How to handle the pillars? Did the explorer have the right order? And how to enter data here?
Also I ruined the oil machine in the previous room--was that machine necessary? I don't have a useful save to redo it.

Spoiler!

Fix the pillar puzzle by following the message in the vision.
Then get rid of the Ethera by getting your crew up on the platform where he appears. Then Ryker. Then ?
