Cavern of the Stolen Fayth

A cavern located in a gorge to the north of the Calm Lands which hides a fayth that legend says was stolen long ago to prevent Summoners completing their pilgrimage.

Final Fantasy X
This area is an optional side-quest in Final Fantasy X. Lulu provides the most information about the cave as the first Summoner she guarded, Lady Ginnem, died here after deciding to locate the Aeon.

The secret Aeon Yojimbo is found in a hidden chamber at the bottom of the cave. After fighting Yojimbo himself when the unsent form of Lady Ginnem attacks your party, you can enter his chamber and request his services for a price.

Temple Aeon

 * Yojimbo

Temple Trials
Battling your way through tough fiends, a battle with Yojimbo and a significant ammount of gil (> 250,000) are needed to obtain the Aeon.

Final Fantasy X-2
The Cave, like the Calm Lands, has become a tourist attraction; something which the Gullwings have reservations about. It becomes accessible in Chapter 3, when Fiends begin appearing from the Chamber of the Fayth. An optional mission begins where Yuna must rescue the trapped tourists either one by one, or all together in a specific order. After the rescue mission you can enter the Chamber to fight Dark Yojimbo.
