Note that this is the third section of the strategy guide concerning the city of Bhujerba. Refer to the main page to navigate to one of the previous pages. This section of the game pertains to the visit after escaping the Dreadnought Leviathan.
The team arrives back in the Aerodrome of Bhujerba. Penelo will give Balthier his handkerchief back and Ashe and Basch will have a quick conversation in a short cutscene that takes place as soon as you land.
Vossler will convince Ashe to allow Basch to continue to protect and escort her as they make their way to Ondore.
Use the Save Crystal to save your game and then travel back to Marquis Halim Ondore – the area identified by the Red X on the map. Ashe will explain the situation to the Marquis and ask Bhujerba to assist her in stopping Vayne.
Ondore explains that Ashe will require proof of her birthright and the team will sneak out of Bhujerba in order to travel to the Tomb of King Raithwall.
The team will land in the Westersand and you can take them straight to the Ogir-Yensa Sandsea, but this interlude affords you some time to stock up on some new items that have become available and complete a few of the optional side quests (or steps of them) which are accessible.
The items mentioned below are optional and you can skip to the next page of the strategy guide if you would prefer not to complete them.
You could start off by speaking to Lohen and picking up some new Magick, Technicks, Weapons and Armor that have become available (listed below):
You may want to purchase some of the 
Forgotten Grimoires if you have any leftover gil.
You can also complete the next part of the Ktjn side quest. Note that you do need to complete each section of this quest in order to get the reward at the end of the quest as you lose the ability to answer Ktjn’s questions later on in the game.
Travel back to the Muthru Bazaar in Rabanastre and speak to Ktjn on the stairs. She will end her brief monologue by saying “I knew my choice would bring hardship, yet…” and you will be given two answers:
Choose the first answer, “You should’ve thought it through”, as it will give you the most points.
Make your way back to the Sandsea and read the Notice Board to pick up the bill for the next Hunt.
The petitioner for Bill No. 7 for the Wyvern Lord is an Imperial Soldier named Sherral who can be found in Amal’s Weaponry shop on the upper floor.
The Wyvern Lord can be found as you make your way through the Nam-Yensa Sandsea which will be coming up shortly (Hunt 08: A Scream from the Sky).
The last thing you can do is the Sunstone side quest:
Finally, you may want to take this time to obtain a 
Diamond Armlet once you return to the Dalmasca Westersand. Check out the “How to obtain a Diamond Armlet” section for more information.
It is now time to travel into the Ogir-Yensa Sandsea on the way to the Tomb of King Raithwall as instructed by Ashe. Make your way back to the Western Divide on the west side of the Dalmasca Westersand.
