BJ while the fortress starts to fall (r18)

Bit by bit, more and more of the ruble lost its balance and fell down the side of the pile, making for a great measuring tool of the progress of the engineering corps working to remove it from the other side. 

Located more in line with the ongoing work, both Leo and Mei could hear some distant noises mixing in with the constant commotion of the people fighting relatively nearby, a privilege that the guards atop the walls were deprived of merely due to… how high those walls were. 

The very thing that was supposed to give them an advantage over anyone who would even think about attacking the fortress now rendered them not only deaf to the slight sounds of the ongoing work but also made them unable to see it, be it due to some sort of illusion spell hiding the engineers or… Or simply the way the wall was constructed.
