FFIII (for the DS) Help! - SPOILER ALERT -

OK. I've been playing Final Fantasy 3 for my Nintendo DS and I've made it to the main land below, and I've used my one magical key in Goldar (I think that's his name) castle to look in one of the rooms. Problem is, I need 3 others for the other rooms since there is a lock on them. What do I do?

I've been to the sewers, chatted to everyone in Amur(?), and now I'm just lost. I've been leveling up and what not to waste time, but I'd like to continue on with the story. Any suggestions? Have I screwed myself over by using the key and saving? Ugh. I don't know what to do

Uuuhm, I don't remember where but you can buy magic keys from one of the villages on the floating continent/whatever.

This site is where I usually go for gaming issues. Also, never use the fat chocobo.. there's no point putting your items there.

What's your party like? xD
