“A hole.”

Raiding a maintenance closet, we found the needed items and climbed through the air shaft. A huge section had been cut open, revealing the Gap above. Hank and his team muttered in amazement and wanted to ask questions, but the urge to hurry pulsed through my veins. The scrubs might have filters, but they wouldn’t last without fresh air.

I raced through the Gap. Cogon kept pace despite his size. We stopped at the uncovered west Wall. I shone my flashlight over the exposed metal, counting to twenty.

Rows and columns of twenty rivets. Starting from the corner and moving right.

Twenty. Twenty. Twenty. Twenty. Twenty. No deviations.

Twenty. Twenty. Twenty. No creativity.

Twenty. Twenty-two. I found the blind. A sheet of metal covering Gateway. I pointed and Cog pulled a chisel from his tool belt and removed twenty-two rivets from each side. The metal blind had been connected to the wall for so long, it remained in place despite the removal of the rivets. Inserting the edge of a crowbar Cog pulled with all his strength. Then moved to another spot.

The metal groaned and squealed and finally dropped down. A loud clang echoed throughout the Gap. We didn’t care who heard it.

Behind the sheet was Gateway.

Wild joy shone on Cog’s face. An ecstatic sizzle pumped through my veins. Gateway even appeared different than a regular door with its rounded corners and a black substance shoved into the crack between the door and the wall. The bulging substance ringed the entire door and was smooth and hard. When I tapped it with my fingernail, it didn’t clang like metal but produced a solid thumping sound.

Cut from one piece of metal, the door also lacked a knob or latch. But a small computer screen had been installed next to it. I pressed my ear to Gateway. Nothing to hear, but the Hum. The icy surface sucked warmth from the side of my head.

I pulled away. Now I knew why Inside was always heated. Outside was cold.

“Do you know how to open it?” Cog asked with a reverent tone in his voice.

“I have a code. But the uppers will be alerted.”

“Trell, there’s been a rebellion in the lower levels. I think the uppers are probably a little busy helping the Pop Cops to restore order. Besides, I doubt we’ll get another chance.”

Good point. Steeling myself, I touched the screen. It grumbled and grunted as if I had woken it from a deep sleep, then it glowed. Squares with numbers shone from the display.

With my heart slamming, I typed in the number code and hit the enter button. For a moment, nothing happened.

Then a horrible sucking noise sounded and Gateway’s door sunk in first before swinging to the side with a loud squeal of protest. Weak light emanated as a puff of stale air blew in our faces. We coughed.

Nothing jumped out. Water did not flood Inside. No unknown substance oozed through. No strange beings flew through. No voices called or cheered in welcome.
