Sentinel: Descendants in Time Hints

I can get to the top of the light towers; but how do I solve this puzzle?

  • 1 of 17: It is impossible to provide an exact solution to this part of the Sanselard puzzle, for reasons of randomness, which will be apparent within the next few clues.  This particular thread will focus on the flow of what needs to be done to solve this puzzle, regardless of the randomness of the situation you may find yourself in.
  • 2 of 17: First of all, make sure that you take a moment to get a good "bird's eye view" of Sanselard.
  • 3 of 17: Focus your attention on the four light towers (one of which you are probably standing in, at the moment), as well as on the tower with the four dish antennae on top, and the four mechanical arms on its sides.  (This is marked with a green "X" on the Map of Sanselard.)
  • 4 of 17: What do you see happening?
  • 5 of 17: The four light towers are sending out period beams of light, each of which is targeted at one of the four dish antennae.
  • 6 of 17: And when a beam of light strikes any of the four dish antennae, the associated mechanical arm (i.e., the one on that side of the tower) is activated.
  • 7 of 17: Your goal -- and the eventual goal of this entire convoluted set of operations here in Sanselard -- is to get all four light beams (and, hence, all four mechanical arms) synchronized so that they are operating together.
  • 8 of 17: Each tower send out a light beam at identical frequencies.
  • 9 of 17: However, when you first arrive in Sanselard, the *phase* of these light beams is out of synch.  And that is what you want to adjust.
  • 10 of 17: The equipment at the top of each light tower is a control panel that allows you to adjust the "phase" of this particular light tower's beam of light.
  • 11 of 17: Experiment with the round control, and determine what is active.
  • 12 of 17: Note the 8 points around the outer ring of the control panel, which -- when clicked on -- will cause this particular light tower to adjust its "phase" (i.e., when the next beam of light will be sent out).
  • 13 of 17: When you adjust the phase, the time until the next beam will either be shortened or lengthened; but after that, the frequency of the beams will continue to be exactly what it was before.
  • 14 of 17: Think of walking next to someone, and the two of you are "out of step".  Your footsteps are occurring at regular intervals, but just out of synch.  Have you ever tried to either speed up one or two of your steps (or, conversely, slow them down) so that you are back "in step" with the other person?  That's exactly what you have to do here...
  • 15 of 17: ... except that, in this case, there are FOUR people walking together...
  • 16 of 17: ... and they are ALL "out of step"!
  • 17 of 17: When all four light beams are synchronized, and hit their antennae receivers at the same time, the mechanical arms will work in unison.  Watch the ensuing video for a clue to what to do next.
