The Deadlock Protocol

The Deadlock Protocol is a solo-only side Quest, released in . Nef Anyo seeks to gain control of the Corpus by claiming to have found an heir to their Founder, Parvos Granum. 
==Synopsis==
The Corpus Board of Directors is indecisive. To prove that he is the rightful heir, Nef Anyo has been trying to find genetic proof of his ancestral ties with the Corpus founder Parvos Granum by finding his remains, which would allow him to gain control over the Board. Finding traces of Parvos's personal bodyguard , his search leads to the Granum Void where he has been sacrificing Solaris workers in order to see inside this interdimensional realm.
The Tenno follows one of these Solaris workers and discovers that Parvos has been alive since the Orokin Era, saved by Protea who traded her life to encase Parvos in the timeless Void. Turns out Parvos lured the Tenno into the Void in order for Protea to scan their Warframes and become functional again, as a Specter.
Nef decides to ally with the Tenno to stop Parvos and his Protea Specter from escaping the Granum Void, giving them ciphers to access Corpus files on Parvos. After hacking into Corpus databases in order to build the , Parvos's invention linked to Specter technology, the Tenno reenter the Granum Void, freeing the Solaris captives and defeating the Protea Specter.
However, Parvos successfully escaped into reality, laying out plans to restructure the Corpus faction or start a new philosophy under the pretense of "an impending threat from Tau", offering the Tenno a spot on his bargaining table.
==Walkthrough==
This quest can be accessed directly from the Codex, after completing the Saturn Junction and being Mastery Rank 4.
A short cinematic will play, where Nef Anyo has begun to restructure the Corpus fleet by invoking the "Deadlock Protocol": a contingency initiative in case the Corpus Board of Directors should ever be caught in a permanent voting impasse; having unsuccessfully voted seven times so far with seven directors for and seven opposed, again and again each time. The Tenno then receives a broadcast from Vox who announces that the power structure within the Corpus is failing and that it is Solaris United's time to rise.
===Decrypt Nef Anyo's Deadlock memorandum (Interception, Venus)===
Eudico contacts the Tenno informing them that the Deadlock Protocol is costing Solaris lives; Nef Anyo has claimed to have found an heir to the Corpus Founder, Parvos Granum, who can potentially unite the Corpus Board of Directors and bring about disaster to Solaris United.
This mission is a three-round Interception with only two towers. Eudico uses these towers to decrypt Nef Anyo's memorandum, where he explains his birth history within the Corpus before boldly claiming that he himself is the genetic heir to the Founder, and he only needs to prove this.
===Visit Eudico in Fortuna===
Eudico calls the Tenno to meet within the backroom of Fortuna. The Business introduces , a Warframe personally assigned to Granum by the Orokin themselves. Granum was assassinated, presumably by a Board member, when the Void drive of his personal transport was sabotaged, and Nef Anyo is searching for remains of Protea who was supposedly with Granum during his death.
===Learn the fate of missing Solaris ("Volunteers", Venus)===
On landing, The Business directs the Tenno to locate a Protean Sensor, which is a giant hand in gold, a tribute to the late Granum who was missing his left hand. They are interrupted by a Void-temporal shift and an announcement of Nef Anyo bringing in "volunteers". In order to understand the situation, The Business directs the Tenno to take control of a nearby Corpus Systems and then defend it.
The Tenno are then directed to another Protean Sensor. Upon arrival, they see a Solaris worker being vaporized by the hand, much to Eudico's shock. After defending the next Corpus Systems, the Tenno receives a live feed from the vaporized Solaris, who has been transported to the Void, much to Nef Anyo's delight.
===Return to Fortuna===
Back in the backroom, The Business reveals how to operate the Granum Tributes, using an item called a Granum Crown located somewhere on the Corpus ships.
===Beat Nef to Granum Void (Tributes, Phobos)===
While searching for the Granum Crown, Nef Anyo declares he is ready to send a Treasurer to make a tribute himself. The Tenno must intercept the Treasurer and loot the Granum Crown they drop, then make their way to a Granum Tribute.
Upon offering the tribute, the Tenno are transported to the Granum Void, discovering a very much alive Parvos Granum who has been preserved thanks to Protea's time-manipulating abilities, but has become but a Specter of herself. As the Tenno fight off Errant Specters, Granum does not deny that Nef Anyo is his son, but disowns him and rejects his twisted and selfish methods within the Corpus; Granum reveals that he had simply been using Nef Anyo to summon the Tenno. Protea had become reinvigorated with her kin, before promptly ejecting them from the Void with a . A time dilation brings the Tenno back onto the ship as if they had never entered the Void; a confused Business tells the Tenno to extract as the Errant Specters begin to appear.
===Acquire parts to build the Xoris (The Xoris, Europa)===
On the Orbiter, the Tenno receive an inbox message from an enraged and betrayed Nef Anyo, who is willing to call truce with Solaris United due to the threat of the Protea Specter: if the Tenno are able to defeat it, they in return will be able to rescue the Solaris trapped in the Void. To that end, he supplies the Tenno with a blueprint for the Glaive.
This mission is a Spy. All three vaults need to be hacked to obtain the Xoris Handle, Core, and Blade. The vaults reveal that Parvos Granum was developing the Specter Particle Theory, and used it to wipe out a Warframe strike force during the old Orokin Era. The Business declares that Granum's high intelligence could be seen as a threat to Solaris United.
===Use your Xoris to free Solaris captives in Granum Void (Parvos Granum, Neptune)===
With the parts in hand, the Tenno must build the Xoris in the Foundry. While crafting, The Business discovers that Granum may soon be capable of leaving his Void domain.
Returning to the Corpus fleet, Nef Anyo, declares the Tenno are too late as the Errant Specters have overrun his fleet. Unwilling to let his ships be captured, he breaks his deal with Solaris United and engages the self-destruct sequence on his ships. The Tenno is able to retrieve the Treasurer's Granum Crown and enter the Granum Void just before the ship explodes.
To save the three Solaris workers trapped within the Granum Void, the player must "charge" the Xoris by killing the Specter Particles with its melee attacks. After accumulating three charges, they must detonate the Xoris mid-flight via the Alternate Fire button near the Solaris worker.
After freeing the Solaris workers, the Protea Specter leaves her pedestal to do battle, armed with her signature sidearm and a . After depleting her health, she will activate to regain all her health; the player must stop this using the Xoris's discharge. The process must be repeated three more times to defeat the Protea Specter.
Upon defeating Protea, the Tenno are ejected from the Granum Void and are warped back in time, to the beginning of the mission, just before Nef Anyo decides to activate the ship's self-destruct. The Tenno extract from a confused Nef Anyo and his specter-less ship.
Upon returning to the Orbiter, Vox broadcasts for the Solaris to celebrate their united front with the Tenno. The player is rewarded a blueprint for the Warframe. Meanwhile, Parvos Granum delivers an inbox message to the Tenno informing them of his intentions to restructure the Corpus to counter the impending threat from Tau, otherwise, he will abandon his children to create a new doctrine, inviting them and Solaris United a seat at his new table, also awarding them the Granum Void Captura Scene.
