Brought out of his reflections by Sammy, Heron considered for a moment, and then said, "Well, picture having someone's description, and then running all over town looking for them. Sure, a town this size isn't as bad as, say, Seattle, but it is still problematic to try and trace someone astrally unless you have an idea of where to look, or have a ritual sample to trace them with. Plus, if you just wandering about astrally, you risk getting spotted by any astral security in the area, which can complicate things, even if it isn't connected to where they're going. If we had thought about it ahead of time, I could have tasked a watcher to follow them, but that has the same problems with astral security, especially since watchers aren't generally smart enough to avoid bumping into wards if a mundane person they're following walks through one."
