Call of the Tempestarii is an optional solo-only Quest, released in Update 30.0 (2021-04-13). Corpus captain Vala Glarios attempts to seek out the Tempestarii, a vessel which was lost to the Void during the Old War.
Synopsis[]
Cephalon Cy discovers Corpus convoys exploring Void anomalies in Veil Proxima and decides to bring the Tenno along to investigate. Upon arrival, the Tenno gets intercepted by Vala Glarios and her fleet, followed by the ghost ship the Tempestarii, helmed by Sevagoth's Shadow. Escaping the ambush, the Tenno infiltrates a Corpus ship and hacks into their data vaults to discover the mysterious origins of the ghost ship. With this information, Cephalon Cy releases a distress signal to summon the Tempestarii and establishes communication with the ship. Vala returns to destroy the Tempestarii, but Sevagoth's Shadow fends off the invaders. The Tenno successfully sends Vala's capital ship into the Void and returns the Shadow to its body. In the end scene, Parvos Granum is seen with Vala in the Granum Void.
Walkthrough[]
This quest can be accessed directly from the Codex, after owning a Railjack and completing the The Deadlock Protocol and being Mastery Rank 4.
The player will receive an inbox message from Cephalon Cy, informing the Tenno that the Corpus are mobilizing towards Void Storms and they should investigate in their Railjack.
Intercept Corpus shipping convoy (Arc Silver Lvl 15-18, Veil Proxima)[]

The Tempestarii
The Tenno travel to the Veil Proxima to scavenge resources from wrecked ships. During the Void jump, a ghostly Void Railjack passes by the cockpit, which Cy initially dismisses as a visual sensor glitch. After gathering from one spot, several Vorac Basilisks and Gox Scavengers will appear and must be fended off.
After the third scavenge, a Corpus Ship comes into view and its captain, Vala Glarios, introduces herself as a servant under Parvos Granum. Shortly after, the same Void Railjack emerges from the Void Storm, which Vala recognizes. As the Void Railjack is hostile to both Tenno and Corpus and invulnerable to fire, Cy has the Tenno's Railjack evacuate and activates a Void jump, suggesting they find what Vala knows about the Void Railjack.
Infiltrate Corpus archives (Seven Sirens Lvl 17-20, Pluto Proxima)[]
Automatically transitioning into the Pluto Proxima, the Tenno infiltrates the Corpus Ship in a Spy mission where all three vaults must be hacked. Cy learns the Void Railjack was an Old War rescue ship called the Tempestarii, but disappeared into a Void Storm during a mission. A Somachord fragment can be found above one of the spy vaults.
After regrouping at a Dry Dock, Cy believes that the Tempestarii is searching for its final rescue mission and suggests delivering it a distress signal.
Signal the Tempestarii (Obol Crossing Lvl 21-24, Pluto Proxima)[]
Deep within a Pluto Proxima Void Storm, Cy launches a distress signal to summon the Tempestarii. The Void Railjack turns hostile after Cy responds to it incorrectly, prompting the Tenno to hold out until he can reestablish communications. After Cy successfully appeases the Tempestarii, the Tenno must then board it. A Somachord fragment can be found in the Tempestarii's forge area.
The Tenno meets the Tempestarii's captain,
Sevagoth's Shadow, who gives them the corrupted navigation data of their final rescue mission. The Tenno starts repairing the data via Parazon but Vala appears. She thanks the Tenno for subduing the Tempestarii before knocking them out.
The player now controls Sevagoth's
Exalted Shadow in a void space against waves of Corpus enemies, and will instantly revive on death. During this, they learn that Vala was the sole survivor of a Tempestarii attack, dreaming that the fragments of her dead crew were singing, thus seeking revenge against the Void Railjack. After the song ends the Tenno awakens, protected by Sevagoth from Corpus boarders, as the Tempestarii is seized by a beam generator.
The Tenno must board the Corpus vessel to destroy the beam generator. After hacking a console, they must fend off Jamming Drones (Taro Secura Ospreys) and an Optio. Once all are defeated and the hacking is complete, they must interface with a final console to destroy the station.
The Tenno must then return to the Tempestarii and repel Corpus fighters until it readies an Ordnance. The countermeasures tears apart Vala's ship. Vala charges her sisters with the duty of avenging her.
Cy directs the Tenno to finish the Tempestarii's final mission, triggering a jump into the Void to retrieve a lifepod. This lifepod contains the corpse of Sevagoth, who created his Shadow to continue piloting the Tempestarii and search for his body. Now reunited, Sevagoth is given a ship burial as his body is launched back into the Void. Meanwhile, Vala emerges in the Granum Void as Parvos Granum appears before her, extending his golden hand.
The player will receive Sevagoth's blueprint. They will also receive an inbox message containing the Tempestarii Railjack Skin, Sevagoth's Prex and Sevagoth Statuette Orbiter Decorations, and The Cold Below Captura scene. Additionally, if the player has completed The War Within, they will begin to encounter Candidates upon qualifying for minimum rewards in the Granum Void, who can be mercied to generate their own Sisters of Parvos.
Notes[]
- Players who already have a fully built
Sevagoth prior to completion of this quest will additionally receive a Riven Mod. - Upon completion of "Intercept Corpus shipping convoy", a Void jump will automatically transition directly into "Infiltrate Corpus archives" without docking. Should the player fail or abort the second mission, it will appear in the World State Window.
- Somachord Fragments can be found in the second and third missions, with predetermined positions. The fragments must be scanned in mission order; if players miss a fragment, they are required to replay the quest, as subsequent fragments will simply not appear. Sleeping In The Cold Below only requires two scans.
