Introduction
Before you can fully access all the content available in the city of Fortuna, you have to complete a quest called “Vox Solaris.” This is a simple quest that introduces you to some of the characters of Fortuna and their plight thanks to the tyranny of Nef Anyo. There are no requirements for the quest so thankfully you can jump right into it as soon as you have access to Fortuna on Venus. While Warframe and weapon choice is not too important, you might find the quest easier if you use a Warframe with decent AoE or defense capabilities such as Equinox, Saryn, Limbo, or Frost.
We have two guides for you to use: The quick guide and the full guide. The quick guide is mostly for veterans who just want to get an idea of what the quest is like and want to know what the next step is so they can finish the quest as quickly as possible. The full guide has pictures for each step along with lore and provides a little more detail on the steps provided in the quick guide. Feel free to use whichever you prefer!
Quick Guide
Estimated Quest Completion Time: ~30 minutes
- Talk to Eudico at end of Fortuna by entrance to Vallis
- Talk to Thursby
- Head out to Orb Vallis (make sure you have Archwing Launchers equipped if you have them since they’re infinite and instantaneously deployed now)
- Go to Waypoint – You’ll have to collect 3 Corpus Caches. These caches show up on your map if you have loot radar mods and make a slight humming sound when you’re closeby.
- Once all 3 caches are collected, go to next Waypoint and kill drone.
- Eudico will hack the drone. Defend it by killing 30 enemies. AoE Warframe can make this part quicker. Even though this is a low level quest, you shouldn’t get careless as Corpus can deal heavy damage.
- Return to Fortuna
- Talk to Thursby
- Talk to The Business
- Head back to the Vallis
- Go to Waypoint and hack into terminal to deactivate lasers
- Hack into terminal inside room to obtain hitlist
- Head to next waypoint and investigate 4 dead bodies there
- Head to prison block and hack into the terminal there
- Wait for the hack meter to reach 100% progress. Terra Jailers drop data keys which speed up the hacking process – they are marked by red enemy icons.
- Return to Fortuna
- Talk to Eudico
- Go back to Orb Vallis
- Head to Waypoint. You’ll be greeted with an excavator. Power cell carriers may take a while to arrive, but should start arriving in large quantities after roughly 30 – 60 seconds. AoE or Defense Warframe like Equinox or Limbo can help here, but isn’t necessary as excavator has high health.
- Once excavation is completed, head to waypoint and let dialogue finish about coolant tower failure
- Return to Fortuna
- Talk to Eudico and agree to help Solaris United
- Head back to Vallis. Prepare yourself for many Corpus as soon as gates open.
- Rush to plant K-Bomb at designated area, then kill as many Corpus as you can.
- Return to Fortuna once prompted to do so by Eudico
- Talk to Eudico again
- Return to Orb Vallis
- Mount K-Drive in front of you and boost past the Profit-Taker Orb (sprint key to boost)
- Hack into terminal and prepare for defense
- Defend terminal while overheat progress bar increases. Warframes excellent at defense such as Limbo or Frost can make this part a breeze.
- Administer the Amarast once prompted at the terminal by the coolant tower
- Return to Fortuna – Quest complete!
Eudico and Thursby

To begin the quest, talk to Eudico who is located near the end of Fortuna (keep following the path from the entrance – you’ll see a large crowd of players surrounding her likely). She’ll talk about Thursby, a member of the Solaris that inherited his parents crushing debt. He’s at risk of having the dreadly “repo squads” come after him since he has nothing to his name, so Eudico sends you off to help the poor fella.

Thursby discusses his rather dire circumstances with you. After you inform him that Eudico sent you to help, he suggests stealing some supplies from the Corpus so he can stock his shop. He also briefly mentions that Eudico used to be known as Vox Solaris, the voice behind the rebellious group Solaris United. Nef Anyo attempted to identify her by presumingly torturing and “disassembling” the Solaris members of Deck 12. This silenced the “Vox Solaris” side of Eudico forever as she feared Nef’s retribution. Once you finish talking to Thursby, you’re directed to head out to the Orb Vallis for the first time.
The Orb Vallis – Helping Thursby
Note: Archwing Launchers now have infinite charges and are instantaneous, so it’s highly recommended to have them on your gear wheel to traverse the Vallis!
Your first mission out on the Vallis is relatively simple: Find and loot 3 Corpus supply caches in a small area. These supply caches show up on the map if you have any loot radar and also hum similar to resource caches on Sabotage missions. You have 8 minutes to find the 3 caches so you have plenty of time to find them even if you don’t have loot radar mods. Make sure you grab the Ayatan cyan stars and other loot that comes inside the caches!

