Shard, still feeling dizzy, stared blankly at the strange spiritual light. It wasn't the Spirit Rune itself that surprised him, but he vaguely understood something:
"Whisper - End... Whisper Element, it can only appear on Relics or related powers. But right now I haven't touched any Relic other than the Black Time Key, and that key is not the source of this Spirit Rune. The Spirit Rune comes from the world of this Space-Time. Whisper... Whisper... does the Relic and Whisper Element really represent the 'Darkness of the World' that Dr. Schneider told me about (Chapter 14)?"
He took a deep breath of the choking air and recalled another description the doctor initially gave about the "Whisper Element" — "Whisper is almost a natural phenomenon, resonating throughout the entire Material World."
