I have no idea, actually. It's not tied to the Randomizer -- we've shut that down twice now, and the Voices predate it. We know the hosts are all about to start some big journey when they're chosen, and when they're guided, they come across problems to fix in their region and usually become successful along the way. It's even possible for someone to call the Voices to themselves when they're about to choose someone else, and sometimes the Voices wanted a different host than what they got, so even they don't know what they're doing all the time.
