"Do you think she knew Ulven?"
"I don't know."
"Do you think she left with him?"
"I have no proof."
Nara put her hands on the table. "You say that as if you wanted me to believe you."
"I don't ask to be believed. I want to know if the name I saw can help you recognize its route."
Ilda intervened. "The salt path leads to several shelters. The watch station is not the only way out. If they crossed the door before it was sealed, they were able to reach the western galleries."
"When was the door sealed? Zaelyra asked.
Nara hesitated. "After Ulven's departure."
"Why?"
"Because the travelers who accompanied him had taken water and forced a room. We didn't know if they would come back. The council closed the road to prevent others from entering."
"You also closed the passage through which your son could have returned."
Nara's face hardens. "Yes."
"And did you know?" asked Kethra.
"I understood it later."
Neither of them added any consolation. Silence did not require the response to be softened.
Nara looked at Sarn. "When did you find the sheet?"
"She was already in the niche during the last inspection. I hadn't opened it."
"Why?"
"The red thread warned not to touch the cache."
"You respected the brand," says Nara.
"Yes."
"And then you let Zaelyra discover it."
"She didn't cross the thread."
Nara closed her eyes. When she reopened them, her look was more tired than suspicious. "We still don't know if this sheet comes from Ulven or Saira."
"No," says Kethra.
"But you want to continue to the west."
Kethra thinks. "I want to know if Saira has been here. I also want to follow the road. I don't know yet which of these two desires would make me change direction."
Zaelyra would have preferred her to choose now. That would have made the rest easier, and a clear answer would not have been more honest.
