After collecting the items from the Scourges of the Devil headquarters, Minos distributed a portion of them to the Snow Kingdom forces.
But this had not been anything significant to those people, only having been a consolation prize, or rather a 'medal' to the meritorious service they had participated in.
In addition to 25 million low-grade crystals, Minos gave King Snow all grade-1 items, as he was no longer interested in artifacts of that rank.
Grade-1 artifacts might even be helpful to the growing population of the Black Plain. Still, they would make little difference in the big picture. On the other hand, even though he was the regional leader and owed nothing to anyone, it was not good for him to give absolutely nothing to those people.
At the very least, their work needed to be recognized to some degree, even if many of them had participated in the previous battle of their own volition.
