Twintails lies at the bottom of the pool and thinks for a little while.
She… supposes it actually could be possible to be Unveiled but not know about magic. For instance, if you were Unveiled but then you lost all your memories, including your memories that magic is real. Would the gods decide that person is Veiled again, or would they still count as Unveiled? She's not sure. But she's heard that some gods steal their clerics' memories sometimes. Maybe some of the time they go around not knowing about magic.
And actually… she's also heard of people who can do enough magic to count as Unveiled, but they haven't discovered their magic.
And she's also heard of mythic creatures where you could be one and not know it, if nobody told you. And those all count as Unveiled.
She doubts all these people are one of those, but… it means it's not literally impossible that they're Unveiled but don't know about magic. Which means maybe she wasn't lied to.
That's all she really needs.
