As hope begins to dwindle, speak with everyone while at the campsite. Go southward after Kimahri, then left at the Spring. You’ll meet with Yuna as some "Suteki Da Ne" plays in the background. After that rather … expressive cutscene, go back to the previous area, grab the Lucid Ring , then head to the crossroads. Go west two areas for a Jecht Sphere . Go far to the east to find the lands of tranquility. Or something.
