I could totally see a decadent Vaylen community where hosts were swapped around for the LOLs: for sex, for novel perspectives on human life (hey, I’m a baby! hey, I have no legs!), for purely practical reasons.
On that note, I like that any given worm+human = a unique persona, and that is the thing you’re connected to. So that means the worm could easily wriggle out of a connection, go do its thing in some other body, but when it returned to a given host then the connection kicks back in.
A riff: maybe the connection actually multiplies…like, when the worm splits off, now there’s a connection die on the host AND on the worm. When the worm enters a new body, there’s now a connection to that Vaylen. If a different Naiven enters the original body, there’s ALSO a connection with that one. Like a psychic virus of sorts.
Mostly I’m thinking through the murder mystery goodness of the whole thing. If Worm A + Host Y kill someone, and Worm A goes off to ride around in Host Z, who’s responsible? And can the Psychologist follow – or lose – the Naiven in question?
I know there are practical, mechanical considerations in playing this out that are different than the aesthetic considerations of a mystery writer. I still think it’s cool to think about.
