===Isu Era===
During the [[Human-Isu War]], several Isu factions became aware of an impending [[Sun|solar flare]] which would result in both the [[human]]s and Isu facing extinction. Realizing that a solution was needed to counter the oncoming coronal mass ejection, some Isu choose to ignore the war and instead focused on finding solutions to save [[Earth]].<ref>''[[Assassin's Creed III]]'' – Modern day</ref>

After many solutions had failed, [[Jupiter]], [[Juno]], and [[Minerva]]—the [[Capitoline Triad|latest triad]] to hold the titles of [[Father of Understanding]], [[Mother of Wisdom]], and [[Sacred Voice]], respectively—had come up with a seventh attempt which had a chance of succeeding. This seventh method was called Yggdrasil, a supercomputer which could store an Isu's essence and reincarnate it into the human gene pool across eons.

===Viking Age===
In 877 CE, [[Sigurd Styrbjornsson]], the human incarnation of Týr, was guided to the Yggdrasil chamber by visions of his past life. Accompanied by his adoptive sister [[Eivor Varinsdottir]], who was secretly Odin's rebirth, the two ventured into the mountains of [[Hordaland|Hordafylke]], where they found the entrance to the chamber inside a cave and Sigurd recited the words on the [[Saga Stone]]—a piece of the vault's door which had broken off—to gain access. Once inside the chamber, the siblings saw [[Svala]], the incarnation of Freyja, already hooked to Yggdrasil and proceeded to activate the machine, which brought them to a simulated version of [[Valhalla (afterlife)|Valhalla]].<ref name="A Brother's Keeper" />
 
[[File:ACV A Brother's Keeper 14.png|thumb|250px|Eivor and Sigurd entering the Yggdrasil chamber]]
After leaving the simulation, Eivor and Sigurd were confronted by their [[Assassins|Hidden One]] ally [[Basim Ibn Ishaq]], who was the incarnation of Loki and had followed them to the vault to take his revenge. Following a prolonged fight across the Yggdrasil chamber, Basim was defeated by Eivor and then forcibly hooked to Yggdrasil by Sigurd, trapping his consciousness inside [[the Grey]] for centuries.<ref name="A Brother's Keeper" />
 
===Modern times===
In August 2020, the Assassin [[Layla Hassan]] discovered the location of the Yggdrasil chamber from Eivor's [[Genetic memory|genetic memories]] and traveled there, hoping the supercomputer could be used to reverse a series of global anomalies caused by the activation of the [[global aurora borealis device]] in 2012. As Yggdrasil had been running for centuries by that point, the chamber was filled with lethal radiation emitted by the machine, requiring Layla to use the [[Staff of Hermes Trismegistus]] to protect herself.<ref name="ACV" />
 
After connecting herself to the machine and entering the Grey, Layla met the still-trapped Basim, who showed her how to slow down Yggdrasil and end the anomalies. However, this came at a cost, as Layla's consciousness became trapped within the Grey while Basim was released from his imprisonment. Layla accepted her fate and decided to help "[[Desmond Miles|The Reader]]" with running his [[calculations]] to prevent future cataclysms, while Basim used the Staff of Hermes to rejuvenate his physical body and left the Yggdrasil chamber.<ref name="ACV" />

Following the Great Catastrophe, the true purpose, design, and location of Yggdrasil was largely forgotten among the remaining human population. In time, it was passed down into myth, where it was reimagined as an immense ash tree that held the cosmos together, and became so important to Norse folklore that [[Vikings]] like the [[shieldmaiden]] [[Eivor Varinsdottir]] of the [[Raven Clan]] were known to [[tattoo]] it on their body.<ref>''Assassin's Creed: Valhalla</ref>

Patience, brothers. Soon we will reveal the secrets of Dawn of Ragnarök.

This article has been identified as being out of date. Please update the article to reflect recent releases and then remove this template once done.

