With that in mind, I'm going to recommend that we hold off on any further action until this weekend. If Z is still not around by then, then I would support
@TheWarCaptain taking over if he is up to it. (And if you are then take these few days to flesh out some form of story, which I would be willing to help you with for the most part.)
I would take the reigns myself, but I have my own RP that is woefully overdue for an update of its own (its coming everyone, theres just only so much free time between sixteen hour work days and sleep when your working six of seven days. Writing posts, let alone updates, on a smart phone is a far cry from easy.)
