Once all three of them were inside, the double doors closed behind them. Archer didn't even try to go back and check them, they were most likely locked. Left with no other option, the team moved forward.

After a few moments Archer's eyes adjusted, and he could see the path, with the aid of the candles, barely providing illuminating the hall. There were still plenty of shadowy areas, so Archer covered them with his flashlight, slowly and cautiously scanning the areas where enemies might be.

Along the wall, he noticed a series of macabre tapestries. Although they looked ancient, Archer recognized some of the scenes from relatively modern wars. The oldest scenery depicted was maybe the Ardennes Offensive, a major German offensive move, near the end of World War II.

"The Battle of the Bulge, a World War II scene," he revealed, more to himself than the others. "Hitler's last major offensive before the war's end. They actually succeeded but due to lack of resources they had to retreat."

Since he'd been to war himself, Archer wasn't particularly disturbed by the massive body count due to foolish human ideals.

Shaking his head, Archer spoke, "Moving on."

They didn't have time to waste, but Archer walked slowly, weary of the possible, unseen dangers in the shadows.

It was doubtful the loud banging had gone unnoticed, but Gin was determined to make some small amount of progress before they were inevitably halted by some creature or another.  It wouldn't be much further until they reached their destination, and while he wasn't much for luck, perhaps it would hold for a little bit longer.  He paused a moment for Rangiku, searching the dark hallway up ahead for any possible threats.  The shinigami kept one hand on his flashlight and the other on the handle of his knife. 

"Y'alright darlin'?  Ain' much further now," he called back, keeping his voice just above a whisper; wasn't much point it being too quiet now that they'd gone and done all that banging.

As the door rumbled open, Mark's first thought was that it was awfully... loud. The noise didn't lower as the door opened further, either. Instead, it seemed to be getting worse. As the door finally gave way and they got a glimpse of their new barrier, Mark had to pause for a moment and simply gawk in silence.

"All right. This is ridiculous." Mark announced out loud, as he watched the boulders merrily make their way across the hallway, blocking their path. He wasn't sure if the others would even hear him over the noise of those things. Where the hell were they coming from?!

Some kind of conveyor belt behind the scenes to cycle the boulders around, make it more efficient...? Not that figuring it out would help much. Timing. If they could just get the timing right, it'd be fine, practically like playing a kid's jumping game.

He couldn't discern any reliable patterns.
