Riley kept my hand as he turned left at the intersection and increased his pace. He made another left into a smaller corridor without doors and which ended. He headed straight for the end.

I scanned the ceiling, looking for air vents. “Riley, where are we going?”

“Trust me.”

Almost running now, I kept close to him. When we reached the end, he let go of my hand and stepped to the side, disappearing.

“Hey,” I called and he poked his head out.

“Optical illusion. Pretty cool, isn’t it?”

I felt around. The wall on the left side of the end was solid. The right side appeared to have a solid wall, but the wall was actually a meter past where it should have connected to the end. The corridor jigged to the right for a meter before going straight again, but it looked like another end. After I made the turn, I glanced back. The illusion worked from both sides.

However this hallway was only about two meters long and contained one door. Riley typed in a number sequence on the lock and the door opened into our storeroom. Relief coursed through me when we entered and I plopped on the couch. I couldn’t believe I had just strolled through the upper level.

“That’s why no one knows this room is here,” he said.

It made sense. Unless you put your hands on the walls, you wouldn’t discover the illusion. “How did you find it?”

“Lightbulb duty.” When I didn’t say anything, he continued, “During training, the newbies get assigned lightbulb duty. We go around changing lightbulbs in the corridors and public areas. Then we fix the broken filaments. A painstaking process.” He waved his hand as if pushing away the memory. “Anyway, I was assigned this sector and the bulb at the end must have just burned out. It was still hot and I dropped it. The bulb landed on the rug and then rolled through the wall.”

He grinned. “It’s amazing, but that bulb has never burned out since I found this place.” Riley pulled a drawer open. It was filled with lightbulbs.

After stashing the upper’s training uniform under the couch with Zippy, I found Logan in the air shaft not far from Riley’s room. We returned to the lower levels and he raced to make his shift on time. The poor guy would be awake for thirty hours straight. Not fun, but doable. Having worked my shift, Anne-Jade would also be dragging. Perhaps the news of Gateway’s existence would wake her up.

Gateway. I still couldn’t wrap my mind around all the implications. But I did know actions and alliances needed to be made and I couldn’t do it on my own. So I climbed into the heating vents to visit Domotor.

He sat in front of the computer, but turned an expectant expression toward me. I kept my face neutral, but couldn’t maintain it for long.

“You found it!”

I smiled. “We know the location.”
