Warhammer 40,000: Rogue Trader

To unlock this, your Rogue Trader has to be a psyker. If you are not a psyker you will not get the special dialogue option to complete this the way the game wants you to in order to unlock the achievement.

You also have to find and correctly unlock/pass three perception checks in the area first. One is immediately up and to your right next to another spy glass bubble from where you start the area. The next is below (go down the ramp into the grass) and to the left from where you unlock the first. Close to where you start the area, the other set of red containers in front of your shuttle. The third is the other set of red containers just up from the second. Right before you inspect the bottomless pit. Once you pass all three checks and get the info, the dialogue option for your psyker RT will appear when you first inspect the bottomless pit. If you have already interacted with the pit however, or you failed one of the perception checks, you will have to reload before you landed.
