That was close. Soft bluelight glowed all around the water-filtering machinery. Hour eighteen: I knew by the rush of water. The upper workers adhered to a strict schedule.

I checked my tool belt to make sure nothing was broken and my flashlight still worked. Then I climbed from the ductwork and made my way to level two by taking a shortcut through an air conduit. Traveling through the pipes and air shafts, I avoided seeing my fellow scrubs. But my peace and quiet ended too soon as I opened the vent, swung down and landed in the middle of a crowded corridor, scattering scrubs.

Someone knocked into me. “Watch it!”

“Come to mingle with the lowly scrubs, your highness?” A mocking bow.

Used to curses and hostile glares, I shrugged. The mass of people in the tight corridor jostled and pushed me along. Life in the lower two levels teamed with scrubs at all hours of the week. They moved from work to their barracks and back to work. We were called scrubs because rust and dust were the twin evils of Inside and must be kept at bay; however, scrubs also maintained the network of mechanical systems which kept both uppers and lowers alive.

The scrubs shoved. They frowned. They complained. I hated every one of them. Except Cog. No one hated Cog. He listened. Empathized with tales of misery. Made people smile. A rare occurrence—as rare as a person like Cogon.

I headed toward the cafeteria in Sector G2. It stayed open around the clock. As far as I could tell, Inside’s length and width equaled a square with four levels. All constructed with sheet metal. Overall measurements, by my calculations—for reasons unknown Inside’s exact dimensions and specifications were classified—were two thousand meters wide by two thousand meters long by twenty-five meters high. Each level was divided into nine areas.

If I drew a square with two lines across and two lines down inside it, I would end up with nine smaller squares. The first row’s three squares would be labeled A, B and C, the next row D, E and F, and the last row G, H and I. With this configuration, there were four Quadrants A, C, G and I, which were Inside’s corners, and five Sectors B, D, E, F and H. That was the basic map of each level. Boring, unoriginal, and predictable to say the least.

The cafeteria and dining room for the lower two levels encompassed all of Sector G2. The number two meant it was on the second level. Even a four-hundred-week-old scrub couldn’t get lost. Hydroponics resided directly below in Sector G1—the lowest level—making it easy for the food growers to send vegetables to the kitchen scrubs.

The hot, musty smell of people packed together greeted me at the cafeteria’s door as the noise of them slammed into me. I paused, deciding if eating was worth being in the same room with so many scrubs. My stomach growled, overruling my reluctance.
