.
Not fast. Not dramatic. It dropped from the cloud onto the trail six feet in front of Vane, landed on all fours, and stood up.
It was about the size of a man. Low, dense, three-toed feet splayed wide for grip. Its hide was dark grey, coarse, matted with old mud. No visible eyes. No obvious head. Just a low, forward-leaning body and a mouth that opened along the front of it, wide and wet and full of small teeth.
It didn't roar. It didn't charge.
It stood on the trail and waited.
Vane understood immediately. It wasn't attacking him. It was blocking the route.
---
"Down," he said.
Brandt didn't ask what he meant. He dropped the chain and stepped backward, clearing the trail. Vane stepped left, into the rock face. Vale stepped right, toward the slope.
The creature turned its body to follow Vane.
Vane didn't move his feet. He focused instead — the same narrow spike of Ki he'd used on the granite-hide, condensed at the tip of the blade, razor-thin. He drove the knife into the shoulder joint.
The blade went in. The Ki went with it.
The creature flinched. It swung its head toward him. It wasn't fast, but it was heavy, and the swing carried enough weight to knock him off balance.
He caught himself on the rock face.
The creature was still standing.
Not dead. Not even slowed. The strike that had killed a granite-hide in a single motion had landed cleanly and barely slowed it.
Different anatomy. No soft membrane under the joint. No shared weakness.
Vane understood, in that half-second, that he was using the wrong technique on the wrong creature.
---
Brandt moved.
He came in from the side, chain doubled in both hands, and looped it around the creature's front leg. Then he planted his boots and pushed Ki down through his heels — the same anchor he'd used to drive the survey pin into slate.
The creature pulled.
Brandt didn't move.
The chain went taut, the creature's step turned into a stumble, and it was the stumble that broke — not the anchor. Brandt held the leg, and the creature had to catch itself on three feet to stay upright.
Vane used the half-second.
He drove the knife in again, higher, at the base of the neck — where the skin looked thinnest. Same technique. Ki spike. The blade went in deep. The creature made a sound that wasn't a roar. Something lower. A wet grinding noise from somewhere inside it.
It turned back toward Vane. It was still standing.
Brandt was still holding the chain.
---
Vale was standing at the right edge of the trail, knife out, looking at the creature.
Then he looked up, into the cloud, and stopped.
He held his hand out. Nothing moved. No angle, no surface, nothing to work with.
"Can't see it," he said. "Nothing to bend."
"What?"
"The light. There's nothing—" He stopped. Started again. "I can't do anything with this."
Vane didn't ask him to clarify. The creature was turning.
---
Vale spoke again, a second later. Quieter. Not looking at the cloud anymore — looking at the creature's feet.
"Its back foot doesn't load."
Vane didn't understand immediately.
Then he saw it. When the creature shifted its weight to turn, the rear left foot barely touched the ground. It was putting everything on three legs. The fourth was doing almost nothing.
"Break the turn," Vale said.
Vane didn't ask why. He moved to the creature's rear left side, away from the direction it was trying to turn, and drove the knife into the tendon above the useless foot.
The blade stuck.
He didn't have time to pull it free. The creature dropped — not fully, catching itself on its front legs — and the knife went with it, still buried in the tendon.
Vane let it go and stepped back.
The creature couldn't turn anymore. It couldn't block the trail. It couldn't follow them.
Vane looked at his empty hand. Then at the knife, still in the creature's leg.
He didn't try to get it back.
"Go," he said.
They went.
---
They didn't stop running until the scree turned back into slate and the blazes reappeared out of the cloud. Vane counted them. Three. Then two. Then the shelf, and the honest ground below it, and the tree line.
They didn't stop until they were back on the wildlife trail.
Brandt dropped the chain. His hands were shaking. Vale was breathing hard. Vane was still looking at his empty hand.
Nobody said anything for a long moment.
Then Brandt spoke.
"What was that."
Vane looked back up the ridge. The cloud had closed the trail entirely. Nothing was following them.
"I don't know," he said.
---
He opened the ledger that night, in the secondary shelter at the base of the ridge.
He wrote down what he knew. Three-toed creature. Approximately man-sized. No visible eyes. Primary sensory mechanism unknown. Movement appeared slow but carried significant force. Blocked the trail rather than chased. Didn't pursue after breaking contact.
He wrote the next line and stopped.
Condensed Ki strike ineffective at shoulder joint. No soft membrane. Anatomy does not match granite-hide vulnerabilities.
He read it back. He'd used the same technique he'd used on the Eastern Spur. The same technique that had killed a granite-hide with a single upward thrust. Here it had landed clean and done nothing.
He didn't know what that meant yet. He wrote it down anyway.
Left behind: one field knife, buried in the left rear tendon.
He turned the page. He wrote a new line.
Not signs of use. Occupied.
He looked at it for a moment.
Then he closed the ledger and went to find Brandt.
