[Theory] Quruitzia and Eris (Jure's sister) - Spoiler included

[Dracon]

Just want to throw this out:
Jure (The Goddess) has a sister of whom she only knows that she exists and that she should have memories about her. - The other gods refuse to answer to her on that rewgard.

We have no idea what kind of goddess Eris is, but given that no one comments on it, it is safe to assume that she might be a traitor or chaos goddess.

Quruitzia has a dangerous and rather devastating power hidden inside her eye, and also partially lacks her memories. (the spoiler part)

Assuming they didn't just overuse the amnesia theme:

My theory is thus that Quruitzia either is Eris herself, or has Eris locked inside her ill eye. It should be said that having some kind of monster/dark power (usually a dragon) locked inside your eye or arm is nothing strange in anime. - Nor is the delusion of that being the case for that matter. (8th grader syndrome anyone?)

And no, I will not spoiler tag it, you were warned in the title.
