All attempts to interact with the floating mural seems futile.

The image seems to show a decaying image. First a grand castle of unknown location or origin. Gradually, the image goes from a calming blue glow to a dreary grey one. The castle becomes windswept and decays, stone walls eroded to merely piles of rock, and what was a beautiful courtyard has devolved into a quite barren swamp.

The waters, murky and filled with muck, bubbles slightly.
