Re: Out Of Character: The Circle W Ranch ((OOC IV))
Has the player ever asked you specifically not to ghost them?
In the absence of such a request, I believe it is the GM's prerogative to ghost an absent player's character when necessary and appropriate.
If not, then I'd send a PM to let them know that their character's integral role in the story thus far somewhat begs their presence, and that unless asked otherwise informed you'll be ghosting them to keep them in the scene so they don't get left behind.
Even otherwise, to put myself in an absent player's shoes, I would rather Adrian be involved even though not under my control than sitting around somewhere, missing all the major action (which is every five minutes in Blackthorn) and then making an awkward transition back into the game where the other characters are wondering why they missed the whole shebang.
