Sentinel: Descendants in Time Hints
I know the associations, but how does that help me solve the puzzle?
1 of 16: How did you cause the water in the moat to be raised?
2 of 16: You had to set the levers on seven of the machines to the "1" position before the glass cover over the water control handle would be raised.
3 of 16: So seven seems to be the "magic number" here. You'll need to use that handle to raise the water level in the moat, and you cannot get to the handle until you set exactly seven of the 12 levers.
4 of 16: And unless you picked exactly the right seven the very first time, you have probably already seen the moat get overfilled, and the platform floating too high.
5 of 16: Did you ever find a combination that would send water into the moat, but NOT have enough to raise the floating platform high enough?
6 of 16: No -- so that means that when you pick the WRONG levers (even if only one is incorrect), the result is to fill the moat with TOO MUCH water.
7 of 16: Or, another way to look at it is that if the wrong water-control unit is activated -- even by a single lever -- too much water will flow into the moat.
8 of 16: Thus, you will need to choose seven levers that activate only the correct water-control unit -- and not the other.
9 of 16: Looking at the associations between the 12 control machines and the two water-control units, you should be able to see that they are not evenly divided between the two water-control units.
10 of 16: In fact, 5 of the control machines are connected to the right-hand unit, and 7 of the control machines are connected to the left-hand unit.
11 of 16: So how can you set 7 levers without setting an incorrect lever?
12 of 16: The only answer is to set the 7 levers that correspond to the same water-control unit -- which, it turns out, is the unit on the left.
13 of 16: When you set the correct 7 levers, the position of each of the 12 red dial-switches is unimportant. The sole purpose of those large red wheels was to identify which control machine works with which water-control unit. Once that identification has been made, you only need to set the correct 7 levers.
14 of 16: Once the 7 levers are set, the cover on the water-control-unit activation handle will raise (as it does when ANY 7 levers are set to the '1' position).
15 of 16: Clicking on the handle now should cause the water to raise to the proper level, and raise the floating platform level with the walkway.
16 of 16: You can now cross the platform to get to the inside of level '1'.
