Hermes spun around so fast he nearly lost his footing.
A figure stood at the far end of the corridor, half in shadow, perfectly still. The low torchlight caught the sharp angles of a familiar face.
Burning amber eyes. Fiery red hair.
The headmaster.
Hermes's heart was somewhere in the vicinity of his throat.
"Mr. Gaemond," he said. "It is past curfew. You are in a part of the castle that first year students have no business being in."
Hermes said nothing.
"Where were you going?" Roland asked.
The silence stretched between them.
He looked at the corridor behind him, which he had no confidence he could navigate even if he ran. He looked back at Roland.
"I'm running away," he said.
Roland studied him for a long moment.
"Come," he said. "Walk with me."
They walked in silence for a while, the headmaster setting a measured pace through corridors that Hermes could not have found on his own. Roland seemed to know where every torch was and moved through the shadows between them with the ease of someone who had walked these same routes many times.
"You've been taking patrols," Hermes said eventually. It came out more like a question than a statement.
"Since the morning after you came to my office," Roland confirmed. "I believed your… vision warranted precaution, even if I chose not to say so at the time."
Hermes absorbed that.
"You believed me."
"I believed something," Roland said carefully. "Whether you are a seer or something else entirely is a question I have not yet resolved. But the details you described were specific and consistent and you had no obvious reason to fabricate them." He paused. "I simply saw no value in telling you that."
"Because you didn't want to cause a panic."
"Because you are eleven years old and already showing signs of causing quite enough disruption without additional encouragement." He glanced sideways.
"Professor Abano visited my office this evening as well. She presented a rune divination reading."
Hermes said nothing.
"It matched your vision with considerable precision, I found it difficult to dismiss."
So she went, Hermes thought. Of course she went.
He thought about her face when she looked at those runes. The way she had stopped arguing and simply stared.
He said nothing.
"The gray fog," he said after a moment. "I saw it part in my vision. Played in reverse it looked like it was rushing in to cover everything but if the whole vision was revealed to me reversed, the opposite would mean it was parting. Being broken." He paused. "The sun rose and set three times through the fog. That means—"
"That the protection will fail within three days from the point your vision began," Roland said. "Yes. I reached the same conclusion." He was quiet for a moment. "Tonight is the second night."
The words settled in his stomach like cold water.
"Then why," Hermes said carefully, "are you walking calmly through corridors instead of preparing?"
"Because I have been preparing," Roland said, "for two days."
He stopped walking.
They were standing at a large archway that opened onto a courtyard. Beyond it Hermes could see the castle gate, heavy iron, ancient, set into a wall that disappeared into darkness in both directions. And carved into the stone around the archway, following the curve of the wall as far as he could see in either direction, were runes.
Countless of them. Carved deep into the stone, running in chains, linking one to the next in a continuous unbroken array that circled the entire castle.
Hermes stared at them.
Through Oculus Sapientiae they bloomed open like a page turning , Protection, Abundance, Magnitude, Barrier, Shield, Permanence, Hold. Over and over, interlocking, each rune reinforcing the next, the whole array forming something that was greater than the sum of its parts by an order of magnitude he couldn't quite calculate.
"It has not been activated," Roland said, watching him. "The gray fog concealment spell has served as Chaldera's primary protection for nearly three thousand years. This array was carved as a secondary measure, generations ago, and has never been needed." He looked at the runes. "Until now."
"Then activate it," Hermes said.
"It requires the combined soul essence of half the faculty simultaneously," Roland said. "A considerable undertaking. I have prepared the staff. We are ready." He looked at Hermes. "What I have not done is tell the students. Because children who are told that monsters may attack their school tonight tend not to sleep, and a school full of frightened sleepless children is not a situation that improves anyone's odds."
Hermes looked at the runes carved into the stone, Protection, Abundance, Magnitude, Barrier, Shield, Permanence, Hold, running away into the darkness in both directions, waiting.
"You should have told me," he said.
"You were doing quite well on your own," Roland said, with something that might have been dry amusement in another context. "Standing on dining tables."
"Ugh… You heard about that." Hermes croaked a strange sound.
"Mr. Gaemond, I hear about everything."
Hermes looked at the gate. Beyond it was darkness and the hillside and somewhere out there thirty three monsters and a skeletal figure who was in the process of breaking a three thousand year old protection spell.
