This would be a Supernatural group PSL, pulling in a mishmash of elements from medieval, the old west and whatever else little boys like to pretend play. Both canon and original characters would definitively be welcome, but in the case of the former, they would have to be reconstituted to fit Jesse's imaginary world.
Tell us what you want! Premades, yes or no? Mishmash of settings or stick to one (e.g. strictly medieval or strictly wild west, whatever)? Y/N to angels and demons? Something else you had in mind? We could also use one or two additional co-administrators to bounce ideas off of. :D