After you find all 3 Corpus caches, Thursby gets a little overzealous and spouts about how you, the Tenno, could really hit Nef where it hurts by blowing up a coolant tower. Unfortunately, he does this over an unsecured channel and a Corpus spy drone overhears his blasphemous statements. Eudico waypoints the Corpus spy drone for you which you first must take down, then defend the hacked drone from enemies. While the enemy levels for the quest are low, you shouldn’t get complacent as they can deal heavy damage if you aren’t paying attention.
Helping “The Business”
Once you’ve finished defending the Drone, you’ll be asked to return to Fortuna. There you’ll find Thursby is quite happy, despite Eudico’s reprimands, as he can now start up his shop and avoid repo. At the end of his conversation with you, he’ll mention that “Biz” wants to speak with you.

The Business (‘Biz’) is vague in his initial conversation with you, mentioning the delicate balance in his life between preservation and destruction. Fortunately, you learn his intentions quickly once he sends you out onto the Vallis. He informs you that the head of the Corpus repo squad has made a hit-list for indebted Solaris. Biz wants you to take care of this repo squad leader with a friendly little K-Bomb. Eudico immediately rejects and instead wants you to take care of the situation “quietly.” Your first objective is to steal the hitlist.
This part is straight forward – Go to the waypoint and hack your way in and retrieve the hitlist (cyphers work). Eudico scans the hitlist and finds that the repo squad is going to hit Biz’s field team today. Biz rushes you to find his field team as quickly as possible, but unfortunately you’ll find several members of the team already dead once you reach the waypoint. Biz notes that this isn’t the whole team meaning the others might be alive. Investigate 4 of the dead bodies to discover the location of the remaining field members.

The remaining members are all located in a prison block awaiting “processing” by the Corpus. Hack into the prison block terminal and you’ll begin the next section where you have to wait for the hack meter to reach 100%. You can speed this part of the mission up by killing Terra Jailers which drop data keys that expedite the hacking process. These Jailers are marked with red enemy icons and are dropped in frequently, so make sure you hunt them down!
After the hacking meter reaches 100%, Nef Anyo informs you he’s aware of your actions and sends some of his repo squad after Thursby. Eudico frantically pleads for you to return to Fortuna as swiftly as possible, but it’s too late and the Corpus get to Thursby.
Helping Eudico
Once you return to Fortuna, you’ll find Eudico located in Thursby’s shop. She is frustrated that she couldn’t protect Thursby, informing you that the medics aren’t sure they can stabilize him with so much of him “missing.” She’s certain that it was a mistake to let you get involved and is now fearful of Nef’s wrath. However, she thinks it’s possible to still impress Nef before his grand unveiling of the coolant tower and wants you to help fix the “mess” you made. Off to the Vallis again!
Head back onto the lift that leads to the Vallis. Eudico will inform you that her engineers need a mineral called Amarast to counter heat cascade from the coolant tower. Biz reprimands Eudico for trying to please Nef, pointing out that no action will ever make Nef “kind.” At this point, you’re sent to an excavator on the Vallis which are extracting the Amarast mineral required for the coolant tower.

This portion of the mission is no different from any Excavation mission, but you might find it easier if you have a Warframe with decent AoE abilities. Power cell carriers are infrequent at first so don’t fret if the excavator reaches 0% power. The power cell carriers will come in larger quantities soon after you reach the excavator so just keep defending until then.
Once you’ve finished extracting the Amarast minerals, you’ll be sent over to the coolant tower. However, Nef wants to do a test run before the big presentation tomorrow and he activates the coolant tower without the Amarast. As expected, the tower does not work as intended and Nef blames the Solaris for the failure. He commands Eudico to present him with 50 workers of low efficiency for repo in an hour.
Vox Solaris Reborn
This is the last straw for Eudico who realizes the Business was right and someone must stand up against Nef Anyo. It’s time for payback! Once you decide to help, Eudico will hand you a “present” for the Corpus Taxmen before sending you back onto the Vallis. As you travel up to the Vallis in the lift, Biz is furious with Eudico before he realizes that his K-Bomb is missing. The lift doors open and you’ll find yourself greeted with dozens of Corpus and a convenient area to set off the K-Bomb in the middle of all of them. It’s slaughtering time!
As you kill countless Corpus and enjoy the sweet taste of karma, Vox Solaris (Eudico’s alter ego) begins making demands of Nef on behalf of Solaris United. While defending the gate, a huge robotic spider called a Profit-Taker Orb will start marching your way slowly. You’ll quickly find its invincible and it forces you back down into Fortuna. On the lift, Eudico and Biz have a nice heart-to-heart as they finally go back to their Solaris United roots.

