Last Wish

Last Wish is a raid released during Forsaken at the start of Season of the Outlaw. During the Awakening mission, it is revealed that the source of Uldren's corruption and madness was Riven of a Thousand Voices: the last known Ahamkara and architect of the Dreaming City. Queen Mara orders Petra Venj to open the gates and let the Guardians in, and tells the Young Wolf to assemble a fireteam and kill Riven as an act of both mercy and vengeance. Within the Keep of Voices, the fireteam encounters Kalli and Shuro Chi, two of Queen Mara's s who had been taken by Oryx during the Taken War, as well as Morgeth, the Spirekeeper -- a monstrous Taken Ogre that guards Riven's chamber. After defeating all three of Riven's minions and conquering the Vault, the wish-dragon reveals herself and is ultimately killed. However, after delivering her heart to the newly-freed Techeuns and effectively completing the raid, Riven speaks to the Young Wolf, informing them that through their actions, she has been granted enough power to grant one last wish, telling them that she cannot wait to show them what 'she' wished for. Riven then places a curse on the Dreaming City, causing it to be completely Taken and locking it in an eternal, three-week cycle, though this would not be revealed until The Shattered Throne was made available.

Prologue
"For generations, the Dreaming City housed one of the Awoken's most closely guarded secrets. She is known as Riven — Riven of a Thousand Voices. The last known Ahamkara. She has been Taken. And her death is your calling."

--Petra Venj

Kalli, the Corrupted
"Have you come to free the Witches? They will resist. Darkness is their shape now."

--Riven of a Thousand Voices

"You have my thanks, Guardians, but my sister remains enthralled. Without Shuro Chi, we cannot defeat Riven. Find her; save her. And know this: Riven WILL try to seduce you. When she speaks...Do. Not. Listen."

--Kalli

"I can give you anything. What is it you want? Weapons? Glory? Peace? Or is it simpler than that?"

--Riven of a Thousand Voices

Shuro Chi, the Corrupted
"Oh ho ho. You are so tiny. Yet you continue to make enemies of so many gods and monsters. You want battle. I'll give you war!"

--Riven of a Thousand Voices

"You saved my sister...thank you. Ahamkara feed on desire. Your desires could feed a nation of such beasts. They would grow till they shadowed the sun. Kill it. Rip out its heart. Bring it to us. We will purify it. Only then will Riven be contained."

--Shuro Chi

"You sully the sacred architecture of a culture you cannot understand. All so you can say you won today. Could that be what you’re driving toward? Do you have the audacity to wish for my death? Perhaps you and I can work together."

--Riven of a Thousand Voices

Morgeth, the Spirekeeper
"The Awoken kept me here for so long. A better fate than my kin suffered. But paradise is a prison when you cannot leave. I would so love to repay the hospitality of those who use my words to carve this city into the screaming surface of reality."

--Riven of a Thousand Voices

"There is no end to the Taken. You have stolen from them more than they could ever take from you. You are destined to fight forever."

--Riven of a Thousand Voices

The Vault
"You don’t hesitate to reach into the Deep. Your kind is so brave. Those with conviction pair best with my kind. Like you. Like the Awoken prince. Shall we be friends?"

--Riven of a Thousand Voices

"You’re so close, friend. Find me. Kill me. My heart is yours."

--Riven of a Thousand Voices

Riven of a Thousand Voices
"Ah, I've waited so long to fulfill one last wish."

--Riven of a Thousand Voices

The Queenswalk
"Fetch the heart! Hurry!"

--Kalli

"I am glad you did not heed her words. We will finish this. Riven of a Thousand Voices, architect of this city. Return to us -- for the sake of plans to come."

--Kalli

"It is done. We will meet you on the other side."

--Kalli

Epilogue
"I thought they'd never leave. You and I are not done. We're inseparable now. Through your actions, we've forged an age-old-bond between my kind and yours. One wish granted deserves another. And I cannot wait to show you what SHE asked for. O murderer mine..."

--Riven of a Thousand Voices

Aftermath
"My Queen commanded me to slay a beast. We could not do it alone, so I turned to the Guardians. Six brave heroes came to destroy my people's greatest secret… Riven. The last known Ahamkara. A creature of immense power and cunning. The Guardians killed Riven and ripped out her heart. But Ahamkara transcend death. They can transform desire into reality… even when they are nothing but bone and dust. I should have known that Riven would grant one last wish… one last curse. Now, the Dreaming City has been Taken. I opened the gates. I ordered the attack. I… should have known."

--Petra Venj

After the Young Wolf unknowingly wished for Riven's death, the devious Ahamkara was given great power, enough power to grant Savathûn's wish. A wish that would doom the Awoken forever and provide the scheming god with an infinite supply of power. The Dreaming City was Taken in its entirety, allowing Savathûn's Hive and Taken to join forces with Xivu Arath's brood and invade the Awoken stronghold. Dûl Incaru, the Eternal Return and Daughter of Savathûn would be the vessel from which the corruption originated, and she would make Eleusinia her home. However, the true extent of the curse would not be revealed until three weeks later, when the curse was at its full strength and when the Blind Well had opened the gateway.
