Ok, we're kicking off!
Dallas and Marduk will take their main areas; Dallas in the largest Museum room, and Marduk at area A, watching the Museum itself.
Ten minutes from time. Visitors to the Museum have thinned, but there are still several around.
A large gaggle of schoolchildren is the main group remaining, amongst the other casual visitors. They seem to have made a loop of the museum, and at this point are moving from the main corridor into the largest room, whereupon afterwards you assume they will exit.
Traffic is thinning outside as well, as the light fades also. People walking all round point A. light traffic at C and E, bugger all at B and D.
