Level: Dark Citadel
All four of these trophies are related to traversing the Dark Citadel. In no particular order, you can go through each of the challenges posed by the area, collecting all that you can, until you finally break the Sage out. The Sage will give you a Power Cell in exchange for releasing him, as well as start working on taking the shield off of the Precursor Robot in the middle of the Citadel.
