The “Ann and her Sisters” side quest involves speaking Ann aboard one of the Airships that travel between the various Aerodrome locations throughout Ivalice and then seeking out each of her sisters aboard each of the other Airships.
Travel to an Aerodrome and board one of the Airships. The first trip that you should take is between Rabanastre and Bhujerba. Choose to travel “By Leisure Craft” which will allow you to explore the Airship during the journey (whereas “By Private Cabin” will just take you straight to the destination).
Take the doorway at the bottom of the staircase (directly behind the area where you first start off when aboard the Airship). Speak to the man named Rande and the woman named Ann on the bottom floor to initiate another side quest. Ann will give you an item called Ann’s Letter. Ann will ask you to seek out each of her sisters for her.
There are now seven flights that need to be taken – it does not matter which flight you took to first meet up with Ann. The flights are:
- Archades to Nalbina Fortress
- Archades to Rabanastre
- Balfonheim Port to Archades
- Balfonheim Port to Nalbina Fortress
- Bhujerba to Balfonheim Port
- Bhujerba to Rabanastre
The are a number of routes that you can go that allow you to take one continuous pathway. Two examples are indicated in the graphics below. You should either go:
- Archades > Rabanastre > Bhujerba > Balfonheim Port > Archades > Nalbina Fortress > Balfonheim Port
- Balfonheim Port > Archades > Nalbina Fortress > Balfonheim Port > Bhujerba > Rabanastre > Archades[FFXII-Location Map Ann’s Letter]
Speak to the lady behind the counter during each of the trips. Each time it will be one of Ann’s sisters.
The last sister will give you a Ring of Renewal accessory as a reward for completing the quest.
The Ann’s Letter side quest is now completed.
