The next hour was spent exploring the various cubicles to the sides of the main hall. Some were huge, scaling many stories, and revealed evidence of previous activities and testing; others were now storerooms or small workshops; whilst others were completely stripped, black and empty, echoing to the coos of pigeons and their stink. Some parts of this building had been derelict, or unused, for a while. In one of the larger test cells, which was called Cathedral (so I was now lost for a name for the building as a whole), I took a ladder into a dark, dank loft chamber. As the door closed behind me, I could hear the hundreds of "coos" and scuttling of nervous birds in the darkness. Moving in any further would’ve caused a feathered maelstrom, resembling a scene from Hitchcook’s The Birds. It really wasn’t worth the bother (or mess, or eventual infections).
