Any one universe has endless different timestreams, because every decision has an impact, every influence will create something new, but outside of that, there are endless other places. Places where you and I and Night Vale have never existed, and places where we exist solely in fiction. I've heard your voice come out of the mouth of an actor, I've seen my exploits printed and sold in bookstores.

Finding the right one is like finding a needle in a haystack, as the saying goes, but it's not impossible. Least of all for me.
