I yanked on the safety line and guessed I had another couple meters before I was literally at the end of my rope.

When I felt strong enough, I continued and discovered why meter seventy-five was mentioned in the computer. A bottom rung of a ladder started at that point. I grabbed the wide cold bar, hoping the rung would hold my weight. The smooth and rounded shape fit nicely in my hands. And my light illuminated the ladder which continued up with more rungs disappearing into the darkness.

I climbed on the ladder another meter, confirming the metal hadn’t rusted or deteriorated with time. Squinting, I shone my light higher, but the ceiling still remained out of sight. However, I thought I spotted a dim gleam of a reflection. Wishful thinking or my imagination, it didn’t matter. It was enough to justify my decision to unhook my harness from the safety line.

Despite the cold, sweat soaked the fabric of my uniform. I rubbed my moist palm on my arm before grasping the next rung. Continuing up the ladder with slow and careful movements, I tested each before allowing it to bear my weight. In the silence of the Expanse, my breath sounded loud and mechanical. My heart thudded with urgency as it reminded me of the danger. One slip, and…I wouldn’t think about it.

Instead, I focused on keeping a tight grip and my balance on the rungs. Concentrating so hard on my hands and feet, I bumped my head on the ceiling. I clung to the ladder in surprise, and when my muscles stopped trembling, I scanned the flat expanse of metal over my head. Finally!

I checked the altimeter. Inside was eighty meters high, which meant we could build six more levels for a total of sixteen. Wow. That was mind-numbing. I hoped our systems could service all those levels. And what about keeping them clean and in good condition? And when did I turn into such a worrier?

Eventually, someone would need to explore the entire ceiling. Logan had read about another Outer Space Gateway in the computer files. By the way he described the file system, it had sounded as jumbled as the infirmary’s supplies after the explosion. Between the Travas’ attempts to erase files and the sheer amount of information, Logan had said—with his usual glee over a technical challenge—that it was an utter mess.

With one last look upwards, I steeled myself for the descent and stopped. Moving the beam of light slowly, I searched for the almost invisible indentation I thought I spotted from the corner of my eye. I swept the beam back and forth over a square meter-sized section. When I was just about to give up, the light skipped over a line.

I found a near-invisible hatch! Pleased over my discovery, it took me a few seconds to understand the full ramifications of my find. Above each of the four levels we have been living in, was a near-invisible hatch to the Gap between levels. This meter and a half space housed pipes and wires and room for someone like me to move between levels without being seen.

I had thought I reached the ceiling. But the presence of a near-invisible hatch meant there was something on the other side.

SOMETHING ON THE OTHER SIDE. I REPEATED IT IN MY mind in order for the logical side of my brain to catch up. No black rubber ringed the hatch, which meant it wasn’t a Gateway to Outer Space. There could be another Expanse and room for additional levels. I laughed, but it sounded strained and metallic as it echoed. I had thought sixteen levels incomprehensible.

Only one way to know for sure, I hooked my legs through the rungs on the ladder to anchor my body. Stretching my hands up, I felt for the release.

The pop-click reverberated through the bones in my arms. I pushed the hatch. The metal groaned and creaked, setting my teeth on edge. A dusty stale smell drifted down.

When the opening was big enough for me to fit through, I shined my light inside. The ladder continued another meter before stopping. Odd shapes decorated the wall. Taking a risk, I climbed into the space. The floor seemed solid so I stepped down, but still held on to the ladder just in case.

The good news—the floor didn’t disintegrate under me.

The bad—a strange tingle zipped through my foot and daylights turned on.

Blinded by the bright white light, I squeezed my eyes shut. Even through my eyelids, the harsh brilliance stabbed like a horrible migraine.

It felt like hours before my vision adjusted.

When I could finally see, I saw a giant monster.

I screamed and hopped onto the ladder before logic took control. The huge thing was a thing, not a living breathing creature. It didn’t move. No sounds emanated. No lights shone from it. It appeared to be made of an odd black metal without rivets.

Unable to stifle my curiosity, I stepped closer. About nine meters tall and a hundred meters wide, it was too long for me to guess with any accuracy. A colossal sheep without a neck had been my initial impression. Or a long sock filled with round balls. Or glass balls all stuck together in a rectangular shape.

Either way, the whole oddity rested on eight thick metal legs with massive wheels. The head—for lack of a better word—had two large glass panes for its eyes, which reflected the daylights set into the ceiling. If the roof above this strange level was indeed the ceiling for Inside. At this point, I wouldn’t be surprised to find yet another level and perhaps a whole other society living above us.

I ringed the structure and spotted its tiny twin right next to it. Not as scary as its super-sized brother, the smaller…what to call it? A lamb? A bubble thing? It appeared to be a conveyance of some type.

Once the shock of my discovery wore off, I realized that the room I stood in was indeed a room. Inside was approximately two thousand meters wide, by two thousand meters long. This area was a fraction of that size. In fact, my body’s internal sense of measurement suspected the room’s dimensions equaled one Sector or Quadrant—six hundred and sixty-six point seven square meters. One ninth of a level. Or to convert it into Inside’s designation system so it matched the levels below, this area would be Quad G17.
