Born in an unnamed place at the outskirts of Zemuria, Wazy grew up in a village in which contact with the outside world was prohibited and where an ancient deity other than Aidios was worshiped. As a child, Wazy served the village as a medium able to hear the voice of the local deity.
One day, villagers one after the other fell into a deep torpor for no explicable reason. Upon investigation, Wazy found that the local deity was rampaging and absorbing the energy flowing through the earth veins. Rather than taking his suggestion to seal the veins into consideration, the village elders began discussing a human sacrifice to appease the deity.
At that moment, Gralsritter from the Septian Church arrived, which led Wazy to realize that the local deity was not a god but in fact a slab-like artifact. Wazy tried to destroy the artifact by throwing it off a cliff to release the village from the ancient spell the artifact had cast on it. The artifact resisted this attempt and overpowered Wazy, which led his Stigma to awaken in self-defense. His Stigma in turn absorbed the artifact's power, turning it into an ordinary lithograph that crumbled away in his hands. Wazy was then banished from the village, accused of murdering the local deity.
The Gralsritter escorted the now-exiled Wazy to Arteria where he was then welcomed as one of the twelve Dominion.
