"Get out of here," MacLean said. "This won't stop the bloody monster for long."

I didn't need urging, and raced past the wildly flailing creature.

MacLean grunted, impaling the rubbery blob. "That'll keep him for a bit."

"Can we kill him?" I asked.

The Scot grabbed my arm and dragged me after him. "If I knew how to do that, do you think I'd be running my bloody arse off?"

We ran through the maze of corridors for several minutes before MacLean made me stop, and looked me up and down for any sign of stray bits of the shape shifter.

I thought back to the incident. "How did you do that to him? I didn't think magic worked."

MacLean laughed. "That wasn't magic, lad. It was straight-up technology."

"It looked like a wand."

"Aye. It's called a cattle prod." He chuckled.

I felt my eyebrows rise. "A dinky old cattle prod stopped that thing? How did you know it would?"

"Research, lad. I've been stuck in the walls of the library for a bloody fortnight." He groaned. "Apparently, those nasty buggers conduct electricity almost as good as copper. Too bad it doesn't kill them."

After glancing up and down the hallway for any signs of suspicious children or extremely pissed off balls of dough, I decided it might be safe to return to the matter at hand. "Are you still okay with helping me in the Burrows?"

He snorted. "Might as well, since the Flark is temporarily taken care of."

I waved him onward. "After you."

MacLean led the way down a familiar flight of stairs until we reached the iron door guarding the tunnels where Bigglesworth had tortured MacLean. The big man didn't so much as glance down the hall toward the room, instead turned left and pointed out the iron grate with the hole I'd noticed the last time.

"What are we looking for?" the Scot asked, sending a globe of light into the passage.

"No idea. Whatever it is, I figure your Dark Sight should be able to pick it out."

We walked through the pitch black, the light sphere casting creepy shadows along the tunnel walls, eventually reaching a banded iron door. I pushed it open, the hinges squeaking ever so slightly, and light spilled into the corridor. Magic lanterns, similar to the ones I'd seen in other parts of the castle, lined the walls, their yellow glow offering a welcome respite from the smothering darkness of the previous passage.

MacLean snuffed his light, and we proceeded. Rusted gates, guard stations with levers to control the gates, shackles, and small cells with windowless doors offered a silent history of the dungeon. Unlike the winding corridors in the university complex above, the passages here formed a grid of stone-lined tunnels.

The tall Scot, a strained look on his face, said very little, but swept every crevice with his gaze, even going so far as to stop and look over each cell. I kept track of our progress with my phone, marking off passages as we went. As we reached the dead end of the final passage, MacLean squeezed his eyes shut, pinched the bridge of his nose.

"I've got a bloody headache," he said. "And not a thing to show for it."

Disappointment deposited a heavy load into my chest. "I was so sure you'd be able to see something."

He shook his head. "Sorry, lad. Didn't see a thing—well, except for a few nasty stains of magic here and there left from a particularly brutal execution or torture."

"Are you sure those couldn't have been the cause of the sickness?"

"Unlikely," he said, dismissing it with a shake of his head.

I sighed, and looked at the map I'd made. "I never saw anything like a gauntlet room either. Lina told me she'd been using one down here."

"A gauntlet room?" MacLean raised an eyebrow. "There's nothing down here but prison cells and guard stations."

I nodded. "And did you see any mattresses down here? Because Morgana told me she brought hers down." Biting my lower lip, I headed back up the passage toward the central section. "We must have missed something."

The big Scot blew out a breath, but kept pace even as he rubbed his temples. "Are you sure this is the right place?"

"Positive."

I stopped at the first guard station we came to, examining the small box of a room where one person could turn a wheel with chains wrapped around it to raise and lower the portcullis which blocked the only exit out of the section we were in. I tinkered with it, but rust held the portcullis in place, and it showed no signs of someone having opened it. We stepped into the original section of the dungeons, the central hub, and made our way toward one of the annexes. I suddenly wished I'd invited Zagg along.

"You look like you just tasted haggis for the first time, lad." MacLean squatted on a stone bench near a guard station. "I'm sorry, but I think we've done about all we can at this point."

I pulled out my phone and stared at it. "That's odd," I said, noting I had a signal. "We must be a mile underground, and I still have four bars."

"Aye, because we're right next to ley lines." He rubbed his forehead. "Or didn't you know that's how these phones work?"

