In The LCA
The Constables pass through the door and into a round workroom. There are workbenches with tools and any number of projects in progress cluttering the space on the benches. The central area of the room is devoted to a large pentagram inlaid directly into the floor. Just outside the edge of the pentagram, a magic circle has been similarly inlaid. On the other side of the Pentagram and Magic Circle stands and older, bearded wizard at a wooden podium, and he appears to be rehearsing a spell.
"Oh, there you are, good, very good! Now, Constables, if you will arrange yourselves in the pentagram, yes, yes, that's the way. Do be careful, but you'll want to have your weapons out and ready when we begin. It's not a friendly place to which you are going. We'll try to place you in a less-traveled spot, so hopefully there won't be any immediate danger, but we just can't be sure now, can we?"
