Most of the group notices a strange sort of tingle in their teeth that grows as they get closer and closer to the intersection. Eir, Glimmer, and Bubble Boy (the last one indirectly, of course) notice thin lines of a strange stone which would be the source of the feeling. It's a bit white, but also hard to look at for the more normally eyed of the group.<br/><br/>Glimmer's studies remind her that it's sometimes used by non-animistic mages and theurgists for banishing purposes, but not much else.<br/><br/>But more noticeably, there's an echoing thud where some spell hit a far wall and made noise. Everyone notices that if only because of the relative quiet; a noisier local might have covered it up.
