I'm trying to get the gillionaire, so I have to capture Vorban in Omega Ruin, right? The problem is I have no idea about this vorban. I even cannot find its name in my monster list which I got from a website. Is there somebody has any information about it? or the other easier way to get Gillionaire? Detail, please...

Oh, yeah one more question, if I had come in to inside the body of Sin, Can I come back to the airship before fighting Yu yevon?
