Do you actually have a plan for the dark continent though? I have not caught up with the manga but I assume that since the place is too dangerous it just leads to 'seeing whats up there' and that just sounds like a rp that ends up being more and more monster of the week type roleplay. If I'm mistaken feel free to correct me but I feel it'd be a whole lot of just 'wow this place is neat' instead of 'I wonder what we need to do to stop the corrupt hunters', 'zoldyck assassin is trying to kill our friend', 'weird science experiment from some sort of mad man' or 'chimera ants attack' that you'd get in the setting from the main areas.
