yes, I have gotten through the four towers. But there are a total of five towers that you must go through. Must retrieve five orbs. Frozen tower Electrical tower Windswept tower Molten tower & Ashden tower I can't find the access to the Ashden tower through the castle. Thanks,
Never mind gang. I found it. I was walking right past it. There are three entrances on the left and two on the right. It's the middle entrance on the left. my bad.
