It depends. I have experienced an even split, but my experience isn't as vast as Brie's. On some worlds everything is fine -- they expect travelers and are aware of other universes.

On other world's, travelers and magic are completely foreign. I'm sure that other world's have different experiences and are a combination of the two. In general, I suggest expecting the unexpected, since I can't predict where we're going whatsoever.

[Despite her composure, this seems a bit exasperating to Genette.] The more you know about your magic, however, the more likely you are to be grounded in whatever world we happen to show up in.
