About the Reaper Control Rod-thingies, I have a better question - Placement.

If you look up after talking with the starkid, you'll notice the ball part of the Crucible above you, with the four prongs in the middle as seen in the cinematic, and that this thing you're standing on, is actually on the Citadel itself, underneath the base of the Citadel Tower.

Why? Why is there a device for controlling the reapers or wiping the synthetic life just underneath the tower floor? I understand the Crucible was adapted to use the Citadel by previous cycles, but '''Why. Are. These. Things. Part. Of. The. Citadel.'''

Did some Prothean just randomly notice "Oh look, there are actually buttons to destroy the Reapers beneath the Citadel Tower, nobody just noticed until now."
