The life-and-death duel proposed by the Sand Tribe Wizard is officially known as the "Heavenly Mandate Life-and-Death Duel."
This is a very ancient tradition among the Sand People.
The Sand Tribe, entrenched in the Western Region Great Desert, has never been truly unified; the major tribes occupy different oases, forming a situation of regional hegemony.
On the surface, these tribes all submit to the Hidden Gold Palace of Sabak City, but in reality, they obey commands but not proclamations.
While different tribes form alliances with each other, wars often break out over resources.
Countless Sand People have stained the yellow sands with their blood.
Hatred is something that can be inherited and continued unless one side is completely wiped out. Otherwise, it's like aged spirits, the longer it's stored, the more concentrated it gets, until it is impossible to dissipate.
The brutal wars between the tribes have caused continuous bloodshed among the Sand People.
