"The chokers are native to Tober," Gwen said. "They're taking over the forests here, just as they did there. We could have told them it would happen, but they wouldn't have cared. The forests were all doomed anyway, even before they were planted. Even the chokers will die, though they'll be the last to go."

They walked on, and the chokers grew steadily thicker, until soon they dominated the forest. Here the woods were denser, darker; passage was more difficult. Half-buried roots tripped them underfoot, while tangled branches interlocked above them like the straining arms of giant wrestlers. Where two or three or more chokers grew close together, they seemed to merge into a single twisted knot, and Gwen and Dirk were forced to detour. Other plant life was scarce, except for beds of black and violet mushrooms near the feet of the yellow trees, and ropes of parasitic scumweb.

But there were animals.

Dirk saw them moving through the dark twistings of the chokers and heard their high, chittering call. Finally he saw one. Sitting just above their heads on a swollen yellow branch, looking down on them; fist-sized, dead still, and somehow-transparent. He touched Gwen's shoulder and nodded upward. –

But she just smiled for him and laughed lightly.

Then she reached up to where the little creature sat and crumpled it in her hand. When she offered it to Dirk, her palm held only dust and dead tissue.

"There's a nest of tree-spooks around," she explained. "They shed their skins four or five times before maturity and leave the husks as guards to scare away other predators." She pointed. "There's a live one, if you're interested."

Dirk looked and caught a fleeting glimpse of a tiny yellow scampering thing with sharp teeth and enormous brown eyes. "They fly too," Gwen told him. "They've got a membrane that goes from arm to leg and lets them flit between the trees. Predators, you know. They hunt in packs, can bring down creatures a hundred times their size. But generally they won't attack a man unless he blunders into their nest."

The tree-spook was gone now, lost beneath a labyrinth of choker branches, but Dirk thought he saw another, briefly, from the corner of his eye. He studied the woods around him. The transparent skin husks were everywhere, staring fiercely into the twilight from their perches, all small grim ghosts. "These are the things that get Janacek so upset, aren't they?" he asked.

Gwen nodded. "The spooks are a pest on Kimdiss, but here they've really found their element. They blend perfectly with the chokers, and they can move through the tangles faster than anything I've ever seen. We studied them pretty thoroughly. They're cleaning out the forests. In time, they would kill off all the game and starve themselves to death, but they won't have time. The shield will fail before that, and the cold will come." She moved her shoulders in a tiny weary shrug and rested her forearm on a low-drooping limb. Their coveralls had long ago become the same dirty yellow color as the woods around them, but her sleeve slid up and back as she brushed the branch, and Dirk saw the dull sheen of jade-and-silver gleaming against the choker.

"Is there much animal life left?"

"Enough," she said. Pale red light made the silver strange. "Not as much as there used to be, of course. Most of the wildlife has deserted the homeforest. Those woods are dying, and the animals know it. But the outworld trees are sterner, somehow. Where the forests of the Fringe were planted, you'll find life, still strong, still hanging on. The chokers, the ghost trees, the blue widowers-they'll flourish right until the end. And they'll have their tenants, old and new, until the cold comes."

Gwen moved her arm idly, this way and that, and the armlet winked at him, screamed at him. Bond and reminder and denial, all at once, love sworn in jade-and-silver. And he had only a small whisper-jewel shaped like a tear and full of fading memories.

He looked up, past a wild crisscross of yellow choker branches, to where the Helleye sat in a murky slice of sky, looking more tired than hellish, more sorry than satanic. And he shivered. "Let's go back," he told Gwen. "This place depresses me."

He got no argument. They found a clear spot away from the chokers that pressed around them, a place to spread the silver-metal tissue of their scoots. Then they rose together for the long flight back to Larteyn.

They raced again above the mountains, and Dirk did better this time, losing by less than he had before, but the improvement did not lighten his mood. For most of the weary trip they flew in silence, apart, Gwen meters ahead of him. Their backs were to the broken, muted Wheel of Fire as they went, and Gwen was a witch figure vague against the sky and always out of reach. The melancholy of Worlorn's dying forests had seeped into his flesh, and he saw Gwen through tainted eyes, a doll figure in a suit as faded as despair, her black hair oily with red light. Thoughts came in a colored chaos as the wind swept past him, and one more often than the others. She was not his Jenny, was not and never had been.

Twice during their flight Dirk saw-or thought he saw-the jade-and-silver flashing, tormenting, as it had tormented him in the wood. He forced his eyes away each time and watched black clouds, long and thin, skitter across the barren, empty sky.

The gray manta aircar and the olive-green war machine were both gone from the rooftop lot when they reached Larteyn. Only Ruark's yellow teardrop was unmoved. They landed nearby-Dirk's landing yet another clumsy stumble, now oddly humorless, only stupid-and left the sky-scoots and flight boots out on the roof where they removed them. Near the tubes they spoke briefly, but Dirk forgot the words even as he said them. Then Gwen left him.

In his rooms at the base of the tower, Arkin Ruark was waiting patiently. Dirk found a recliner amid the pastel walls and sculpture and the potted Kimdissi plants. He reclined, wanting only to rest and not to think, but Ruark was there, chuckling and shaking his head so the white-blond hair danced, thrusting a tall green glass into his hand. Dirk took it and sat up again. The glass was a fine thin crystal, plain and unadorned except for a fast-melting coat of frost. He drank, and the wine was very green and cold, incense and cinnamon down his throat.

"Utter tired you look, Dirk," the Kimdissi said after he had found a drink of his own and seated himself with a plop in a slung-web chair beneath the shadow of a drooping black plant. The spear-shaped leaves cast striped darkness on his plump, smiling face. He sipped, sucking the drink noisily, and very briefly Dirk despised him.

"A long day," he said noncommittally.

"Truth," Ruark agreed. "A day of Kavalars, heh, always long. Sweet Gwen and Jaantony and last Garsey, enough to make any day last forever. What do you say?"

Dirk said nothing.

"But now," Ruark said, smiling, "you have seen. Me, I wanted that, for you to see. Before I told you. But I was sworn to tell you, yes, a swearing to myself. Gwen, she has told me. We talk, you know, as friends, and I have known her and Jaan too since Avalon. But here we've grown closer. She cannot talk of it easily, ever, but she talks to me, or has, and I can tell you. Not violating trust. You are the one to know, I think."

The drink sent icy fingers down into his chest, and Dirk felt his weariness lifting. It seemed as if he had been half asleep, as if Ruark had been talking for a long time and he had missed it all. "What are you talking about?" he said. "What should I know?"

"Why Gwen needs you," Ruark said. "Why she sent… the thing. The red tear. You know. I know. She has told me."

Suddenly Dirk was quite alert, interested and puzzled. "She told you," he began, then stopped. Gwen had asked him to wait, and long ago the promise he had made-but it fit. Perhaps he should listen, perhaps it was simply hard for her to tell him. Ruark would know. Her friend, she had said in the forests, the only one she could talk to. "What?"