- Infiltrate Corpus archives: Random location in the Corpus Ship tileset.
- Signal the Tempestarii: The player's Railjack's or Tempestarii's forge area.
Trivia[]
- Call of the Tempestarii is the first quest that involves Empyrean missions.
- Tempestarii (singular Tempestarius) were medieval weather-making magicians who allegedly possessed the power to raise or prevent storms at will, alluding to the titular Railjack being bound to Void Storms.

Railjack could be good. Just need a level designer that isn't in to bdsm.
And how pray tell me player who has clearly played soooooo much railjack how its bad with more words than just "it bad"???
Are we not gonna talk about the fact that Tempestarii's forward artillery is about twice as fast to charge up as ours, and we never get a single mod or anything to enable ours to match it???
I'm serious! Go replay the quest, jump in the forward artillery seat at the part where you get to actually control it, and notice how much faster it is compared to our forward artillery
Wow its almost like its an ACTUAL orokin era ship and not a wrecked one thats been pieced back together.
I just came here to say the song is pure cringe.
Thank you for coming to my TED talk.
You're cringe
What is the Tempestarii's railjack class?
Ghost Ship
The song in this is cringe and bad. Also all the sisters are ugly.
The song isn't cringe my dude, it's just corpus version of sea shanties, and sisters can be ugly, but that's what parvos wanted, he need a sister at his side, and we just killed them for weapons, ephemeras, and hounds
I think the song is pretty good
But yeah the sisters look hedious, DE needs to fix how they make faces in the game
Next Update i also want fuckable Kuva Liches! What do you mean we don't play a Dating Sim with pretty people?!
Can we get grineer aids by having seggs with kuva liches?
So there's no info about the turret weapons the Tempestarii had during the quest? I guess they're unobtainable anyway i mean it's a turret that fires projectiles with lock on which is practically unable to overheat.
About the trivia "Probably due to the unique way of how this quest progress, completing the spy mission will not contribute to Nightwave acts related to spy missions." It's false because I actually got progress towards "Complete a spy mission" on Nightwave. I would have taken a picture but I didn't know at the time and I only read about this wiki page after I did the whole Call of the Tempestarii quest.
Who thought it was a good idea to have a solo-only railjack mission? Doesn't that kind of defeat the point? You're supposed to be a full crew, because face it, one person can't manage a whole ship efficiently!
Just finished it solo. Entry level railjack with an MKIII nose gun and plexus of rank 7. After a few failed "infiltrate Corpus ship" missions had to hire just one crewmate with Repair 5, to have an engineer repairing my hull damage. After that, the quest went smoothly.
Maxed out my Plexus during the the last mission, incinerating waves of enemy fighters, before I finally found the Ordnance button, lol.
I'll be real i did this once i got the railjack. no npcs no nothing no cap.
Lol, the railjack mission are basic solo, git good my brother!!
Me who did it solo with no crew mates because I don't know how to get crew mates.
Why would they give Sevagoth a burial if he's a warframe, supposedly controlled by a Tenno? If not, then is his shadow technically an umbra, since it can act on its own?
Yeah
It got defeated
Warframes were at some point humans (or are a copy of a human).
In quest it was clearly said that Sevagoth lingered on last amounts of energy and the moment he connected with his shadow, he stopped functioning.
Im actually very annoyed annoyed that my somachord doesnt have sleeping in the cold below
Me too
U didnt scan a tone fool
I'm sorry, did someone drank to much maple syrup and started hallucinating that they're making Disney's movie?
This made me laugh A LOT.
You're amazing!
We need more Railjack quests
Man I'm done making edits on this wiki. Everything you do is undone by some rando that has a better idea and doesn't have the decency to discuss altering what you've just done. Go ahead making this wiki more confusing for people. I'm out. F you for wasting my time.
Cry more
More community cancer saying hi.
Nature of all wikis sadly, once they get big enough.
So you made a factually incorrect edit, which was then reverted with a comment explaining exactly why, and instead of it being your fault that you made a shit edit and are too stupid to check the history, you blame the community?
The part where you kill stuff to the music was pretty cool tho.
Meh, it wasn't and you don't even have to do anything during this part of the mission. Last time I played it I just drank some coffee tabbed out waiting for it to be done. I like the music of the song, but the singing gets on my nerves.
Aeons what crawled up your ass and died?
Because I think the song is awful there's something wrong with me?
I get it i wish there was a good instrumental version
What is the railjack gun you fire when you're piloting the Tempestarii? Is it just exclusive to his ship?
I hope they are gonna add this gun eventually, i loved it!
Yeah, very powerull
Not much but atleast it’s homing shots.
Kills with two shots ¯\_(ツ)_/¯
Lmao, signal the tempestraii completely shit itself for me, didnt spawn the enemies and i was just trapped in the void
How weird. You don't have to kill anyone in this part. You just wait for the song to be done.
Take your own advice
Wow the French page is way more pretty
PDM
IT ESCALATED QUICKLY
It was pretty cheap.
Every time I click to start the quest from the navigation screen this is what I receive:
Could not Find an Open Squad. Please try again, or launch a new session from your personal Railjack stationed in a Dojo's Dry Dock.
Have gone to my railjack and get the same message.
Try doing it solo?
Found the problem you need the reliquary key
Lolololololololololololol
@excaliburRekt
It isn't the Reliquary, It's either Internet connection issues or no one is playing railjack at the time
