Timeline

The following is a timeline for Xenosaga, which is ambiguously set sometime between 6000-7277 A.D.

Xenosaga uses an era called T.C. (Transcend Christ). For example, Shion Uzuki was born T.C. 4745, and this would still be sometime 6000-7277 A.D.

The reason for the unknown certainty is because the scene in the opening of Episode I begins in 20XX A.D., then it shifts to "4000 years later", placing Xenosaga in 6000 A.D. Supporting this, Wilhelm says Ormus was founded "approximately 6000 years ago" when Jesus died.[1]

However, the Xenogears timeline in Perfect Works claims T.C. was adopted in 2510 A.D. This also occurs in the Episode III strategy guide timeline. 2510 + 4767 would set Xenosaga in 7277 A.D.

Sources for this timeline include the games and a poster that came with the Episode III guide.

Although Xenosaga and Xenogears are said to be set in different continuities, the events within each game's continuity within the T.C. era are almost exactly identical up to a certain point. However, there are divergences, and it is technically an assumption that the same events occurred in each game, so please do not use Perfect Works as a source for the Xenosaga timeline.

Prologue

The Zohar at Lake Turkana, Kenya, Africa.

An object is unearthed in Lake Turkana, Kenya by Dr. T. Masuda and his team: the Zohar. The Zohar is also found with a written copy of Lemegeton.

The Zohar discovered by Masuda was transferred to Vector Industries' labs in Toronto, Canada, where various examinations and experiments were performed upon it.

A.D. 2XXX

Vector Industries scientist Grimoire Verum deciphers Lemegeton and creates Program Lemegeton. Using it, he performs the link experiment to the Zohar using Nephilim Verum. This is because it had been discovered that the Zohar produced tremendous energy in response to a specific brainwave wavelength and everyone had become fixated upon finding a method to extract it. As a result, a dangerous space-time anomaly is produced.

Humanity is forced to abandon Earth and colonize space. The Immigrant Fleet (Ormus) leave Earth using a spaceship called Pleromam, built by Vector Industries. The Immigrant Fleet took records of Earth with them, such as culture, important art, books, the Bible, and even to the extent of a quote from Paul McCartney. They also take the Relics of God such as the Vessels of Anima and Zarathustra, which were created by Mary Magdalene and Yeshua/chaos.

In order to prevent the spreading of this disappearance phenomenon to the entire universe, Wilhelm sealed away Earth. The sealed Earth was thought by everyone to have disappeared (although, in actuality, it is only reduced down to the Planck Scale).

A.D. 2510

T.C. (Transcend Christ) is adopted.

Transcend Christ Era

T.C. 0016

Earth is re-named "Lost Jerusalem". Because of Wilhelm, the way to it is no longer known.

Blank Space of 4000 Years

During this time the Galaxy Federation expands to half a million planets throughout the known universe. The Galaxy Federation is also forced to relocate its capital four times, eventually ending up on Fifth Jerusalem. Despite that humanity has colonized the universe for thousands of years, no other intelligent lifeforms (aliens or other species) have been found.
At an unknown point in time, the Immigrant Fleet settles on a planet which they name Abraxas. It becomes the site for them, Ormus, and the People of the Zohar. They keep the Relics of God on Abraxas.

T.C. 4000

At the start of the T.C. 4000s, the Immigrant Fleet reunited with another fleet that had escaped from Earth--a group that had already formed a united organization of nations in the form of the Galaxy Federation. The two groups began mutual exchanges, but their backgrounds and cultural disparities were too much to bridge. Most importantly of all, the Immigrant Fleet was in possession of the Zohar. This led to a history of wars and truces that has repeated itself countless times.

T.C. 4400

According to Pier Piper, at the turn of T.C. 4400, Vector Industries had a U.M.N. management and administration department. They were behind the first theories of virtual reality construction inside the new U.M.N. "Carnegie" was the name of the mathematician who served as the leader of the organization at the time. Because of his ideas, scientific progress jumped forward rapidly in the next two hundred years. Without his research, virtual reality would still be hundreds of years away.

T.C. 4474

An early-model Realian made by "Tyrrell" of "Lamech Model 3" is built. Its information can be found in the Proto Merkabah in Episode I.

T.C. 4500s

The Immigrant Fleet appears in the Michtam star system and claimed sovereignty over planet Abraxas, their "holy land". A protracted conflict between the two groups started in the Michtam system not long after.

T.C. 4580s

On Abraxas, Draper is a region in the suburbs of Archon, densely packed with the facilities of firms in the biomedical sector. It was once used as an agricultural area, taking advantage of its fertile soil, but the bulk of the land was seized by the Galaxy Federation in the late T.C. 4580s. At that point in time, the Immigrant Fleet had territorial rights to Abraxas in all but name; while the Federation acquiesced to this ostensible fact, it demanded the partial transfer of ownership of some of Abraxas's land to them as compensation. The Federation's semi-forced ownership transfer of the Draper region is thought to have been a part of these demands.

T.C. 4590

The Life Recycling Act is proposed.

T.C. 4591

The Life Recycling Act is passed.
In T.C. 4591, the Draper region was opened up to private use by Dmitri Yuriev after a branch of the Yuriev Institute was built there. Every private business in the biotechnology sector set up shop in the area, hoping to enjoy the new benefits provided by the Life Recycling Act in a region closely linked with Yuriev.

The territorial rights of planet Abraxas go to the Immigrant Fleet.