"I didn't know." But it sure was handy. I called Cinder. He answered on the third ring. "Justin?"

"I'm in the Burrows," I said without preamble. "And I'm looking for a gauntlet room."

"I believe that would be Zagg's area of expertise. Please hold."

The sound of someone's fingers brushing across the phone preceded Zagg's confused voice. "Justin? Where are you?"

"Down in the Burrows."

"Why are you down there?" the historian asked, his voice full of concern. "That place is really dangerous."

"Well, there are these really sick kids, and…"

He sighed. "Give me a moment." I heard him say something indistinct which may or may not have included swear words, and Cinder replied in his calm voice. "Cinder is grabbing an ASE for me."

"I'll wait." As if I had a choice.

"Who are you talking to?" MacLean asked.

"Professor Zagg. He's a historian, and I hope he knows something about this place we don't."

"Aye, I know the man."

"There is a gauntlet room down there," Zagg said a moment later. "I remembered archiving a diagram of the Burrows a few years ago when I began my project to convert old texts to ASE format." He paused. "Which section are you in—no wait, better yet, have your phone send me coordinates."

"Nookli, send my coordinates to Cinder's phone."

"I will find all Indian restaurants and make the reservation, Justin," my phone replied after a moment.

I groaned, and repeated myself twice more until the phone did what I wanted while MacLean looked on with an amused expression.

Zagg made some thoughtful noises of his own as he did whatever he was doing on the other end, and then said, "Ah. You'll need to go to the guard station in the central hub, and head right. You can't miss it."

Obviously we had.

I jogged to the station, and looked right. A blank wall greeted me. "Zagg, there's nothing but a wall here."

"Unless the diagram is wrong, you should be standing at a door leading into another series of passages where the prison guards bunked."

MacLean furrowed his brow, staring at the wall for a moment before letting out a groan. "A bloody illusion." He regarded it for a moment longer. "And it's a recent enchantment."

I looked at the floor and noticed shoe scuffs and disturbed dust which cut off abruptly at the wall. I'm a horrible detective. I tentatively touched the wall, and felt only thin air. Poking my head through revealed an open door and another lit corridor. I went through with MacLean right behind, his eyes focused intently on our surroundings. We hadn't gone more than a few steps when I found the gauntlet room on the right. I turned to make a comment to MacLean when I saw him staring down the corridor.

He stalked down the hallway, muttering under his breath.

"What is it?" I asked, jogging to catch up.

"Bloody hell," he said, and stopped at the end. He touched the blank wall. Unlike the previous one, this one appeared real. He kicked at the stones, but they didn't budge.

I gripped his arm. "What are you doing?"

"There's something on the other side of the wall. It's pulsing like a bloody star."

He didn't need to say another word. I pressed a foot to the wall, and shoved, putting all my strength into it. Without warning, the wall caved in, and I almost tumbled in after it. A large slab of stone narrowly missed my head, and a cloud of dust sent MacLean and I coughing and backing away. When the dust cleared, a tunnel, this one obviously hewn from the mountain, lurked on the other side.

MacLean jogged down the narrow tunnel, as if drawn like a magnet. The illumination from the previous area dimmed to nothing, but light flickered from somewhere ahead, blindingly white one minute before dimming to ultraviolet. The Scot abruptly stopped, and I plowed into his back, rocking him forward on his feet.

"That's it," he said, pointing after he regained his balance, stepping forward into a wide chamber with walls of polished obsidian.

An Alabaster Arch sat in the center.

Chapter 36

The center of the arch crackled with a malevolent pulsar of energy which phased from white to ultraviolet as if a kid were playing with a sliding light switch on a wall. It hummed with the promise of death should anyone touch it, and teased the hairs on my arms with static.

The room wasn't very tall, perhaps thirty feet, and probably as wide and as long as a four-car garage. Not daring to take another step closer to the malfunctioning arch, I magnified my vision, examining its physical properties. I noticed something so odd, it took a couple of repetitions before I felt sure it wasn't my eyes playing tricks. As the white spectrum of light brightened, alabaster veins twined through the obsidian material of the arch, snaking through the material until it looked very similar to the Alabaster Arch I'd seen beneath Thunder Rock. But when the white light waned, the white veins faded until only black obsidian remained during the full power of the ultraviolet spectrum.
