Before going to the next area it's a good idea to go back to Sword Valley and Galahad Fortress to make sure you've killed all the unique monsters in them to get their affinity coins, because those areas won't be accessible for the rest of the game. The gold chests they drop have a chance of having a level 10 art book in them (from now on all gold chests will). There's a save trick if you're interested, save before opening the chest and if you didn't get a book, reload and open it again (be careful because the unique enemy may respawn).
There's also the quest to get Monado Armour, it's the second quest Eleqa gives to you. They have a requirement of 1.25 stars, so you have to do 1-2 quests in Fallen Arm before they are available.
Now that you have Fiora in your party you can gem craft like a pro. Just make sure to never raise her affinity with Riki and max the affinity between Shulk and Reyn (it should be a heart). I'll explain this later.
