Baaj

Baaj is a mass of ruins off the mainland of Spira, located south of the Island of Bikanel in Final Fantasy X.

Baaj Island
The area once known as Baaj is where Tidus appears following the attack on Zanarkand by Sin. Long ago the island housed a great city which fell victim to Sin. The island sank and all that is left is interconnected ruins surrounding the Temple.

When Tidus arrives and begins exploring the ruins, he is attacked by Geosgaeno and barely escapes with his life, winding up stuck in a ruined chamber of the temple. This same chamber is viewed in a flashback from Seymour's past. Tidus later is rescued by the Al Bhed.

Upon the party's (optional) return, they fight Geosgaeno and defeat it. They can now enter the Chamber of the Fayth, where the Aeon Anima, summoned by the Fayth of Seymour's mother, rests.

Baaj Temple
Baaj Temple was a former temple of Yevon, all that is left of the once great palace is a mass of ruins. The entrances to the temple are all underwater and various fiends swim in the waters, threatening any visitors.

It is here where Seymour Guado and his mother, a human woman, were sent by Lord Jyscal Guado after the Guado rebelled when they learned their leader married a human woman and bore a child with her. Seymour lived in Baaj Temple during nearly his entire childhood due to the outside world seeing him as an abomination for being half human, half guado. Years later, after rejoining the Guado, the Fayth of Anima, Seymour's mother, was moved into Baaj Temple by Seymour, now a priest of Macalania Temple. He often revisited the Fayth of his mother, while deciding whether or not to carry out his plan of becoming the new Sin and destroying all of Spira. Shortly after Seymour left Baaj for the last time, the temple was attacked by Sin and reduced to the ruins that exist in FFX.

Baaj is not accessible in Final Fantasy X-2.

Temple Aeon
''Since Baaj was a "lost" Temple of Yevon, the original Fayth cannot be Anima as it was only placed there a few years before Yuna's pilgrimage began. It is possible that Yojimbo was the original fayth of Baaj. Although there is no information which supports this theory, the absence of the Fayth after it was stolen could have been the reason why Baaj was abandoned and "lost".''
