So I'm at the place where I know I'm meant to use it, after all of the dwarven stuff. I've used the cube thing on the right side of the console, but it won't let me place the sphere. Could anyone give me any help? I can't continue without getting the Elder Scroll down.
You have to fiddle with the two you have access to until the third one becomes active, then fiddle with that until the fourth one does. As I recall, I had to press the second one three or four times before the third opened. --- FACT: Four out of five people are crushed to death by giant diamonds every day.
