Alright, so I haven't played this save file in months and I wanted to get back into this play through but I have no idea where I am supposed to go next. I talked to the counter guy at the grand hall and he told me that my next gym leader fight is Luna in Iolia (maybe that's how you spell it) and I know
What is the next thing I'm supposed to do? I've run all over the map looking for hints and I can't find anything.
Edit: People helped out on the discord, so I'm all good
