In the ominous melody, the strange petrified musician waved his hand. The earth shook, and cracks formed striations on stone and iron, making them seem as if they were covered in frost. Ruptures sounded one after another.
As the paving bricks on the ground cracked, iron fences rose from the rotting soil, layer by layer. Decaying metal wound around the fences, turning into a forbidding barrier, like creeper plants which were spreading their vines and leaves meticulously.
On the dark green metal leaves covered with rust, layers of notes emerged, forming a huge and complex movement. In the blink of an eye, access from all directions had been blocked, turning the place into a cage that would allow no one to leave or enter. It was a shackle that sufficed to hold even a gigantic Phantom Beast in it.
