Dûl Incaru, the Eternal Return

Dûl Incaru, the Eternal Return is a Hive Wizard and a daughter of Savathûn, the Witch-Queen. Having infiltrated the Dreaming City through Riven's wish, she is responsible for the city's Taken curse and works with Quria to traps the Guardians in a 3-week time loop in the event of her own death. Unopposed, Dûl Incaru leads the Taken invasion from Mara Sov's corrupted throne world of Eleusinia so that her mother can access the Distributary and use it to empower herself to godly strength. She is often accompanied by her Darkblade bodyguards known as the Fatesmiths (Gaurog, Alak-Tor, and Ba-Kuur), whose presence shields her from harm and can even respawn moments after death.

Trivia

 * The eternal return hypothesis is a model of cosmological development which posits that the universe will re-enact the same series of events for eternity.
 * This is in reference to Riven's curse, specifically referring t, the curse would 'reset' the Dreaming City to when the curse was first afflicted, progressing until Guardians once again kill Dûl Incaru again, and again, repeating the cycle every three weeks, creating a kill battery for Savathûn and giving her unlimited power.
 * Dûl Incaru is the third child of Savathûn to appear in all of Destiny, after Balwûr and Malok, Pride of Oryx.
