Thanks for the comment I guess they are a little bit of both as the different settings involve different people but they will cross over in places and meet (possibly soon)
Each of the three riggers so far have had differing reasons to tie. The first involves an actual kidnap, the second a tradition amongst friends and the third being someone who likes to tie almost as a professional. What links them is their captives and there will be a crossover of sorts planned in a future update where the context will hopefully begin to make a lot more sense.
Hope that makes sense, thanks for reading and for your comments, they are much appreciated