He thought about running. He measured the distance to the gate, the weight of the darkness beyond it, the complete absence of any plan for what he would do once he was on the other side.
And then what?
"If the array holds," he said slowly, "and the monsters still get through somehow, what then? I didn't see this array in my vision. How can I be certain it will hold against whatever broke the gray fog?"
Roland was quiet for a moment. Then he turned and gestured for Hermes to follow.
They walked to a tower at the far edge of the courtyard, narrow, unremarkable, the kind of structure that blended into the castle's architecture so completely you could walk past it a hundred times without registering it. Roland pushed open the door and they stepped inside.
A stone staircase spiraled upward into darkness.
And at the base of the first step, carved into the stone with the same clean precision as the runes outside, was a single inscription.
Hermes crouched and looked at it through Oculus Sapientiae.
Passage. Threshold. Journey. Chance. Uncertainty. Hidden things.
"Pour a small amount of soul essence into it," Roland said from behind him.
"I don't know how," Hermes said. "I only know the method for activating runes one at a time."
"The method is the same," Roland said. "Placing your palm against the carving is simply to help you feel the inscription and clarify your intent. Here the inscription is a single array, place your hand in the centre and pour in a small amount of soul essence with the intent to activate all the runes together. That is all."
That's it?
Hermes pressed his hand flat against the carving and did so.
The floor dissolved beneath him.
"Huaah!" Hermes yelped.
He dropped, not far, not violently, more like sinking through something that had briefly decided not to be solid, and landed on his feet in cool darkness. He looked up. The tower floor was above him, intact and unbroken, as though nothing had happened.
He was standing in a cave.
It stretched away from him in both directions, the ceiling low and rough, the walls close. The smell of cold stone and deep earth. Somewhere ahead the faint suggestion of moving air.
A moment later Roland dropped through beside him with considerably more composure.
"The cave system runs beneath the castle and emerges half a mile east of the hillside," Roland said quietly. "It has been here longer than Chaldera itself. Only the faculty and now you are aware of its existence."
Hermes looked at the darkness stretching ahead of him.
Half a mile east of the hillside. Away from the monsters. Away from the castle. A clean exit that required nothing but knowing where to go.
He stood there for a long moment.
"You're showing me this," he said slowly, "because you want me to stay."
"I am showing you this," Roland said, "because you deserve to make an informed decision. If you choose to leave tonight I will not stop you. The exit is ahead and to the left where the cave splits." He paused. "But I would prefer you stayed."
"Why?"
Roland considered the question with the careful honesty of someone who didn't give answers they didn't mean.
"Because whatever you are, Mr. Gaemond, you are not ordinary. And Chaldera has need of people who are not ordinary." He looked at Hermes in the dim light. "Also Professor Abano would be insufferable if you left."
Hermes almost laughed.
He stood in the cave beneath the castle with the exit to his left and the staircase behind him and thought about Abano's face when she looked at those runes. Roland walking these corridors every night in silence. The runic array carved into the stone above him, waiting.
"I want your word," he said. "That you will protect every student in this castle."
"You have it," Roland said without hesitation.
"And if the array fails—"
"Then we use this," Roland said, gesturing at the cave around them.
Hermes looked at the darkness to his left for a moment longer.
"If the barrier fails," he said, "I am going straight to this tower."
"Of course," Roland said. A quiet amusement had entered his voice. "Though I do not anticipate it will come to that. Seven faculty members are stationed at the array as we speak, ready to activate it within five breaths. Another seven stand ready to relieve them. I was on my way there myself when I found you." He paused. "In the unlikely event the barrier does fail, the remaining faculty will begin evacuating all two hundred and ten students immediately. Of that I give you my word."
Hermes was quiet for a moment.
"But my vision," he said. "The barrier wasn't activated in it. The castle was destroyed."
Roland sighed not dismissively but with the weight of someone who had been thinking about the same thing for two days.
"I believe your vision came to pass because we were unprepared. Caught by surprise, most likely, the gray fog broken before anyone realised what was happening, the attack following before we could respond. But we are not unprepared now." He looked at Hermes steadily. "Mr. Gaemond, you changed that."
Hermes stood with the exit to his left and Roland's words settling around him in the dark.
Then he turned right.
They climbed back up through the floor into the tower and walked back into the castle together, the gate receding behind them, the carved runes watching them go.
