The second answer came before we had decided what to ask.
It trembled in the basin while Aunt Seli was still setting down the lantern she had brought from home. Two pale points touched, separated, then touched again. Orivane warmed against my palm. The guide’s light leaned toward the water.
“Is that the Hollow?” I asked.
“I believe so,” the guide said. “The signal has changed since our last exchange.”
Vaust stepped away from the stair, where he had been waiting with Elder Tavar. “Changed how?”
The basin shivered. The two points went dark, and a thin blue line appeared between them. It held for the length of a blink, then broke into three small marks.
Rellin crouched beside the stone. “The roots have felt that.” He pressed his palm to the floor, listening. “They’re drawing inward.”
“Then we stop,” I said.
The blue marks faded at once. The roots beneath us eased. I had said it quickly, before anyone could ask whether the answer might be worth the risk. My fingers closed around Orivane, and the crystal’s warmth steadied beneath them.
The guide turned its glow toward me. “That was the correct limit.”
“I’m glad,” I said. “I still want to know what it meant.”
Pellune flew down from the upper stone and perched on my shoulder. “A good question can wait until the floor stops trying to listen with its whole body.”
Rellin straightened. “It’s calm now. We can try again, if we keep the call small.”
Aunt Seli moved the lantern farther from the basin. “We should decide what we’re asking before the light returns.”
I looked at the guide. It had come home to this circle, but part of its attention still seemed to be turned north. Orivane had answered the signal once and received an answer back. I wanted another message for it. I wanted the Hollow to say that the way was open, that we could go and find the rest of Orivane’s home. Wanting it did not make the circle able to give it.
“Could we ask whether the Hollow’s boundary is holding?” I said. “Only that. No route, and no invitation to open one.”
The guide’s light shifted over the water. “I can send that inquiry. The answer may be incomplete.”
“Then we’ll take an incomplete answer.”
Vaust rubbed a thumb over the empty place at his belt where he used to carry the black stone. “If the answer points north, we should not treat that as permission.”
“I agree,” I said.
Next
Nerisai and the witnesses will return to the Hollow to test whether its first threshold is still holding without opening the uncertain path beyond it.
We took our places around the basin. Aunt Seli stood beside me; Rellin kept his fingers on the rim; Pellune settled near the lantern, wings dimmed to a soft green. Vaust remained across from me, with Elder Tavar at his side. No one stood between me and the stairs.
I opened my hand beneath Orivane. “You can choose whether to answer again.”
“I choose to answer,” Orivane said. “I will use the same small pattern.”
The guide sank its glow into the basin. The water turned the color of a blue moth’s wing. The Hollow’s distant shape came slowly into view: a ring of stones, softened at the edges, with the faint signal still resting beside it.
Orivane sent its pattern. Three pale marks crossed the reflection and stopped at the far edge.
The answer did not come at once. I followed a tiny bubble as it travelled from one side of the basin to the other. When it reached the center, the signal at the Hollow brightened.
First came one point. Then a second. A third appeared beneath them, and the three made a small circle crossed by a fine line.
Orivane’s glow sharpened. “I know that arrangement.”
The guide held still above the water. “Can you identify it?”
“It is a boundary marker. A relay used it to report that its first threshold was holding.” Orivane paused. “It does not certify the path beyond it.”
The little mark stayed steady. The shape reminded me of the sign the northern relay had made, but smaller, as if the Hollow could only manage the first part of the message. I pressed my free hand to the stone rim. Its cold steadiness helped me keep from leaning closer.
“So the Hollow is safe?” Pellune asked.
“Only the threshold,” Orivane said. “The message says it is still holding. It says nothing about what waits past it.”
Aunt Seli’s mouth tightened. “That is more than we knew.”
“And less than we hoped,” Orivane said.
The answer held in the basin without drawing toward us. The roots stayed settled. For a little while, the circle gave us the gift of a message that did not ask us to follow it.
Then a new point appeared just outside the little ring.
It matched the first of Orivane’s marks. Another came beside it, then another. The reply was beginning to copy the pattern we had sent.
“Guide,” I said, “close the exchange.”
The guide withdrew its light. The blue reflection went dark, and the copy vanished with it. Rellin kept his hand on the rim until the roots stopped their faint inward pull.
“Was that the interruption?” I asked.
“I cannot be certain,” Orivane said. “It may have been a copied response. The signal began to repeat my pattern after the boundary mark arrived.”
The words made my palm feel suddenly too small to hold the crystal. I remembered the northern line learning the shape of our choices, one careful answer at a time. We had not given it a choice today. Still, we had shown it the sound of Orivane’s call.
Vaust came a step nearer, but stopped outside the stones. “Then we have our answer and our limit. The threshold is holding. The copying began after the message. We should not ask again until we can change how we listen.”
He spoke without the easy certainty he used when he wanted others to hand him a decision. His hands stayed empty. I found myself grateful for that, though I was not ready to trust the instrument he had once carried.
The guide floated above the basin. “We can preserve the boundary marker as a received signal. We cannot confirm the conditions beyond it.”
“Keep the marker,” I said. “Don’t keep calling for more.”
“Understood.”
Orivane’s light had gone faint at its edges. I knew the little sign was not a door. It was not even a promise of a door. But the message had come from the signal it had left behind, and that signal had answered with something it had chosen to send.
“Your old network knew how to say the first part,” I said. “It’s still there, trying.”
Orivane rested in the hollow of my hand. “Yes. It may have been waiting for a safer way to answer.”
“Can we make one?”
“I do not know.” It took a moment to answer. “But now we know the Hollow can report a boundary without opening it.”
The guide’s light moved across the basin, leaving the little ring of stones dark and ordinary again. “If you return to the Hollow, you can approach its first threshold together. I cannot guarantee the next one.”
Aunt Seli glanced at me. “We will have to decide whether returning is worth the uncertainty.”
I pictured the Hollow’s thin, waiting signal. The last time we had stood there, we chose the guide’s path and left Orivane’s signal behind. We could not change that choice by wishing. We could go back with the same witnesses, carry no route until we knew what the boundary allowed, and stop where the message ended.
“I want to go back,” I said. “Not to open the northern path. I want to see whether the first threshold still holds when we’re there.”
Rellin took his hand from the basin. “I can read the roots on the way. If they refuse us, we turn back.”
Pellune’s wings brightened. “A journey with a place to stop. I approve of those.”
Vaust gave a small nod. “I’ll go, if the group agrees. I won’t bring the black stone.”
The others looked to Aunt Seli. She did not answer for us. Instead, she asked each of us in turn, and waited for every voice. When the last answer came, she placed her lantern beside the stair.
The mark in the basin had told us where the Hollow’s promise ended. Tomorrow, we would walk until we found that edge for ourselves.
