Zidane will wake up in a cell with Regent Cid. Kuja will speak to the two and explain that he needs Zidane and his team to help him on a quest. Zidane will be given two choices: “I have no choice” or “Never!” - it does not matter which you select. Move forward and stand between the two Black Mages to continue the story.
Kuja will explain that he is sending Zidane and his team to a place called Oeilvert, a place located south of the Seaways Canyon on the Forgotten Continent, to retrieve a Gulug Stone. Kuja is unable to go because there is an anti-magic barrier around Oeilvert. He will then ask Zidane to select three additional party members to go with him.
As Kuja mentioned, there is an anti-Magic barrier around Oeilvert, which means that any party member that goes with Zidane will not be able to use magic-based attacks. You will have to complete a dungeon with both teams that you create though so it is important to keep them as balanced as possible:
The parties should be split as follows:
| Oeilvert | Desert Palace |
|---|---|
| Zidane | Quina |
| Dagger | Eiko |
| Freya | Vivi |
| Steiner/Amarant | Steiner/Amarant |
Kuja will summon each of the party members that Zidane selects to come join him. Run up the stairs after Kuja warps the team out of the room and over towards the Hilda Garde 1.
The airship will automatically take the team to the Forgotten Continent (the only continent that was unreachable while sailing on the Blue Narciss ship).
Touch the Hilda Garde at any time to speak to Zorn and Thorn and you can access a small shop if you need to purchase any of the regular items. There are a few things that you can do in this area if you managed to complete some parts of the Chocobo Hot & Cold side quest and if you managed to obtain the Mountain Ability for your Chocobo.
There is a Qu’s Marsh just north of where the Hilda Garde III lands and there are some Chocobo tracks just north of there. Use some 
Gysahl Greens to call forth Choco. There are two Chocographs that you can now dig up if you obtained them before heading to the Forgotten Continent:
You can also reach two more Mountain Cracks on the Forgotten Continent:
If you brought Quina with you to the Forgotten Continent (which you shouldn’t have) you can use this opportunity to go Frog Catching at Qu’s Marsh and you can also pick up the Earth Shake Blue Magic spell from an Adamantoise in the area.
Make sure to equip Freya with the 
Dragon’s Hair lance (if you found Mountain Crack #3) as this is the strongest weapon for her in the game.
You can find another Friendly Monster in the forests of the Forgotten Continent. This creature is called a Jabberwock and it asks for an 
Emerald. Give it one and it will give you a 
Moonstone and 40 AP. A great prize that will help you learn abilities extremely quickly.
That being said, you may want to save this side quest for later if your party if full of characters that you are not planning on using later on in the game. Why level up abilities on character that you don’t plan to use? You can always bring your main party back on Disc 4 if you’d like.
Finding the Jabberwock is part of the Friendly Monsters side quest. Click on the link for more information.
Oeilvert’s location is marked on the map. It is south of the Hilda Garde 1 drop off location in the center of the Forgotten Continent and shown in the screenshot below.
