I wonder if Kiedran living around some magic makes their eyes blue. Looking back Natani's mom had blue and green eyes. The Riftwalls both have very blue eyes.
Maybe they are just more sensitive to magic. 🤔

I dunno why. But I feel like Vanity is going to stick around Keiren because she has a twisted sense of "You caught me now I am yours."
And I could see funny interactions of her calling herself his slave and him saying she isn't.
