Irminsul has existed since the beginning of Teyvat's creation. Originally, it belonged to dragons, and the Ley Lines flowed with an abundance of a primitive form of elemental energy, the power of the Light Realm.After the war with the dragons, the Heavenly Principles usurped and refashioned Irminsul, transforming the primordial power of the elements into elements from the Human Realm. They placed it at the service of humanity and used it to anchor the fate of the world.The Frostbearing Tree is one of Irminsul's branches. It was shattered by a divine nail during.

Irminsul was infected again during. The forbidden knowledge spread to Rukkhadevata's own consciousness, so 500 years later, Nahida had to erase Rukkhadevata from Irminsul to stop its corruption. Since then, no one belonging to Teyvat remembers the Greater Ruler, not even Nahida herself.When Rukkhadevata was infected with forbidden knowledge, she broke off the purest branch of Irminsul and transformed it into its new incarnation, Buer. Buer can directly connect to Irminsul and process its data. Since her power and consciousness are linked to the tree, Irminsul's contamination can harm the Dendro Archon.

He split his soul into two, and when one was killed and merged with the Ley Lines without arousing the suspicions of the Dendro Archon, the second half was artificially implanted within Irminsul. Thus, the Harbinger's soul was able to merge within the tree.
