"Timeline
The timeline of Final Fantasy XII as compared to Final Fantasy Tactics.The timeline of Ivalice as presented in the games was left quite vague, and formerly other official sources had said little on the matter. A few sources have made their own conclusion on the timeline of Ivalice.[18][19] The official timeline, however, was eventually given in the Final Fantasy XII Ultimania Omega, and placed the events of Final Fantasy XII before those of Final Fantasy Tactics.
There is no direct mention of Ivalice in Vagrant Story. However, several references are made; the Kingdom of Valendia, the setting for Vagrant Story, shares its name with a continent of Ivalice appearing in Final Fantasy XII. The Kiltia religion, featured in Final Fantasy XII, was the religion of the ghost town Leá Monde, in which the story takes place. Additionally, a quotation from Alazlam J. Durai, a famous historian of Ivalice who lived 400 years after the Lion War (and narrator of the Zodiac Brave Story told in Final Fantasy Tactics), is used at the beginning of the game,[20] and the descriptions of several items make direct reference to the same story.[21] This would seem to place Vagrant Story latest in the timeline, given its direct references to the events of Final Fantasy Tactics.
Some confusion still persists, particularly due to the facts surrounding Saint Ajora, who was executed 1200 years prior to the events of Final Fantasy Tactics,[22] yet in the Clan Primer of Final Fantasy XII is said to have separated from the Light of Kiltia religion shortly after its foundation, already two thousand years old.[23] While no gender is specified in the North American release of Final Fantasy XII, in both the Japanese Clan Primer and the Ultimania timeline, Ajora is referred to as 聖女アジョラ, Holy Woman Ajora, while Ajora of Final Fantasy Tactics is male.[22][24][25]
The appearance of some special characters in Final Fantasy Tactics may have further added to the confusion of the era the game takes place in."
