* Safety in Muggles: There's actually a spell that more-or-less lets you do this; you can blend into a crowd and it renders you invisible (and immune to magical sight or tracking), as long as you have enough people around you.
* Seers: There's a whole divinatory system related to the City. One SC is known to be particularly good at it. Another character has a retrocognition spell, allowing them to see what happened in the past at their current location. 4/5
