If the messages in my PM folder are any indication, more people are interested in a slave RP than you realize. But most of the people who PM me are looking purely for 1x1 smut (not all), and that's fine, but I also wanted a group thread with a focus on story. The beginning of the tale where the characters live in Rothenburg would offer part of the slave RP aspects some people are looking for, but as stated in the intro post, the focus would shift to them as refugees fleeing the civil war. There's not much room for a "rape fantasy" when you're fleeing or fighting for your lives to get across a border. 

Anyway, it doesn't really matter because I no longer intend to cultivate this particular RP. I have enough people wanting to do 1x1's with this type of setting now that trying to move forward with a group RP on top of that would seem repetitive to me.
