Sak chirped on his shoulder, terrified. Kokerlii, for once, had nothing to say.

“Every bird from every island…” Vathi said, putting it together. “They all come here, to this place. Are you certain?”

“Yes.” It was a thing that trappers knew. You could not capture a bird before it had visited Patji.

Otherwise it would be able to bestow no talent.

“They come here,” she said. “We knew they migrated between islands.… Why do they come here?”

Was there any point in holding back now? She would figure it out. Still, he did not speak. Let her do so.

“They gain their talents here, don’t they?” she asked. “How? Is it where they are trained? Is this how you made a bird who was not an Aviar into one? You brought a hatchling here, and then…” She frowned, raising her lantern. “I recognize those trees. They are the ones you called Patji’s Fingers.”

A dozen of them grew here, the largest concentration on the island. And beneath them, their fruit littered the ground. Much of it eaten, some of it only halfway so, bites taken out by birds of all stripes.

Vathi saw him looking, and frowned. “The fruit?” she asked.

“Worms,” he whispered in reply.

A light seemed to go on in her eyes. “It’s not the birds. It never has been … it’s a parasite. They carry a parasite that bestows talents! That’s why those raised away from the islands cannot gain the abilities, and why a mainland bird you brought here could.”

“Yes.”

“This changes everything, Dusk. Everything.”

“Yes.”

Of the Dusk. Born during that dusk, or bringer of it? What had he done?

Downriver, the nightmaw screeches drew closer. They had decided to search upriver. They were clever, more clever than men off the islands thought them to be. Vathi gasped, turning toward the small river canyon.

“Isn’t this dangerous?” she whispered. “The trees are blooming. The nightmaws will come! But no. So many Aviar. They can hide those blossoms, like they do a man’s mind?”

“No,” he said. “All minds in this place are invisible, always, regardless of Aviar.”

“But … how? Why? The worms?”

Dusk didn’t know, and for now didn’t care. I am trying to protect you, Patji! Dusk looked toward Patji’s Fingers. I need to stop the men and their device. I know it! Why? Why do you hunt me?

Perhaps it was because he knew so much. Too much. More than any man had known. For he had asked questions.

Men. And their questions.

“They’re coming up the river, aren’t they?” she asked.

The answer seemed obvious. He did not reply.

“No,” she said, standing. “I won’t die with this knowledge, Dusk. I won’t. There must be a way.”

“There is,” he said, standing beside her. He took a deep breath. So I finally pay for it. He took Sak carefully in his hand, and placed her on Vathi’s shoulder. He pried Kokerlii free too.

“What are you doing?” Vathi asked.
