Biography
"Eir yearns for nurture. It does so through order." Billions of years ago, Eir and his siblings were trapped beneath the deep oceans of Fundament guarded by the Levithan. During their imprisonment they would be greeted by the Disciple known as Rhulk. Rhulk would convince them to pledge their allegiance to the Witness and would take their mother Xita, the Nurturing Worm from the deep oceans of Fundament to his ship. Later the heirs to the Osmium Throne, Aurash, Sathona, Xi Ro would travel to the domain of the Worm Gods while being guided by a dead worm larvae. The Worm Gods offered them power and immortality in exchange for becoming parasitized by their larvae. The siblings accept becoming Auryx, the King of the Hive, Savathûn, the Witch Queen, and Xivu Arath, God of War, spreading the larvae among their people. The Worm Gods oversaw the Hive's conquest of Fundament, providing knowledge, orders, and censure to their leaders as necessary. When the war freed the Worm Gods from Fundament's core, they responded by opening a wormhole into geostationary orbit, allowing the Hive to invade Fundament's moons and the Ammonite civilization that dwelled there.

After the death of Akka, Eir became the new patron god of Oryx, the Taken King. When the Vex invaded Oryx’s Throne World, Eir demanded he put his house back in order.
