Neither Azzy nor even Leah expected this spirit of demigod would offer a trail for everyone else too.
Upon realizing that the Jewel of Earth isn't a reward for releasing the spirit remnant of the demigod, Azzy finally understood why the Reaper mentioned getting prepared for what's to come.
The Reaper was probably talking about the trial. But, then, why did he change his words and suggested stealing the jewel?
Soon, the answer came to Azzy. The probability of the future. As the deity of time and death, the Reaper could see millions of futures at the same time. Every minute action of someone leads to a different outcome. But, it isn't that all futures are completely different from each other. Most of them would overlap at one point or another.
