The Dwarves of the Bodensee
Each in their own way, they spend a day in Tasgaetum. Many of the Dwarves seem puzzled, at least during working hours, as they wonder about just what it is the odd visitors are doing.
Eventually it becomes apparent: Aha, this is a trade, they are working on something, and this is how they practice.
Even that seems a little odd to them, after all, the troupe is all (apparently) professional and experienced at their craft, and you don't see experienced Dwarven craftsmen knocking out practice pieces.
Or maybe you do... the characters overhear Dwarves debating this.
"True, True, not like an apprentice would, but when my cousin Obirin invented sour cherry bread he did practice loaves for a while before he'd sell one, and he's no novice baker!"
The entertainers become the subject of many a conversation in the little town. It's how it often is- in such a small and remote place, there often isn't much to talk about. Whenever anything novel presents itself, people are glad just to have a new subject!
And their discussions, at least when the characters overhear, reflect Dwarven culture and Dwarven ways. They focus on technical things, and on philosophy. No comments on what the performers are wearing.
As the day progresses and the characters periodically regroup, Celeste points out a minor dilemma, having been put in a philosophical mood by listening to one too many Dwarves.
"You know, we really can't observe anyone in their natural state, can we? What we see is their state in our presence, which can be different. On the other hand, it would be even more disruptive with the whole caravan here. In a way we get to see more of the normal life. I'm so used to my father putting together the show... do we know yet what we'll be doing when we get to the Dwarven city? It's a very important show, and it's... well it's just us. This is the first time I've done anything like this."
