This is about me

Before the creation of The World a German programmer named Harald Hoerwick fell in love with Emma Wielant, who wrote an epic poem entitled the Epitaph of Twilight. After Emma died in a car accident, Harald became distraught and created Fragment (the prototype to The World) inspired by the Epitaph. But this program was actually intended to create the ultimate AI, Aura. Harald worked on Aura as a symbol of his love for Emma as the daughter that could have been.

At the beginning of .hack//Sign Aura is asleep as her mentor program, the AI Morganna has yet to gather enough data from the players to awaken her.[2] But Morganna is intentionally trying to keep Aura asleep since she realizes that she would lose her purpose when her job—raising Aura—is completed.[1]

Morganna manages to imprison the consciousness of Tsukasa (the protagonist in .hack//Sign), trapping him inside The World, and linking his emotions to Aura's development, while she manipulates him in order to stop Aura from awakening. At the end of the series, Tsukasa is able to awaken Aura, allowing himself to log out of the game. However, Aura's awakening throws Morganna into a rage, who then sends the Phases to chase Aura down and delete her.

A few months after .hack//Sign, The World has succumbed to some severe problems, including invincible monsters and glitched graphics. All of this was a part of Morganna's intention to capture Aura and prevent her from developing Data Drain, which is necessary for her to become complete.

However, Aura is able to cultivate this power into an installation book, and attempts to give it to the legendary player Orca. Unfortunately, Skeith, one of the phases, attacks them, Data Draining Orca and causing the player in the real world to fall into a coma. His best friend, Kite, a novice player, is with him at the time, so Aura is forced to give the Installation Book to him. Upon opening the file, his player code is rewritten, and he receives the Twilight Bracelet. This allows him to use Data Drain, the only power capable of defeating the corrupted monsters as well as the Eight Phases of The Cursed Wave.

When Kite encounters the first Phase, Skeith, it is already in the process of Data Draining Aura, scattering her data throughout The World in fragments. Kite defeats Skeith, creating Cubia in return. Fortunately, Aura's consciousness is still partially functional, so she is able to send corrupted e-mail messages to him, which are possible to read but with great difficulty. With the help of other players (who later become known as the .hackers), Kite is able to face and defeat six more of the eight Phases: Innis, Magus, Fidchell, Gorre, Macha, and Tarvos. After Aura becomes complete, there is only Cubia, and the final phase, Corbenik, left to deal with. Aura tells Kite not to confront Cubia because Cubia is connected to the bracelet. However, Kite still confronts Cubia and has to destroy his bracelet to defeat it.

This makes it impossible for the final Phase, Corbenik, to be defeated, and the over twenty million people in The World could potentially die. Kite fights the final Phase anyway, but when he is about to deliver the final blow to it, Aura gets in the way and is apparently killed.

When this happens, Aura, who has collected data on positive emotions, merges with Morganna, who has data on negative emotions, completing Aura's final incarnation as the Ultimate AI. From then on, Aura becomes an omnipresent yet mostly silent force within The World, analogous to a god.

In .hack//Legend of the Twilight, Aura is able to do anything she wants in the game without fear of administrators or other people who could delete her. She holds a fake contest and posing as an administrator, bestows upon Shugo and Rena, super deformed versions of the avatars of the legendary .hackers players Kite and BlackRose. Aura gives Shugo the Twilight Bracelet, to help him fulfill his dream to become a hero, which he told her about a few months after SIGN, mistaking her for another player.

She also has a daughter named Zefie, an AI that was as powerful as she is, but with an extremely wild and uncontrollable personality, even going as far as to give players pink afros for the fun of it. Zefie was created for two reasons: One was to complete Aura by allowing her to experience child birth, and the other was to help Shugo with his goal. This event causes Balmung and Mistral to discuss Aura's evolution, in which Mistral mentions, "It's tough you know, becoming a mother that is."

At the end of the year 2014, Aura was lost. It is unknown how or why she vanished, but with her disappearance, CPU processing has increased in The World. The loss of Aura meant the networks were returning to their original specs.

The suits of CC Corp began to understand. With no god to run their world, what would happen? With The World losing its glory and credibility, there was only one choice left to the management of CC Corp: the rebirth of Aura. And with this grand plan, Project GU was born.
