Gonna be a slightly heartless GM here for a sec in an effort to preserve the RP: Eisenhorn has at least been on the guild, and has been posting sporadically, so this leads me to believe he's simply not choosing to post here.
If he posts that's cool, I'm not kicking him out or anything, but from now on we don't wait for him and unless he's interacting with us/ posting we don't have to go out of our way to acknowledge him because it just slows down the plot and creates holes.
