FFXII - Walkthrough - Balfonheim
Well you're back, and in case you're confused on where to go, a nice circled red x on the Location Man indicates where you need to go... so go there, and speak to Manse Watch.
Cutscenes, and Reddas joins your party as a guest. When you're ready, go to the Aerodrome and talk to the "Private Airships" individual. With the Strahl repaired and able to enter jagd, you can travel via airship to many dungeons you've already been to - of course, many of these places have Teleport Crystals, but still. Select "The Ridorana Cataract", and you're off!
