Starfield The Devils You Know Mission Walkthrough

Gather information on an individual who is possibly committing horrendous crimes in Starfield.

The Devils You Know is the sixth mission from the UC Vanguard storyline in Starfield. After gaining the trust of the United Colonies, it is time to learn about the unexpected secrets hidden behind the walls of the United Colonies. It is an optional side mission, completing which will reward you with 150 XP and 3000 credits


Completing the mission grants you The Devils You Know achievement. It is the second one out of the three unmissable trophies of the UC Vanguard questline.

After getting your citizenship at the end of Friends Like These, you will be sworn to Deputy Macintyre to keep the next clandestine meeting a secret. Take the elevator down to Subsection Seven in the UC Vanguard HQ in New Atlantis. A man by the name of Vae Victis will want to speak to you. He is the only person who can help you gather enough information about the Terrormorphs.

Vae Victis will ask you to track Dr. Reginald Orlase and gather the required evidence against the Terrormorphs before ending his conversation.

Optional: Speak with Deputy Macintyre

If you are not entirely convinced by Victus’s words, he offers you to run it by the UC executives.

When the conversation ends head over to speak with Deputy Macintyre to tell her about your conversation with Vae Victis. She will then approve of tracking Dr. Reginald Orlase but asks you to bring him back alive for further interrogation.

Speak with Captain Marquez

The next step to complete The Devils You Know mission in Starfield is to speak with Captain Marquez on the Den Space station, located in Chthonia planet of the Wolf Star system.

Captain Martinez will provide you with information about Dr. Reginald Orlase and give you the location of the Warlock ship which Dr. Reginald is suspected to be piloting.

Destroy or Disable the Warlock

The Warlock will be near the asteroids around Etherea in the Wolf Star System. Be warned though, that the ship will start attacking you as soon as you get near it.


Keep a few extra ship parts on you just in case you need to repair your ship during your battle with the Warlock

The Devils You Know quest in Starfield will give you two ways to deal with the Warlock. You can either target the Warlock’s engines to disable it and then board it to reach Dr. Reginald. Or you can destroy the Warlock completely.

This choice, however, won’t change the end of The Devils You Know faction quest in Starfield as Dr. Reginald will take his own life when you disable the engines of the Warlock ship. Dock with it and board the Warlock to arrest Reginald. Even if you board the Warlock, you can’t access the cabin as it is locked.

In our case, the game showed that I needed the Warlock cabin key to open it but there was no location on the ship that had the key. Simply reloading the game from a previous save removed that prompt so it must be a bug. In any case, the door automatically opens up once Dr. Reginald kills himself and you can enter the cockpit of Warlock in Starfield.

It is better to just destroy the ship as you’ll still get the evidence rather than seeing a dead body of a man in a disabled ship. If you destroy Warlock, you can collect the evidence from its debris. However, if you board the ship, simply search Reginald’s body to collect the evidence in The Devils You Know quest in Starfield.


You cannot steal or acquire the Warlock ship for yourself. Even if you disable the systems and try to pilot it, you will get the Unauthorized error message.

Deliver the evidence back to Vae Victus

Once you’ve gathered the evidence, head back to Subsection Seven to speak with Vae Victis. Give him the evidence you just gathered from the Warlock Ship. Vae Victis will examine the evidence and provide you with the name Kaiser.

This officially marks the end of The Devils You Know faction quest in Starfield and begins the next faction quest known as War Relics.

The Devils You Know mission bugs and fixes

The Devils You Know has unfortunately a couple of bugs that can impact your progress. Here are a few tips you can try to fix these issues.

Unable to progress after destroying Warlock

This bug appears after destroying the Warlock ship, where a cut scene plays out after which the game reloads the AutoSaved file. There has been no official solution as of yet.

The only workaround is to disable it and try boarding the ship instead. You can also go back to an old save file to see if the issue resolves itself.

Unable to start the next mission

After completing The Devils You Know mission, some players will not get the War Relics mission, letting them believe the quest is bugged.

The bug is caused if you assaulted the people of 1-of-a-kind Salvage on Niira, even if it was for a bounty mission. You will need to reload an old save where the 1-of-a-kind Salvage settlement remains unexplored, however far down that may be.

You can also revisit the quest during the New Game Plus version if you would rather not lose your current progress.
