Ir Anûk, Deathsinger

"Look at you! Already you are grown, my daughter, already you are a wizard. Have I been away so long? Now you are Ir Anûk, and Savathûn cackles and rages at your brilliance. You have written eleven axioms describing the ascendant places, our throne world. You have announced that you will kill one of these axioms, as Akka would kill the truth, and in mantling Akka you will become a God, as I am. If you try it I may kill you, or I may applaud. Well done."

- Oryx

Ir Anûk, Deathsinger is one of Oryx, the Taken King's two daughters, created after Oryx cut a larvae in half. The Deathsinger sisters are first encountered in Last Rites, when the player is infiltrating Crota's death ceremony. They are found next to Crota's tomb and have to be avoided. Together with her twin sister Ir Halak, Deathsinger, she is encountered and killed in the King's Fall Raid in Threshold.

Biography
Ir Anûk and her sister Ir Halak were created from the same larvae cleft in two by Oryx's sword, Willbreaker. He praised them for their cunning and intellect, especially Ir Anûk, for her ambitious methods of apotheosis—she wrote out the eleven axioms which described the Ascendant Realm and plotted to kill one. Oryx commended her by saying he may kill her for trying.

Later, as Oryx wrestled with his worm, Ir Anûk and Ir Halak began to die repeatedly in a certain place, ostensibly for no reason. When asked what they were doing, they launched into a highly technical description that Oryx eventually forced them to conclude simply: "If we hide our deaths from ourselves, we become harder to kill." Thus came about the birth of the first prototype Oversoul. Oryx ordered his son Crota to watch his sisters, fearing they were trying to go to the Deep, and to learn cunning.

Unfortunately it was Crota who needed watching. He began to conspire with his sisters and thought rashly he too would seek for himself a power. Using his sword he cut a hole in the Ascendant Realm, and unwittingly let in the Vex, who mocked his attempts to contain them by simply Blinking away from him whenever he attacked. His sisters went to help him, Ir Anûk created an Annihilator Totem while Ir Halak called upon their fellow Deathsingers and they fought the Vex, who learned all too quickly how the Realm worked, and proved difficult to dislodge.

Later, in order to protect his Realm, Oryx built the Dreadnaught. Ir Anûk and Ir Halak built the weaponry and internal systems for the ship, allowing Oryx to concentrate his Ascendant power and obliterate any foe.

Finally, billions of years later, Ir Anûk and Ir Halak barred the way to their father by challenging the Guardians sent to kill him. As their father's last line of defense, they used their Deathsongs to fight and unwrite the Guardians. They were eliminated, and the way to Oryx, the Taken King was clear.

Trivia

 * Ir Anûk's Grimoire card can only be obtained by killing her in the Last Rites mission on the Moon, without revealing your presence. It does not unlock in the King's Fall Raid. Despite the player being able to kill both Deathsingers in Last Rites, they can still be found in King's Fall. An explanation may be that they both have Oversouls, as they were the ones to discover them.
