Black Plain in Rebellion 1

After the assassination of the leading members of that group sent to the Black Plain to negotiate with Minos, the royal family had found out about it almost immediately.

Some of those individuals at the 5th stage and all the Spiritual Kings in that group had soul lamps in the royal family's headquarters.

Consequently, their deaths had not gone unnoticed, and the Brown family had immediately understood that there was something wrong in the Black Plain.

But just because the soul lamps had indicated the deaths of those people, it gave them no clue as to what had caused such an incident.

Could it be the forces in Dry City?

Could it have been some other regional royal family?

Perhaps some organization outside the northern region of the Central Continent? 

They couldn't be sure of any of this.
