Hi there. Thanks for being so respectful. You can read a lot more about my beliefs and experiences on my webpage: http://fictionkin.net/
To answer your questions shortly: I have met people who were kin of Pearl, and people who were kin of Vriska. I have never met another kin of the Kaizer, and I have never met someone who was kin of all three. Normally we don’t talk to one another much- in general I don’t get along with other Vriskas, but I’ve had some positive interactions with other Pearls, which I guess doesn’t surprise me.
I don’t believe anyone to be the ‘one true’ whoever; I believe there is room for many of us due to believing in multiverse theory, which you can read more about here: fictionkin.net/multiverse-theory/
Thank you for the kind words 🙂
