Maybe we could use a thread to post queries on how to get to specific areas, ideally posting an image of the node in question and images on where it is in response or at least detailed information on where a door or entrance is to that node or sub-node etc. I have one of course, everything we do is done out of self interest right?

You have to lower the water level to get to that sub-node. That all comes later. Or earlier, Fez is unhelpfully non-linear.

@Gatehouse: How exactly do I lower the water level? Is there a valve in that region? Or on that particular area itself?

@DJJoeJoe: It's actually quite close, the lateness of me finding it threw me off. It's a secret room hinden behind the waterfall of the stage next to the first warp zone (hope that makes sense). It's the level where the waterfall looks like it's crying. You have to part the waterfall with the crazy tetris code on the pillar, which you find up in a lost city. Or, at this forum here....
