The snow crunched beneath their boots as the team pushed forward, the silence of the mountain broken only by their labored breathing. Silas led the way, his eyes fixed on the distant peaks, the obsidian shard a cold weight against his thigh. The watcher’s echo had subsided after the cave, but it had not disappeared. It lurked at the edges of his consciousness, a predator waiting for the right moment to strike. Tenzin walked beside him, his staff marking a steady rhythm against the frozen ground. The former monk had not spoken since they left the cave, his face drawn and tired. Silas could see the weight of what had happened pressing on him, the knowledge that the threshold had nearly opened. “You said the sages will find us,” Silas said, breaking the silence. “How do we signal them?” “We do not signal them. They will sense our approach. The Seat of the Unseen is not a place you find by looking. It is a place you find by being ready to receive it.” “That’s not very helpful.” “It is not meant to be helpful. It is meant to be true.” Sarah fell into step beside them, her breath misting in the cold air. “I’ve been thinking about Cordelia. If she’s taking a different route, she might have information we don’t. She’s been studying the watcher for decades. She might know a way to bypass the Keeper of the Threshold.” “She might,” Silas said. “But she also tried to kill me at the Lake of the Moon. She’s not coming here to help anyone but herself.” “I know. But we should be prepared for the possibility that she arrives before us. If she reaches the Seat of the Unseen first, she could undo everything we’ve worked for.” “Then we make sure we get there first.” The trail began to climb, the switchbacks cutting into the side of a steep ridge. The snow was deeper here, reaching up to their knees in places, and the ponies struggled to keep their footing. Kowalski took the lead, his broad shoulders pushing through the drifts, while Patel covered the rear, her eyes scanning the ridges above. By late afternoon, they reached a narrow ledge that hugged the cliff face. The drop to the valley below was sheer, a dizzying expanse of white and gray. Tenzin stopped, his hand raised. “We rest here,” he said. “The pass is just beyond this ledge. But the path is dangerous, especially in the snow. We should wait until morning to cross.” Silas looked at the sky. The sun was beginning to set, casting long shadows across the mountains. The temperature was dropping rapidly, and the wind was picking up again. “We make camp,” he said. “But we keep watches. Two at all times.” The team set up a cold camp, huddling together for warmth in the lee of a rock outcropping. The ponies were tethered nearby, their breath steaming in the cold. Sarah passed around dried meat and energy bars, and they ate in silence, conserving their strength. Silas sat apart, the obsidian shard in his hands. He stared at its polished surface, seeing his own reflection distorted in its depths. The watcher’s echo pulsed, a steady beat that matched his heart. “You’re brooding.” Patel had moved to sit beside him, her rifle across her knees. She was a small woman, compact and precise, her eyes sharp and observant. “I’m thinking,” Silas said. “Same thing. Brooding is just thinking with a scowl.” He almost smiled. “I suppose you’re right.” “I usually am. It’s why I’m still alive.” She paused, her gaze fixed on the distant peaks. “I’ve been in a lot of bad situations. Iraq, Afghanistan, a few places that don’t have names. But this is different. This isn’t about politics or territory or revenge. This is about something I can’t see, can’t touch, can’t shoot.” “That bothers you.” “It terrifies me. But I signed up for this job because I believed in what you were doing. I still do. I just wish I understood it better.” Silas looked at her, seeing the weariness in her eyes. “I wish I understood it better too. Every time I think I have a handle on it, something new happens. The watcher is older than I can imagine, and it’s been waiting for a long time.” “For you?” “For anyone who could open the door. I just happened to be the one who walked through it.” Patel nodded slowly. “And now you have to close it.” “Yes.” “Then I’ll make sure you get there. That’s my job.” She stood, brushing the snow from her pants, and moved back to her position at the edge of the camp. Silas watched her go, feeling a small measure of gratitude for the people who had chosen to follow him into this madness. The night passed without incident, the cold a constant companion. Silas slept in short bursts, his dreams fragmented and uneasy. When dawn broke, the sky was clear, and the peaks of the Kunlun range were visible in the distance, their white caps catching the first rays of sunlight. “We move,” Silas said, his voice hoarse. “Today we cross the pass.” The ledge was treacherous, the snow hiding patches of ice that could send them plunging into the abyss. Tenzin led the way, his staff testing the ground before each step. The ponies balked at the edge, their eyes rolling, but Sarah’s steady voice coaxed them forward. They moved in single file, their breaths held, their focus absolute. The wind howled through the gap, threatening to tear them from the cliff face. Silas felt the watcher’s echo stir, a whisper of warning that made his skin crawl. *Careful,* the voice seemed to say. *The mountain is watching.* He shook his head, pushing the thought away. He would not let the watcher distract him. Not now. The pass was a narrow cleft between two massive rock formations, the wind funneling through it with a force that made standing difficult. Tenzin paused at the entrance, his eyes scanning the ground. “There are tracks,” he said. “Fresh ones. Someone passed through here recently.” “Cordelia?” Sarah asked. “Perhaps. Or perhaps the sages themselves. They move through these mountains like ghosts, leaving only footprints in the snow.” Silas knelt, examining the tracks. They were small, almost delicate, the prints of a person who moved with purpose. “How old?” “A day, maybe two. The snow has partially filled them in.” “Then we’re close. Let’s not waste time.” They pushed through the pass, the wind tearing at their clothes, the cold biting into their exposed skin. The trail descended on the other side, leading into a valley that was sheltered from the wind. The snow was deeper here, but the ground was more stable, and the ponies moved with renewed energy. As they descended, Silas felt a change in the air. The watcher’s echo grew quieter, as if it were being muffled by something. The obsidian shard in his pocket grew warm, then hot, and he pulled it out, staring at it. The surface was glowing, a faint, pulsating light that seemed to respond to something in the valley below. “Tenzin,” he said, holding up the shard. “What does this mean?” Tenzin’s face went pale. “We are close. Very close. The shard is reacting to the Seat of the Unseen. It recognizes its birthplace.” “Then we’re almost there.” “Yes. But be warned. The closer we get, the stronger the watcher’s influence will become. It will try to stop us, to turn us back, to destroy us. The Keeper of the Threshold is only the first of many tests.” Silas pocketed the shard, feeling its heat against his thigh. “I’m ready.” They continued down into the valley, the walls of the mountains rising on either side. The snow began to thin, revealing patches of bare rock and hardy shrubs that clung to the frozen earth. In the distance, Silas could see the outline of a structure carved into the cliff face—a series of windows and doorways that seemed to grow out of the stone itself. “The Seat of the Unseen,” Tenzin said, his voice filled with awe. “I never thought I would see it with my own eyes.” Silas stared at the monastery, his heart pounding. He had come so far, lost so much, and now the end was in sight. But even as he felt a surge of hope, the watcher’s echo stirred within him, a cold presence that whispered in the darkness. *You think you can silence me?* the voice said, deep and ancient. *I am the shadow of humanity’s ambition. I am the consequence of your sins. You cannot destroy me. You can only delay the inevitable.* “We’ll see,” Silas muttered, his jaw set. He turned to the others, their faces tired but determined. “We make camp at the base of the cliff. Tomorrow, we enter the Seat of the Unseen.” The team moved forward, the monastery looming above them, ancient and silent. The final test was about to begin.
