I'm guessing that you toggle the levers in a pattern to activate it
I've been wanting to do that too
The lever puzzle is the only part I cannot do....all of my guildies can do it super fast but I always get it wrong!
But yes...first step is the lever puzzle...you have to figure out the pattern to unlock the door to spin the time machine.
The door is just West of the levers
Once you figure out the levers, go through the door and spin the time machine to break down the rock wall
Beyond the wall is another puzzle....figure out which tiles to walk on that won't zap you! While avoiding the big blobs!
We use gold or some piece of food to mark which tiles are safe to walk on!
Then you spend like 800k gold to get the power cores to activate the machines...only one power core is needed for each machine..once they are activated, a portal will appear to the North leading to the city center.
