The Whispering Hall
Envy then asked Thomas the question Daniel had instructed her to ask. But the soul suddenly stopped cooperating and began to crack, disintegrating without a trace. It was as if someone or something had triggered a failsafe protocol within a machine.
Daniel used this method in artifacts he built himself, and some of the high-end artifacts from his workshop employed this failsafe to prevent them from falling into the wrong hands. It seemed the same thing had happened here. The moment Envy asked about the dimensional coordinates, the soul self-destructed.
Everyone in the meeting room understood what had just happened. The soul had self-destructed the moment it was asked about the dimensional coordinates. Either a connection to the main body remained, or a failsafe mechanism had been embedded within the soul.
