While Herad used the Forge of Souls spell to improve Ulthalesh, he also added some weak souls to tinker with.
It was much like adding sugar, sesame seeds, and other ingredients while kneading dough.
Devouring souls could cause tremendous harm.
Those powerful soul practitioners who called themselves Masters of a Thousand Souls devoured souls indiscriminately, swelling their soul bodies until they were enormous and powerful.
On the surface, they seemed quite impressive.
