We followed him over the rocky ground, into the enclosure, past the glaring prisoners. The building itself was as stark as a military barracks, and as far as I could tell, it had served no purpose except to hold prisoners and as a hangout to discuss crazed anti-vampire schemes. It chilled me seeing it all.

A stairwell in the center of the building led downstairs to an underground level, and there, we saw Eddie, Neil, and Rose waiting at the bottom. Sydney and I followed the stairs down and found ourselves standing in a long concrete corridor that stretched off into darkness. A few doors could be seen branching off, but I had no idea what was beyond them. Beside me, Sydney winced.

“Reminds me of a primitive version of some of the re-education levels,” she murmured, shuddering.

Thinking back to when I helped rescue her, I could understand what she meant. That facility had also contained vast halls with mysterious doors, though it had had a much more clinical feel to it. It had all been sterile and lit with stark fluorescent lighting. This, meanwhile, was more like a dirty, medieval dungeon in the wilds of Utah. It made me sick to think of Jill being inside.

“We think Jill’s just down there,” said Rose. “That’s what the Alchemists’ equipment detected. I want to go in and get her, but Eddie . . .” It was clear she didn’t share his fears.

He looked a little embarrassed but held his ground. “I just can’t shake the feeling something’s off here. Why not have guards on their most valuable prisoner? And do you smell that?”

Sydney nodded, and I had to agree. “It does smell like Jackie’s house,” I remarked.

“Someone’s burned incense here,” said Sydney. “Though it’s not something you’d see Ms. Terwilliger using very much. Vetiver. Black lotus.” She frowned and scanned around. “There. There are some ashes down the hall. That’s where it was burned.”

I started to investigate, but she held me back.

“Wait,” she said. She held up her hand and spoke words in a language I didn’t know. After several seconds, glowing symbols appeared in the ceiling above where the ashes were. Sydney studied them intently until they faded away, and then she exhaled in dismay. “Damn.”

I rarely heard her swear and didn’t think that boded well.

“What is it?” I asked.

“There’s a demon here,” she replied in a tone that was far too casual for that kind of pronouncement. “It looks like Alicia summoned one to stand guard.”

“Hopper’s technically a demon,” I offered.

Her face was grim. “Not that kind, I’m afraid. This is a senicus.” Seeing our blank looks, she asked, “Have you ever heard of a hydra in Greek mythology? It’s kind of like that. Kind of. Serpentine, lots of heads. But these heads spit boiling acid.”
