Mass Effect - Keeper locations: How to complete the Citadel: Scan the Keeper Mission
Where to find all 21 Keepers.
Finding Keeper locations in Mass Effect is one of the first quests you come across in the Citadel.
The quest can be initiated in one of two ways - by talking to Chorban or Jahleed - and though it's not mandatory for the main storyline, it's a storyline we'll return to in the sequel. As well as this, it's a welcome early source of easy XP - and a handy way to get to know the Citadel.

How to start Citadel: Scan the Keepers by talking to Chorban or Jahleed
Citadel: Scan the Keepers can be initiated two different ways depending on who you talk to first: Chorban or Jahleed. This choice also affects the outcome of your interactions with both Chorban and Jahleed.
Talking to Chorban: Scan the Keepers
After Shepard, Counselor Udina, and Captain Anderson meet with the Council about Saren's involvement with the geth, Shepard runs into a salarian scientist named Chorban who is suspiciously scanning one of the Citadel keepers.
When confronted about his actions, Chorban explains that he is attempting to crack the mysteries of these unknown lifeforms. Chorban asks Shepard for a favor: take his scanner and scan all the keepers. You can either accept the mission or decline it.
If you accept the mission, at some point in the mission you will run into Jahleed, Chorban's former business partner, at the C-Sec Offices. Read the section "Talking to Jahleed: Jahleed's Fear and Jahleed's Secret " for more information about this encounter.
Talking to Jahleed: Jahleed's Fear and Jahleed's Secret
You can avoid talking to Chorban altogether and head straight to the C-Sec Academy to find Jahleed.
He will be in the C-Sec Offices logging a complaint to a C-Sec Officer about Chorban. When you talk to Jahleed, he will tell you that he suspects Chorban is trying to kill him and asks for your help. Jahleed sends you to the Lower Markets to confront Chorban on his behalf.
When you reach the Lower Markets, Chorban will ask you for the data. No matter the response, Chorban will have the two armed salarians attack you. Fight back and Chorban will surrender. He will tell you about his business partnership with Jahleed and their illegal plan to scan the keepers.
A few things can happen here. You can either:
- Agree to scan the keepers for Chorban and Jahleed
- Kill Chorban
If you agree to scan the keepers, the scan the keepers mission will start. Go back to the C-Sec Offices and tell Jahleed the truth about Chorban's actions. This will allay Jahleed's concerns and he will agree to analyze the data. You can then go about scanning the keepers.
If you decide to kill Chorban, you must then confront Jahleed. Go back to the C-Sec Offices and talk to Jahleed. You can tell him that you killed Chorban and he will plead for his life.
At this point you can either:
- Turn him in to C-Sec
- Take his credits and don't turn him in
If you turn him in to C-Sec, the mission ends and you cannot get it back. If you take his credits and don't turn him in, he will try to recruit you to scan the keepers. If you agree to scan the keepers, the mission starts. If you say no, then the mission ends.

Though you can scan the keepers in any order, we have numbered the keepers in a logical progression based on speaking with Chorban to initiate the mission. If you speak to Jahleed first, this guide can still be followed as you see fit.

Mass Effect Scan the Keeper rewards explained, and how the mission impacts Mass Effect 2
In the original Mass Effect, after collecting all the data you are rewarded 240 XP and 360 Credits on top of the 10 XP and 30 Credits you receive per each scan - you do not need to go back to Chorban or Jahleed to receive this.
During this mission, it is possible to level up a few times if you complete this in the early stages of the game. Though you will not earn enough Credits to buy any gear, adding points to your talents will be extremely useful.
In the Legendary Edition, the XP and Credits rewarded will vary due to a change in how experience is gained; for example, we received 17 XP and 50 Credit per scan, and 368 XP and 650 Credits upon completion.
In both versions of the game, this side quest has a minor impact on Mass Effect 2, provided you import your save. If you do not kill Chorban, then he will send you the findings of the scans as a message on Shepard's private terminal at some point in the game, titled 'Concerns RE: Keepers'.
