The Unum chooses Nakak to receive a strange mask. A mask that leads to even stranger visions. What lost story does the Unum want to tell?

—Quest Description

Mask of the Revenant is an an optional quest that revolves around a decorative mask for the Operator. The mask tells the tale of a warframe left behind to prevent the return of the Sentient Eidolon, and upon completion: rewards the blueprint for the Revenant warframe.


The quest can be initiated from the Cetus vendor Nakak once the players have achieved the Observer (second rank) with The Quills, and has talked to her with the "Mask?" prompt. She will inform the player that she received a strange mask, called the "Mask of the Lost One", from Onkko, and will sell it for 1 Cetus Wisp.

The player must equip the Mask of the Lost One on their Operator and head into the Plains of Eidolon at night. They must then follow the marked white waypoint at the southwest side of Gara Toht Lake. Spotting a large spectral being that vanishes, the player must look around in Operator mode for a small blotch of energy with a hand reaching out from it. Nakak will then receive a vision from the Unum, explaining that the lake is where Gara had felled the Sentient, and a warden was placed to prevent the Sentient from resurfacing until the warden was lost.

Nakak will ask the player to rebuild "the lost one", mentioning that the Grineer have found relics and suggests talking to Konzu. The player must now initiate a Bounty until they find and build a part of the Revenant warframe.
If the player already has one piece of the Revenant warframe, Nakak will tell the player to proceed.

The player once again must return to the Plains of Eidolon at night. The white waypoint directs the player to the northeast side of Gara Toht Lake, where the specter appears and the player must interact with another small blotch of energy. Nakak sees another vision from the Unum, mentioning that the warden continued to strike down the Sentient until it briefly hesitated at one point.

To proceed, the player must return to Bounties to find and build another part of the Revenant warframe.

The final blotch of Sentient energy resides on a river between Gara Toht Lake and Renthi Spring, and again is only visible during the night. Nakak receives one final vision where the lost one extended a hand to the Eidolon, allowing it to emerge, dragging the warframe into its place. Just as Nakak finishes the tale, a Revenant Specter appears and begins attacking. Nakak tells the player to defeat the specter that serves as the mask for the Eidolon. Defeating the Revenant Specter will yield the blueprint for the Revenant Warframe.

After building Revenant, Nakak warns the Tenno that she had a dream of a new Eidolon emerging and they will need this Warframe's power to combat the new threat.


  • Originally this quest was not listed in the Codex, until Update 23.10.
  • Mukha (मुख) is Sanskrit for "face", both rather fitting by virtue of being Nakak's cousin, and ironic as he is only mentioned through dialogue.
  • The Fragments acquired in the mission depict a new Eidolon type that was announced in Devstream 100, with Nakak's final words foreshadowing its emergence.
  • If players are having trouble defeating it, the Revenant Specter fought in the last stage of the quest can be cheesed in various ways. These include luring Eidolon Vomvalyst enemies to its location, as they will attack the specter, which will fight back but has no way to damage them in their spectral state; or by simply using an Archwing Launcher to fly outside the reach of its Phantasma’s shots and repeatedly headshot it with a sniper or bow weapon.
