Does she react at all to Ellisaria's entrance to the church?

Not visibly.

Initiating interactions. How tiresome.

She walks over to the sitting priest. "Hello."

The priest looks somewhat annoyed about being interrupted. "Can I help you?"

"I am looking to learn more about the god Tyrion. Are you who I should be talking to?"

"I'm not a completely incorrect choice, no."

"Would you prefer I returned at a later time?"

"Well, you've already interrupted me, you may as well continue." She gestures for her to sit on the floor.

She does so, imitating the priest's posture.

"Shall I ask all my questions at once, or one at a time?"

"One at a time would be better, as to avoid asking questions that would answer themselves."

"Your god has a brother, yes? What is the relationship between them?"

"They are twins, born in the World-that-was. They awoke together in this realm, after the reformation of the world, but Tyrion had been blinded. He and Teclis explored this new world together, with Teclis being the eyes for both of them."

"And was what they saw much different from what I have seen today?"

"Less settled. No aelves had been found then."

"How did the gods come to find the aelves?"

"There were some in Azyr, but the rest of us were rescued from Slaanesh."

"And for that you give these gods your worship?" It is entirely unclear whether she thinks that's good or bad.

"Not purely for that-- but that is an important part of it, yes."

"And what do the gods get from it?"

"Allies. Power. The ability to bring huge amounts of man-hours to bear."

"What are the tenets of your religion?"

"To defend those weaker than ourselves. To strengthen ourselves, so there are more who we can protect."

"Is that all?"

She frowns. "Of course there's more. If you want a novel I can give it to you, but I doubt you want that."

"Perhaps. What happened to Tyrion?"
