Dûl Incaru, the Eternal Return

"Is my cyclical death not the very engine which brings you here, again and again, in hope of answers? Thus I do own the portion of your mind which you devote to truth's pursuit."

- Dûl Incaru to the Guardian

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 after the former's death and works with Quria to trap everything in a 3-week time loop upon her own demise. Unopposed, Dûl Incaru commands the Taken and Hive armies from Mara Sov's corrupted throne world of Eleusinia in an unending battle with the Awoken and Guardians, creating a kill battery for her mother's scheme for unlimited power. 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 resurrect them after death.

Gameplay
If Dûl Incaru or her Fatesmiths are shot by a Guardian, or one gets too close, the encounter will begin, where she will unleash her Fatesmiths and Taken Psion back-up. She will remain immune for most of the fight. On occasion, she will conjure a Void Crystal behind her, where ever she's positioned herself, which will shield all of her Fatesmiths; once the Crystal is destroyed, the shield breaks, but any killed Fatesmiths will be resurrected and more Taken Psions will spawn.

To deal damage to her, Guardians must kill the roaming Fatesmiths and collect their Finite Thoughts, which will allow 45 seconds of damage; the more Finite Thoughts collected (a maximum of 3), the more damage that can be done to Dûl Incaru (note, unlike Vorgeth's Petitioner's Mark, the timer cannot be reset). Once the timer hits 0, the players are killed, so it is advised that the players gather on the center altar so that they can be cleansed of the Finite Thought before it can fatally affect them. After the damage phase, the players should wait for Incaru to conjure another Crystal in order to summon the Fatesmiths once more and prep for another damage phase.

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 to 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.
