Sentinel: Descendants in Time Hints

I'm confused; can you give me a step-by-step solution for the puzzle?

  • 1 of 10: This solution is broken into individual steps -- two at each level.  The information is presented for each level, first listing the handle that lowers the grate that gives access TO that level (from the outer walkways), and then listing the handle that lowers the grate that provides access to the circular walkway down to the next level.  In this way, you can stop at any point, if you feel that you better understand what is going on, and you wish to continue on your own.  Or you can simply ride the elevator down, setting all handles at once, and then return to the top and walk all the way down!
  • 2 of 10: Beginning at the top level (level '5'), lower the second handle from the left.  This gives access to the walkway down to level '4'.
  • 3 of 10: At level '4' (in the elevator), lowering the third handle gives access TO the platform at level '4'...
  • 4 of 10: ... and lowering the fourth handle gives access to the walkway down to level '3'.
  • 5 of 10: At level '3', lowering the first handle gives access TO the platform at level '3'...
  • 6 of 10: ... and lowering the fourth handle gives access to the walkway down to level '2'.
  • 7 of 10: At level '2', lowering the first handle gives access TO the platform at level '2'...
  • 8 of 10: ... and lowering the second handle gives access to the walkway down to level '1'.
  • 9 of 10: At level '1', lowering the third handle gives access TO the platform at level '1'...
  • 10 of 10: ... and you're done!
