Cross Regia, Chronicles of the Twin Worlds: "The Traces Left Behind"

The city, once a shadow of its former self, had been reduced to rubble by the disaster. Collapsed buildings. Burnt steel beams. Countless rubble covering the ground. In the silence, a man walked. Looking around as if searching for something, the man slowly advanced. And then— "…………" The man stopped. A faint blue light leaked from the gaps in the rubble. He knelt down and carefully moved the rubble aside. Buried beneath it was a small, blackened, charred fragment. The man picked it up. A pale blue light, like a crack, ran across its surface, and it continued to emit a faint glow. Clearly, something that shouldn't be here. And the man—he knew what it meant. "...As I thought, here too..." He murmured softly, his gaze fixed on the fragment. It wasn't a coincidence. Something was at work in the shadow of this disaster. Who? For what purpose? And—how far had it progressed? The man clutched the fragment and quietly stood up. Behind him, a “presence” unknown to people yet stood silently. A single fragment discovered that day in the ruins. What was it made for? And what is it trying to bring to this world...?
