This is a new area, called the Berry Patch. It's directly north of Ferreus Town, and it's where the Berry Master now lives. I made it, partially because I wanted to do some mapping, but also because I felt chapter 4 was too short, so now you'll have to gather berries for the Berry Master so she can make medicine.... OR you can pay her $2000 and she'll give you a bottle she prepared earlier. Your choice :)

I haven't really decided which Pokémon you'll find here, but it'll likely be berry themed.
