Arrive at Tower Ruin, containing Book to J’Nanin, view of some power lines, access to rest of Island

 

Straight, past Cave entrance -> Next fork

Continue Straight -> down ladder, across bridge to CONTROL:    

-> down stairs to BROKEN BRIDGE

-> up single sided ladder -> into chamber -> along pipe -> airplane fuselage chamber 

 -> can go down into RED CHAMBER:

–> DOOR -> 

RED Path  –> somehow to red hot CAULDRON w/ control that won’t turn while stuff is in it -> manipulating it from outside turns steam on when return to top of single-sided ladder

BLUE Path -> to Blue Chamber (below)

–>  Manipulable Red Knob with view into MACHINE ROOM — moving knob moves something inside and then can’t be re-set; this seems to have turned off the CAULDRON — so now I can enter MACHINE ROOM 

-> In MACHINE ROOM is another RED KNOB, this has at least four positions.  After Cauldron boiling and Gear to RIGHT of center, can access thing that turns previously hidden switch that turns something ON (can tell by sound only)  — now returning, see into room and FAN is ON

 

 

Right on curving bridge -> elevator (initially INOPERATIVE) 

 

 

 

Right into Cave ->   (Red Path is back the way I came)

-> Blue Path

->  Ladder UP -> Another CONTROL WHEEL — Opens FLOOD GATE

 

->  Chamber toward Water Wheel control: 

->  VAULT #1 -> once Hydraulic Life solved -> ELECTRIC POWER –> solved by connecting units in order 

->

->  Once DAM is open, Stairway not blocked by water level ->  RED button allowing access to BRONZE HYDRAULIC LIFT MACHINE.

once this is UP, VAULT can be opened  

 

 

   Also this diagram that lights up when areas are powered up:

 

 

-> Door (Initially does not open; once reached from other side can open from inside)

 

 

 

 

Objects:

 

 

 

 

“submarine” door with Red handle	Cannot open originally;  I believe I later open it from the other side.
Dam	In UP position water passes the water mill
Red Wheel at top of ladder in Cave->Blue tunnel	Opens dam.  When open, gives power to Water Mill.
VAULT at Ruin	Locked
Water Mill	Apparent Power Supplier
VAULT DOOR at end of Blue cave	Locked
Bronze Hydraulic Lift	Pushes up giant hydraulic lift and then goes back down;  Apparently needs something else to be functional
Elevator	Handle just returns to its original position;  Would lift/drop elevator if activated
Handle near red wheels	Initially inoperative  — Moves Steam Controls up two more levels;
Larger Red Wheel	Turns and returns to original position; Complex, tied to other 4 wheels being correctly set
4 Red Wheels	First 3 turn one notch, the fourth will not turn;  Complex interaction;  Solved
Yellow, Blue, Red Dial	Indicator;  Moves into YELLOW when turned on cauldron and moved control to move the gear UP
Cauldron room	Lifter can be left or right;  appears to have a least 3 levels; on third level up, provides access to KNOB
Cauldron room KNOB	Turned once made accessible In this position, doesn’t seem I can turn it on from outside the cauldron room;  Looks like this must be set to the left side before I leave the room in order to turn the cauldron on again.  Now steam does come on when I twist the Large Red Wheel.

 

 

With the button pushed in the Cauldron room, we can now move up and down the lift near the 4 Red Wheels.  Steam is clearly flowing, though I can’t get the arrow to point to the red dotted line — the apparent goal — nor can I turn on the Large Red Wheel such that it stays put.  I currently have the arrow in the middle of the yellow area.  Now to check out the Elevator and the Bronze Hydraulic Lift that previously didn’t work and see if they are still inoperative.

 

Elevator: No

 

Hydraulic Lift: No

 

OK, closer look at what seems to be the STEAM DISTRIBUTOR.

I assume I’m aiming @ the dashed red line in the BLUE area.

 

On BOTTOM #4 will not move.  On TOP it is open or closed.

 

	1	2	3	4	BASE	Handle
BOTTOM	STEAM	STEAM	STEAM	Won’t move	No steam	inoperative
BOTTOM	STEAM	STEAM	CLOSED	Won’t move	STEAM	UP
BOTTOM	STEAM	CLOSED	STEAM	Won’t move	STEAM	inoperative
BOTTOM	STEAM	CLOSED	CLOSED	Won’t move	STEAM	UP
BOTTOM	CLOSED	STEAM	STEAM	Won’t move	STEAM	inoperative
BOTTOM	CLOSED	STEAM	CLOSED	Won’t move	STEAM	UP
BOTTOM	CLOSED	CLOSED	STEAM	Won’t move	STEAM	UP
BOTTOM	CLOSED	CLOSED	CLOSED	Won’t move	STEAM	UP
MIDDLE	STEAM	STEAM	STEAM	STEAM		inoperative
MIDDLE	CLOSED	STEAM	STEAM	STEAM		inoperative
MIDDLE	CLOSED	CLOSED	STEAM	STEAM
MIDDLE	CLOSED	CLOSED	CLOSED	STEAM		UP OK
MIDDLE	CLOSED	CLOSED	CLOSED	CLOSED		UP OK

If I have bottom set to, say, 7:00, and then go up and turn #1 CLOSED on TOP, it goes to 8:00 on top and remains there when I come back down.

 

TOP LEVEL: STEAM on moves dial one click CLOCKWISE.

 

MIDDLE LEVEL:  STEAM moves lever  FOUR clicks CLOCKWISE

 

BOTTOM LEVEL:  STEAM moves lever TEN clicks CLOCKWISE

 

 

AFTER SOLVING THIS.  STUCK.  Hint:

 

 

This enabled me to figure out getting the Water Power-plant Vault opened.  

 

 

Next puzzle:

 

moving clockwise from ladder  (using number system decoded in solving Riven);

assume must be solved in order

 

 

1
5
4
3
2

solving one throws the others off?  have to do them in the order of the numbers?  numbers the same as on Riven?  Yes.  I solved them in order.  Still didn’t work.  Then solved #1 again and it fired up!
