Seven for a Secret, Never to be Told

I think it's hard to say anything definitive this early into season 2 and based on only the brief mention in this first episode, but I definitely have some theories.

Ruthie's girlfriend has to be some sort of divine entity, She just hasn't interacted with the material plane directly enough, even before she fell, So of course the obvious answer is Rua, but Wiley and Glow have shown that Rua and Ruthie have never had that sort of relationship, so that means it's another god.

Of the rest of the Mesavan pantheon, I think the most likely answer is Nyssa, It sounds kinda random but think about it, why would Ruthie land in Thrallia in s1e1? Rua wouldn't send them there, Rua would send them to the mainland where they could become the devil Lazaruth. But Nyssa had a shelter, a place where she could send her girlfriend to make sure she had the chance to recover.

I think that's also probably why the cult of Rua attacked Thrallia first, Rua wanted to punish Nyssa for helping her girlfriend and also then use the destruction and blame it on Lazaruth.

I'd actually argue the opposite! Mesava is an extremely theocratic society, no debate there, but I think that's exactly why they can get away with so much, like short of the Divine of Rua themself house aeroth is arguably the most significant and powerful religious institution on the continent.

Rua is the head of the Pantheon, their primary aspect is balance, but they're also the god of judgement, duty, all those sorts of things you'd expect from the leader of the gods
