Another dancer arrived in the city that day. He didn’t contact the first one. There was no need. Each of them knew what preparations were needful, and set about making them. The dance would call to them when it was time, as it had called them there in the first place.
Eluding authority figures was getting more difficult in the city. There were more of them each day, and not a few of them were heavily equipped with armaments and lightly equipped with self-control. That would make things harder, at least until the dance began in earnest. After that, it wouldn’t matter anymore.
