Pokémon X and Pokémon Y

I'm starting to believe that the trainers in this game are quite rich. They seem more well-dressed than previous previous trainers, and they look more "noble"

The original trailer shows the town with black roofed-buildings to be just after Route 3. Meaning that just south of the town with black-roofed buildings is the starting town.
The only thing there is a huge-mansion like building, with a large stone bridge like this one:



So I believe the starting area is that huge mansion. Which is really interesting compared to the rather "average" origins of the previous trainers.

Oh, also:



too much stuff revealed at once. Fangasm overload.

Can you explain the meaning behind the picture of the ring thing for me?
