Why would she need a more primitive method of getting to layer five, there's a perfectly could navigator and set of beamers lying around.She had to of used a more primitive method of getting to Layer 5, and perhaps those beamers we see, are how she reached Layer 5. The beamers do open layers and other locations. She could have activated those during her transit.
Why didn't she take the navigtor in the first place? If it was just sitting there, why wouldn't she take it and use it to get to layer five?
A) She put it there for us. In which case, how did she get back to layer five after leaving it?
B) It was already there, and she didn't need it. Seems plausible, if she already had one of her own, there would be no need to lug another one around.
C) Mur put it there after Liz left. Could have been Mur, he was chasing Liz right? Why would he want us the have the navigator though, and similarly, how did he get back to layer five after leaving it?
D) A third party placed it there. Seems unlikely, there's no mention of everyone else anywhere in the game.
E) Other option.
EDIT:
I always had the impression that they were receivers of some sort.
That's what I was thinking. Like the fountain, the beams seem to be more wavy on these two devices. Maybe the beam becomes less stable over time.
