"You mean to go through with your plan?" Benjin asked as they huddled against the icy winds.

"I don't know. I have to at least try to destroy the statue before it detonates, which is most likely suicide, but what other course of action could I take and keep a clear conscience?"

"We will just have to deal with the details along the way. We'll find some way to overcome the obstacles, you and I. We always do." His words offered Catrin a small amount of comfort, and she leaned on him as they walked. So many times he had been there for her; she did not know what she would do without him.

Captain Longarm was not in the guardhouse when they arrived, but another guard retrieved their weapons and returned the parchment to them. Benjin handed Catrin her knives and grabbed his own knife and sword. The rest he asked the guard to return to storage, and with that, they departed for the Inner Sanctuary.

Brother Vaughn looked nothing like himself when they returned. He was dressed in leathers with picks and hammers dangling from his belt. He wore a sturdy leather cap and gloves, and he slung a pack over his shoulder as they entered. Two more packs, near to overflowing, sat in a corner. Catrin and Benjin needed no prompting, and they shouldered the packs. Catrin stood with her staff in hand, trying to be confident, but her knees shook. This was perhaps the most dangerous parting yet.

"There is no time to waste. We must leave at once," Brother Vaughn said, but he stopped to flip through a book that contained charts and drawings of the moon.

"I must beg a favor of you," Catrin said. "I have a mission for Chase that requires him to depart after the ascension. Will you guide him?"

"It won't be easy. The rites of ascension are long and will require much of my time. I cannot abandon my responsibilities at such a crucial time, but I will find a way to accomplish it."

Catrin nodded her thanks, aware she was asking a great deal of him, and also knowing he would keep his word regardless of the cost. She was glad he did not downplay the inconvenience; she valued his honesty, even if it did make her feel guilty. It was preferable to pretty lies.

Brother Vaughn led them to the main stairwell, and they descended to its base, where the air was icy and dank. Lanterns had been left for them, and only the light they shed kept the darkness at bay. From his pocket, Brother Vaughn retrieved a small sand clock, which he turned over and put back in his pocket.

The rough-hewn tunnels beneath Ohmahold often intersected with other tunnels and passages. After only a few turns, Catrin was completely lost. Several times, they passed monks working in the mines, using mules to pull cartloads of salt and ore.

"Much of our livestock is born and bred within the mines," Brother Vaughn said. "It saves us the need to hoist the animals, and it also provides a secure food source in the event of a siege. We've water, salt, ore, and, in some cases, light, all within the mining complexes. But until recently, there has only been one way in or out of the mines for the sake of security. Only when the salt miners tunneled into an existing mine did we realize the ancient complex even existed."

"What about the place where we will exit the mines. Is it well hidden?" Benjin asked.

"Extremely," Brother Vaughn replied as he checked his sand clock. "We need to move faster," he said as he strode ahead of them.

Most of the tunnels looked exactly alike, rough-hewn rock supported by wooden buttresses and joists. The wood was treated with creosote and kept in good condition, but Catrin still felt like the mountain might crush her under its weight.

After what seemed like a day of walking, they reached a rough section of tunnel that ended in an oblong breach.

"This shaft leads to the ancient mines, but it is quite a drop to the floor below. Take care when you enter," Brother Vaughn said as he climbed through the opening. Benjin followed, and Catrin heard his low whistle when he reached the floor. She handed her staff down to him, and she dropped through the orifice. The fall was farther than she anticipated, and she landed hard, knocking the breath from her.

The floor on which she lay was cut into geometric patterns, and though covered with grime, they were still a marvel. The tunnel dwarfed those recently mined. The walls were cut smooth and straight, and the ceiling was lost in the darkness. Evenly spaced arches supported the tunnel, and they were carved with images of trees and flowers. Some bore images of wildlife, but no human forms were present. Catrin dusted herself off and turned in a full circle, taking in the majesty of the place.

Brother Vaughn did not give her long to enjoy the sights, though, as he set off at a brisk pace after once again checking his sand clock. The floors were level and the tunnels free of debris, which made for easy traveling. Intersections came and went, but Brother Vaughn gave them scarcely a glance as he passed them. The only indication that he noticed them at all was his mumbled count incremented at each one. When he reached what Catrin thought was the twelfth nearly identical intersection, he turned right.

The turn made Catrin feel they had made progress, and she fooled herself into thinking the journey was near complete. It seemed impossible that the mines could go on much farther, and the monotony of it played tricks with her mind. When Brother Vaughn called for a rest, Catrin had no idea how long they had been walking. Time seemed to lose meaning beneath the land, and Brother Vaughn's desire to keep track of the hours was starting to seem more reasonable.

They ate in silence, each consumed with his or her own thoughts. The salted beef satiated Catrin's hunger, but her spirit was restless. She missed the sun and stars, and though they had been in the mines only a short time, she felt separated from Istra's energy. The lack of power made her feel vulnerable, and she pulled the noonstones from the gilded box. They felt wonderful in her hands. She rolled them in her palm and let them soothe her, not drawing any of the energy they held in reserve; instead, she just basked in their existence and the security they gave her.

An enormous arch loomed in the distance. Like the gates to a dark dimension, it was guarded by a multiheaded serpent whose fangs dripped with venom. Though carved from stone, it was a fearsome sight, and Catrin was loath to enter such a mystical portal. Brother Vaughn paid it no mind, and the serpent did not strike him as he passed through, but Catrin felt the reptilian stare intensely, and she had a vision of the beast coming to life. It was almost as if the carvings spoke to her: "Your descendents will pay dearly for your trespass," said the vision. Catrin shivered as if it were a premonition rather than the conjuring of her frightened mind. Benjin seemed troubled as well, and he looked over his shoulder frequently, which drove Catrin to do the same. She felt as if she were an intruder, and she half expected an army of ancients to descend upon them.

Beyond the intimidating arch lay a domed room that seemed impossibly large. Every part of the walls, with the exception of periodic archways, was carved to resemble a forest, and the detail boggled the mind. It was as if she stood in the center of a grove of stone, where each leaf, branch, and trunk was a masterpiece. Birds soared through the skies, and butterflies rested on rose petals. Even without motion, the enormous waterfall seemed alive, so clever was the craftsmanship.

"I would speculate these mines were in use for at least a thousand years," Brother Vaughn said, seeing the looks of awe on their faces. "I do not see how such mastery could have been achieved in any shorter span of time."
