When you first enter the World of Ruin you start off with only Celes. Then you get Sabin, Edgar, then Setzer and the second Air Machine. Then you are on your own for getting everyone else. Below is a list of the order that I get the people. I found that it has always worked quite well for me, so I thought that I would pass down the information. If you have a different way of doing it the please E-mail me.
If you find any mistakes or if I left someone out please E-mail me so that I may fix it.
