Just a bit of routine maintenance on the gatehouse (and most of the reason why the guards weren’t the ones out waiting for Lehn).  They keep a careful eye on the gatehouse workings, since it guards the only way in or out aside from flight.  There’s a duplicate set of gears on the other side of the archway just in case one side breaks, and they examine both sets periodically.

The next few pages are going to be fairly complex as we see more of the sanctuary and the courtyard, but I have hope they won’t take too long to draw.
