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.

Before Christ EraEdit


  • The big bang occurs, creating the universe.
  • Wilhelm becomes the guardian of the universe's Lower Domain.

7-2 B.C.Edit

Anno Domini EraEdit

Jesus's life Edit

  • Ormus is claimed to have existed before Jesus's crucifixion by Sergius XVII (whether or not this is a lie is unknown).
  • Jesus gives Yeshua, his miracle worker and the human incarnation of Anima, a spoken copy of Lemegeton.

A.D. 30-33Edit


The Apostles listen to the Messiah's words.

  • Jesus is crucified, creating the religion Christianity.
  • The Maiden of Mary Magdalene dies.
  • Yeshua leaves Mary Magdalene. Yeshua changes his name to "chaos".
  • Mary Magdalene, the human incarnation of Animus, dies while splitting Yeshua's (chaos') power of Anima in half to create the 12 Vessels of Anima.
  • The Apostles store Mary Magdalene's body and the Vessels of Anima in Rennes-le-Château.

A.D. 33-2000Edit

  • Due to the lack of Internet, it takes hundreds and a couple thousand years for Christianity to become spread throughout the planet, especially by those who believe in the tales of the Bible. Christianity becomes popular in Europe and the Americas. Many churches are created in Jesus' name, such as the Roman Catholic church. Many people come to believe that Jesus was the "son of God" and possessed supernatural powers such as healing, walking on water, turning water into wine, etc. However, in the Xenosaga continuity, Jesus did not possess supernatural powers, and both Yeshua (chaos) and Mary Magdalene performed miracles for Jesus.
  • Unfortunately, the spread of Christianity has many poor side effects, such as the Crusades, Westboro Baptist Church, etc. Apostasy becomes punishable by death in certain areas. Wilhelm and Yeshua (chaos) observe such horrors against atheists and non-Christians.

A.D. 20XXEdit



The Zohar at Lake Turkana, Kenya, Africa.

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

A.D. 2XXX Edit


Nephilim and the Zohar.

  • 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 Pleroma, 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.
    • Wilhelm was able to obtain the Vessels of Anima from Rennes-le-Château, but due to unknown reasons, he is unable to retrieve Mary Magdalene's body.
  • 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. 2510Edit

  • T.C. (Transcend Christ) is adopted.

Transcend Christ EraEdit

T.C. 0016Edit

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

Blank Space of 4000 YearsEdit

  • At an unknown point in time, after a long and arduous journey of wandering, 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. They also colonize an asteroid, naming it "Pleroma" after their immigrant ship, and use it as a site of worship for their Ormus religion.
    • Abraxas was used as a base of settlement by groups (believed to be under the influence of Ormus forces) that had managed to escape the Earth upon its destruction. The groups formed an independent nation unaffiliated with Galaxy Federation law, and thus declared the establishment of the Immigrant Fleet nation. However, it was later incorporated into the Federation.
  • Over thousands of years, 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.

T.C. 4000Edit

  • 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. 4400Edit

  • 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. 4474Edit

  • 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. 4500sEdit

  • 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. 4580sEdit

  • 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. 4590Edit

T.C. 4591Edit

  • 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.
