When you enter some people will talk to Barret. You can buy weapons, Materia and items here although they’re not very good and you need 3000 Gil to enter the Gold Saucer which is where you’re going next. You can stay in the inn to the north. Go left to Ropeway Station. This will take you to the Gold Saucer. You will talk to your friends and learn more about Barret’s past before boarding. When you get to the Gold Saucer you’ll see a Save Point to the left but you can’t use unless you have GP. Talk to the woman at the IN sign and pay 3000 Gil to enter. You’ll talk to your team for a while. Talk to one person who you want in your team, you can only have one at this point. Go to the Wonder Square and you’ll meet Cait Sith. watch him tell your fortune which goes completely wrong apart from the ladt reading. He’ll then join your team. He has two Materia, Manipulate and Transform. Now go to the Battle Square and find the guard’s been killed.
You’ll talk to the woman behind the desk and some guards and Dio will show up and accuse you of killing everyone. You’ll run inside the Battle Square and will be ambushed by some robots. Don’t worry, you won’t have to fight them. You’ll be caught then chucked through the ‘Gateway to Heaven’ which lands you straight in jail. You’ll find Barret and talk to him for a bit. Go through the gate.