It’s Hoverboard Time!
Talk to Eudico and she’ll tell you she arranged a “little something” for you to deal with that “spida momma” (her words not ours). Yes, it’s time for what you’ve been waiting for: The K-Drive! Once you’re back on the Vallis, you’ll be greeted with both the Profit-Taker and a K-Drive. It’s time to live the dream of Tony Hawk Pro Skater in space!

Mount the K-Drive and rush past the Profit-Taker Orb using your boost (sprint button). If you’re like us, you’ll want to take your time getting to the objective so you can have fun figuring out this fun, whacky new vehicle! For now, just know that sprint provides you a boost and crouch let’s you grind on rails.
Make your way to the waypoint where you’ll be greeted a terminal by the coolant tower. Hack into the terminal and prepare yourself for another Defense objective. Stasis Limbo, Frost’s Snow Globe or any AoE Warframe can handle this portion of the mission with ease. As the tower overheats, Nef becomes progressively desperate and eventually acknowledges that without the Solaris, there is no Vallis. In the end, all of Nef’s precious investors desert him as they watch the system he built crumble before him. Justice has been served!
The final step is to administer the Amarast mineral to dissipate the heat cascade. The coolant tower returns to normal levels and the mission is a success! Eudico reflects that even if she wasn’t the one to bring Solaris United back, someone else would have in her stead. This is just the beginning and there’s plenty of work ahead for Solaris United. Return to Fortuna to finish the quest. Congratulations!

27 Sep 2022I had major difficulty when first starting this quest with only Earth and Venus unlocked, but it seems to me the more planets you unlock the easier of a time you’ll have. Easier still with a warframe that has AoE abilities and decent level stat mods. My familiar did most of the ad kills.

23 Oct 2020I have frost (prime) but its still soooo hard at the coolant tower overheating part.

13 Oct 2020Anyone else have three level 30 coolant raknoids spawn the moment you hack the coolant tower for the final part of the quest? Cuz I’m not sure what I’m supposed to do about them other than wait until I have ridiculously better weapons, since my current weapons weren’t even registering on their shield meter and their harassment ensured the console’s lack of shields and eventual death regardless of how quickly I killed the other enemies present.

cat_sed_echo
18 Aug 2019In the excavator part it seems like it runs out of power faster than normal excavator missions typically do. I kept failing this part until I realized that I wasn’t feeding it cores often enough. Got it first try afterwards.

18 Apr 2019is there a way to beat the talk to biz level? i don’t have money so i can’t buy a super cool war frame or awesome weapons but get crushed at the freeing the hostages part

11 Feb 2019Glitched at the part where you hack the prisoners out of the cell. Hacking the panel does nothing and the laser gate stays closed. Anyone run into that problem?
Fyrebird721
1 Apr 2019it takes time to fully hack and disable the lazors, so it becomes a “kill all nearby enemies but especially the Target Guys” type of thing
InsanityRex
24 Aug 2019You have to check the hacking rate ( below the mini map). Once it is at 100% the jails open up.

1 Feb 2019Me and MANY others get a bug at step 21 where the lift becomes disabled for some reason. Help would be most appreciated.

20 Jan 2019I can’t seem to finish the last part. Defending the coolant tower is too much. Any advise on lvl? I’m a new player and only have Volt (21), Mk1-Bo (20), Mk1-Kunai(16) and Mk1-Braton (20). Any other hints/tips?

21 Jan 2019OH dude it’s super easy! You just need to kill everything then let the excavator run out of power then pick up a battery and start over fresh each time a new wave spawns but it seems like they only spawn when you use a battery
