Strange glowing spells? When I wonder. I saw a dialog path where you discuss some strange magic with her and ask her whether it is Shar magic. But I don't remember when that magic actually happened.
She will start glowing as you finedshar/selune ruins
Regarding "Lathander's Light"
I'm pretty sure the githyanki creche will be situated in an abandoned temple to Lanthander. That's probably where she got the buff, I don't think it's related to her character. You can see what's likely the temple in the recent teaser trailer
Here. There are other glimpses of inside the temple from previous trailers this year but I'm too lazy too go find them.
Its a temple of Lethander sure, but why would the buff be active on her like that if it was some sort of quest reward? I believe swen even said his party went through the underdark so they would have missed that temple entirely right?
