Ivita understood that the so-called Feast Ritual was a means for witches to share power from the demon god of Subspace.
This was probably the reason why a city-state like Epirus could have so many witches residing here and even establish a hierarchical Witch Council.
In Epirus, at some unknown time, near the hills behind the city, a demon god appeared, blurring the boundaries between the material plane and the Subspace Plane. However, it seemed the demon god was sealed here as well.
After discovering this, the witches stayed here, using it as their base.
This could explain why the witches of Epirus were much stronger in magical power than witches from other regions.
A voice emerged in Ivita's mind.
'Honored guest, you have come from afar, and we've been remiss in our welcome. Please wait until our ritual concludes, and you may share in the demon god's power with us. Here, this power is of the least value.'
