Mass Effect keepers look strange and are challenging to find. However, they do an excellent job keeping the Citadel’s systems and running smoothly. However, it isn’t easy to establish this since Council law prohibits them from interrupting their work. This is because they can self-destruct into a pool gloop if disturbed.
After your first encounter with the Council of the Citadel, you might have met a Chorban salarian while working through Mass Effect Legendary Edition. They are currently examining one of the Mass Effect keepers. If you approach them, they will explain the dubious legal studies they’re conducting before giving you a scanner and asking you to scan all keepers within the Citadel. If you can find the right places to look, they’ll give you a scanner and tell you were to scan every Mass Effect keeper in the Citadel.
