You'll watch Ramsus' introduction, then you can move around Bledavik. A lady near the entrance will point you a good hotel, but don't go there yet. Visit the market and weapon/armor shops, then buy anything you need. While strolling through the the market, you'll see one of the ladies be stolen by a kid; chase the kid (into a small passage) and give him 1000G out of the goodness of your heart, then he'll promise not to steal again. Don't be a money-grubbing bastard, this kid will open up a shop for you much later (and of course it's worth it). On the same alley, challenge the other kid to a hide-and-seek game (Refer to the Secrets section for more information). Now go to the hotel and tell the owner you don't know the name of the lady to get an amazing discount of 10G. Talk to the nun and after some chit-chat you'll have to go back and look for a way to get inside Fatima Castle, so go north to visit the Shakhan Square.
You can play some mini-games and watch some funny stuff on the Shakhan Square if you want, then head north until Bart leaves your party. Visit the tournament area and sign up for it. Now go back all the way to the market and check the Eastern border where you can find a grate. A kid there will mention the hide-and-seek boy once got lost inside the well. Now go talk to the hide-and-seek boy, then go back to talk with the old man near the grate and choose the second or third option to get the Well Key. To make it clearer, just tell him you want to rescue Margie. Now go talk to the nun at the hotel and get some rest (notice this is your chance to go check one of the tents at Shakhan Square that you couldn't before and watch a small scene about a Lahan villager called Molten), then the plan will start.
Head to the Tournament area and you'll meet some familiar faces. Bart should go south of the hotel and go inside the waterway (this route is faster). Your first enemy on the tournament will be Gonzalez. Try to drag on the battle as much as you can to give Bart time. Gonzalez is slow, but has one damaging attack ("can't take it anymore!"), so heal when necessary. After you win, a menu screen will show up for you to heal Fei. Do so, then exit the menu screen and it'll be Bart's turn to move and after some playing Bart, the game automatically return to Fei's next duel (this paragraph will list all of Fei's battles, so move to the next one if you want to know what to do with Bart). Our second challenger is Big Joe (yes, the drunken Elvis-look-a-like) and he's quite weak, except for the "help" from his rabid fans. Build up a combo and make sure you equip the Metal Vest you get after the battle. Next up is Scud, and this is another easy battle to drag on, since Scud uses lots of defensive "pills". The next enemy is Dan (!) and he's quite a lot more challenging. Don't let your HP drop too much because of his "You scum" big ether attack (where did he learn that?). Also, if you refuse to fight and only defend yourself, Dan will give up and throw you Alice's Wedding Dress. The last battle is against Wiseman. Don't even bother, you can't win (or lose) this battle, so just keep wasting turns until it's over.
Bart will have to swim against the current here. Swim northeast, and again to the northeast when you reach a junction, then climb the pipe and move around the aquarium to greet some shocked costumers and get the Gold Nugget. Now go back and swim northeast, then north. On the next junction, go southeast to get a Rosesol S, then go back to the junction and go north this time. On the next intersection, take the rather long path northeast if you want a Survival Tent, or go northwest, then south on another junction to get an Aquasol S. Now go back and head north, northeast and north to reach Fatima Castle. After talking with the old man, save your game and climb the ladder. Inside the castle, Bart has to play the Solid Snake act and dodge the guards by staying outside of their sight (don't worry too much, though. If they spot you, Bart must fight, but they're quite easy). If Fei managed to entertain the crowd outside, there won't be many soldiers there and they won't respawn. You'll end up in the middle of a garden, so you should run south to a big door before the guards can reach you (get used to peek if you don't want to fight). Notice there are 3 doors at the east Corridor and 3 at the west Corridor. On the west doors you can get Hob-jerkies and a Hob-meat by jumping near the north wall in the kitchen. There's door to the southeast with a Cobra Cracka inside and the southwest room has 4 Iron Mails (there's nothing much on the middle one). Now go back to the south door and go up the stairs, then take the north door. There'll be another set of corridors with 3 doors each. Get a Rosesol S on the northwest one. Check the northeast door to hear some conversation between the guards and run to the other side to get an Aquasol S (it's difficult, but possible to escape them). Now go to the last door from any side (you'll end up in the same place) and climb the stairs. Head east, then all the way to the North (you might recognize the area). Talk to Margie and save your game. After some scenes, Bart will fight Ramsus.
Ramsus isn't really difficult, just don't attack when he is in the Mirror Stance. Fei will join the second round but Ramsus will be tougher and Miang will heal more often. Just don't attack Ramsus during the Mirror Stance again (you can use Ether, but Miang will probably heal him) and the battle should be over. After a dandy escape and some other scenes, Margie will be safe and you can bring her back to Nisan.
