As soon as you land, Professor Juniper will talk about Cheren and then about Reshiram and Zekrom attacking two years ago and stuff, then how Team Plasma wanted the Dragon Pokemon. She says that you should talk to the Gym Leader of Opelucid City, Drayden, to hear about stuff. She'll ask if you'll do this for her. Go ahead and say Yes, then Bianca will head on over to Reversal Mountain, leaving you free to explore Lentimas Town.
Before leaving the runway, head a little north and then walk through the break in the fence, follow the path, and walk up the stairs to pick up a Fire Stone, which can be used to evolve Fire-type Pokemon such as Growlithe or Pansear, or evolve your Eevee.

Some of these moves can be pretty useful, particularly Dragon Pulse if any of your Pokemon can learn it, thanks to the upcoming Gym being a Dragon-type Gym.
Shard to Find!
Need more of the different colored Shards? One way to acquire a whole ton of them is to take a bike ride in the Relic Passage. Stock up on 30-50 Super Repels (they're most cost-effective than Max Repels), use one, then ride your bike back and forth, preferably in a wide-open area of the Relic Passage. Just keep riding around until you find some swirling dust. In the Relic Passage, you'll find Red, Blue, Yellow, and Green Shards in the swirling dust, as well as Drilbur and Onix. You can usually amass a pretty decent amount of shards this way. Super Repels aren't that expensive in the big picture, plus there are so many ways to make money that you shouldn't have any problems.
Inside of the Pokemon Center, talk to the old lady and she'll give you a Spell Tag, which is a held item that powers up Ghost-type attacks by 20%.
The southwest house has a Battle Girl in there that'll give you TM57 (Charge Beam) when you talk to her. It's a weak Electric-type attack, but it has a 70% chance of raising the user's Special Attack by one stage. It's pretty handy (although would have been much more handy before the Gym), plus quite a few Pokemon can learn it.
Anyway, as you can see, there's really not all that much to do here, so head on to the east to reach the outside of Reversal Mountain!
