"Meaning, I walk into what's supposed to be my seminar on astronomy - funnily enough - and find this place, and it looks like a bar. It has tables and chairs and an inn upstairs and serves beverages, it isn't full of things for which I can discern no purpose. So I was figuring even if it's paying visits to multiple worlds, it's probably picking similar worlds, but I guess not all worlds that have tables and chairs have equally normal things like square planets and dragons."
