“What is this place?” I asked as we slowly made our way through.

“It was originally a pilgrimage site, back when Ravka’s borders extended farther north,” Nikolai replied. “The Monastery of Sankt Demyan.”

Sankt Demyan of the Rime. At least that explained the winding staircase we’d glimpsed. Only faith or fear could get anyone to make that climb. I remembered Demyan’s page from the Istorii Sankt’ya. He’d performed some kind of miracle near the northern border. I was pretty sure he’d been stoned to death.

“A few hundred years ago, it was turned into an observatory,” Nikolai continued. He pointed to a hulking brass telescope tucked into one of the glass niches. “It’s been abandoned for over a century. I heard about it during the Halmhend campaign, but it took some finding. Now we just call it the Spinning Wheel.”

Then it struck me: the bronze columns were constellations—the Hunter with his drawn bow, the Scholar bent in study, the Three Foolish Sons, huddled together, trying to share a single coat. The Bursar, the Bear, the Beggar. The Shorn Maiden wielding her bone needle. Twelve in all: the spokes of the Spinning Wheel.

I had to crane my neck all the way back to get a view of the glass dome high above us. The sun was setting and through it, I could see the sky turning a lush, deep blue. If I squinted, I could just make out a twelve-pointed star at the dome’s center.

“So much glass,” I whispered, my head reeling.

“But no frost,” Mal noted.

“Heated pipes,” David said. “They’re in the floor. Probably embedded in the columns too.”

It was hotter in this room. Still cold enough that I wouldn’t want to part with my coat or my hat, but my feet were warm through my boots.

“There are boilers beneath us,” Nikolai said. “The whole place runs on melted snow and steam heat. The problem is fuel, but I’ve been stockpiling coal.”

“For how long?”

“Two years. We started repairs when I had the lower caverns turned into hangars. It’s not an ideal vacation spot, but sometimes you just want to get away.”

I was impressed, but also unnerved. Being around Nikolai was always like this, watching him shift and change, revealing secrets as he went. He reminded me of the wooden nesting dolls I’d played with as a child. Except instead of getting smaller, he just kept getting grander and more mysterious. Tomorrow, he’d probably tell me he’d built a pleasure palace on the moon. Tough to get to, but quite a view.

“Have a look around,” Nikolai said to us. “Get a feel for the place. Nevsky’s unloading cargo in the hangar, and I need to take care of repairs to the hull.” I remembered Nevsky. He’d been a soldier in Nikolai’s old regiment, the Twenty-Second, and not particularly fond of Grisha.

“I’d like to see Baghra,” I said.

“You’re sure about that?”

“Not remotely.”

“I’ll take you to her. Good practice should I ever need to walk someone to the gallows. And after you’ve had your fill of punishment, you and Oretsev can join me for dinner.”