"From the life-tree we go, to the life-tree we shall one day return."
―Odin to the rest of the gathered Æsir, c. 75,000 BCE.[src]-[m]

Yggdrasil, also referred to as the World Tree,[3] is an ancient supercomputer which was built by the Isu as an intended seventh solution to the Great Catastrophe.[1]

Mythology

In Norse mythology, Yggdrasil was interpreted as a literal titanic ash tree whose roots and branches connected all of the Nine Realms, which consisted of Asgard, Jötunheimr, Múspellsheimr, Midgard, Svartálfaheimr, Vanaheimr, Helheim, Álfheimr, and Niflheim.[1]

History

Isu Era

During the Human-Isu War, several Isu factions became aware of an impending solar flare which would result in both the humans and Isu facing extinction. Realizing that a solution was needed to counter the oncoming coronal mass ejection, some Isu choose to ignore the war and instead focused on finding solutions to save Earth.[4]

The Æsir using Yggdrasil to seed their DNA into the human gene pool

After many solutions had failed, Jupiter, Juno, and Minerva—the latest triad to hold the titles of Father of Understanding, Mother of Wisdom, and Sacred Voice, respectively—had come up with a seventh attempt which had a chance of succeeding. This seventh method was called Yggdrasil, a supercomputer which could store an Isu's essence and reincarnate it into the human gene pool across eons. However, disaster struck before they had a chance to use it, though nine members from the Æsir branch of Isu—Odin, Týr, Loki, Freyja,[2] Heimdall,[5] Thor, Sif, Frey, and Idun[6]—managed to upload their consciousnesses before the computer's laboratory caved in.[7]

Viking Age

In 877 CE, Sigurd Styrbjornsson, the human incarnation of Týr, was guided to the Yggdrasil chamber by visions of his past life. Accompanied by his adoptive sister Eivor Varinsdottir, who was secretly Odin's rebirth, the two ventured into the mountains of Hordafylke, where they found the entrance to the chamber inside a cave and Sigurd recited the words on the Saga Stone—a piece of the vault's door which had broken off—to gain access. Once inside the chamber, the siblings saw Svala, the incarnation of Freyja, already hooked to Yggdrasil and proceeded to activate the machine, which brought them to a simulated version of Valhalla.[2]

Eivor and Sigurd entering the Yggdrasil chamber

After leaving the simulation, Eivor and Sigurd were confronted by their Hidden One ally Basim Ibn Ishaq, who was the incarnation of Loki and had followed them to the vault to take his revenge. Following a prolonged fight across the Yggdrasil chamber, Basim was defeated by Eivor and then forcibly hooked to Yggdrasil by Sigurd, trapping his consciousness inside the Grey for centuries.[2]

Modern times

In August 2020, the Assassin Layla Hassan discovered the location of the Yggdrasil chamber from Eivor's genetic memories and traveled there, hoping the supercomputer could be used to reverse a series of global anomalies caused by the activation of the global aurora borealis device in 2012. As Yggdrasil had been running for centuries by that point, the chamber was filled with lethal radiation emitted by the machine, requiring Layla to use the Staff of Hermes Trismegistus to protect herself.[1]

After connecting herself to the machine and entering the Grey, Layla met the still-trapped Basim, who showed her how to slow down Yggdrasil and end the anomalies. However, this came at a cost, as Layla's consciousness became trapped within the Grey while Basim was released from his imprisonment. Layla accepted her fate and decided to help "The Reader" with running his calculations to prevent future cataclysms, while Basim used the Staff of Hermes to rejuvenate his physical body and left the Yggdrasil chamber.[1]

Legacy and influence

Following the Great Catastrophe, the true purpose, design, and location of Yggdrasil was largely forgotten among the remaining human population. In time, it was passed down into myth, where it was reimagined as an immense ash tree that held the cosmos together. Yggdrasil became so important to Norse folklore that Vikings like Eivor Varinsdottir were known to tattoo it on their body.[8]

In the late 9th century, Eivor used a psychoactive mixture made by Ravensthorpe's resident seer Valka to relive Odin's memories of his time in the dwarven realm of Svartálfaheimr looking for his captured son Baldr before Ragnarök began. In these visions, Odin often came across altars build around pieces of Yggdrasil's roots, where he could sacrifice a portion of his life force to recharge his Hugr-Rip.[9]

An Order of the Ancients medallion featuring the Yggdrasil symbol

Around this time, the members of the Order of the Ancients operating in Anglo-Saxon England carried silver medallions engraved with a depiction of Yggdrasil, which were used to signify their membership in the organization.[10] Later members of the Templar Order, the Ancients' successors, were also shown to sometimes adorn their outfits with Yggdrasil symbols, such as Shay Cormac and Juhani Otso Berg.[11] However, it is unknown if these symbols held any particular meaning or were purely esthetic.
