I thank you for clearing this up effectively. You don't know how annoying point 2 is for me especially.1. Yes, Fairies. And they're not all sunshine and giggles, either. Most are pretty malicious bastards.
2. Vanilluxe and its relatives are conceptually sentient snow-capped icicles given life through the energy of the morning sun, according to Vanillite's White and BW2 Dex entries. They only look like ice cream cones. Not to mention they were created by James Turner, a Westerner.
3. Trainer customization is 100% a thing, and it's gonna be awesome.
Also Stellar for the love of all things X&Y, please update the OP with everything we know so far. It's been over a month now. It'd be tons of help for newer users, and it'd save those of us in the know a few minutes time responding to them.
To move the subject onward, considering the Eiffel tower appears to be a gym, where could the location of the battle tower/facility/train be? I'm hoping for a battle bus, but that's just me.
