You will meet up with Tromell Guado at the entrance who will ask you to go into Maester Seymour’s manor. Before you leave though you will get a quick explanation of how to customize equipment. The basics of equipment customization is that you can use items to fill in any empty abilities on weapons or armor that you have.
The first door in front of you leads to the Guadosalam Inn. You can rest and save your game at the Save Sphere here. To the right of the entrance to Seymour’s Manor is a treasure chest that contains a Mega-Potion. Enter the doorway to the house on the far left side of Guadosalam to find an Al Bhed Primer Vol. XIII laying on the ground as well as a treasure chest at the back of the room that contains 3,000 gil.
You can now go inside Seymour’s Mansion which is the large red door at the back of Guadosalam (next to the treasure chest with the Mega-Potion that you picked up). On the second floor you will find a treasure chest that contains two Hi-Potions.
You now have to talk to all of the people in this room to continue the story. Try to enter the door on the bottom floor to continue. Speak with all of your team members again in the Great Hall.
Take Tidus, once you are back in control of him, and go just outside of Maester Seymour’s mansion to meet up with the team again. The entrance to the Farplane can be found on the top-most level of Guadosalam. Follow the pathway along to meet up with your team again.
Talk to Lulu and Wakka and then walk over to Yuna to continue the story along.
The “Brotherhood” weapon that Wakka had previously given to Tidus now contains a few additional abilities including Strength +10%, Waterstrike and Sensor. It is now a fantastic weapon - equip Tidus with it before you continue. There is also a hidden chest on the pathway to the Farplane that contains eight Lightning Marbles. Use the mini-map on the screenshot below to help you locate it.
You can use the Lightning Marbles to add “Lightningproof” to some of your equipment which will come in really handy for the next portion of the game (the Thunder Plains). Go back to Maester Seymour’s Mansion to continue the story.
Side Note: O’aka XXIII can be found in the item shop. His items are much cheaper if you donated money to him earlier in the game. Fill up some on any items you may be missing before you leave Guadosalam. You may also wish to purchase some of his ‘Yellow’ gear which has the ‘Lightning Ward’ ability as this equipment will be very useful in the next portion of the game.
Talk to each of your party members while Yuna is meeting with Maester Seymour. Talk to Lulu twice and then find Rikku. Finally, talk to Lulu one last time to continue. Lulu (or sometimes Rikku) will tell Tidus not to fall in love with Yuna and there will be three options given to continue:
- Too late.
- You're more my type, Lulu.
This does impact cutscenes that occur later on. The character with the highest affection value will partake in certain scenes later on in the game. It does not have that much of an impact though on overall gameplay so choose whichever option you would like.
Head over to the Shop to find Kimahri exiting. He will explain that the Guado Potions which are purchasable at the shop are “good”, which is definitely true. They are not actually referred to as a “Guado Potion” though when you go to buy them in the shop. Talk to Lulu one more time.
Walk down the ramp near the entry way to Guadosalam and you will run into Shelinda. Shelinda will explain that Maester Seymour already left. Go back up and meet up with the group outside of the Mansion.
Now that Maester Seymour has left Guadosalam you can pick up the Venus Sigil for Lulu's Celestial Weapon, the Onion Knight. Travel back into the Farplanes and you will find a treasure chest on the left side of the screen. Open it to receive the Venus Crest.
After Yuna has rejoined the party you can head down the walkway towards the Thunder Plains.
