What this is will be revealed in upcoming pages, but I just wanted to mention that I had no idea this was there when I started on this volume ;) The idea came suddenly as I sat in Paperchase's coffeeshop during my last stay in London. Can't imagine the story without it now!
There is still some work to be done on the shading, but I'll be all tied up for a few days starting this afternoon so I wanted to get this up before I disappear. Also I may replace/add to the symbols later, as I have more interesting ones scribbled on a piece of paper back in Beirut.
