cap would suck for Acacia until there is an RP escape item to survive the dialog. So I think if an escape item is created that character can develop over time. In fact, using an escape instead of an Allure can be a moral victory as well for anyone interested in that.
I don’t mind your RP storyline idea, but all storylines feel kinda meaningless to me in the hypothetical. My Gareth doesn’t have a sister, so I don’t have a bias leaning towards “What if he did”. My villagers can’t even entirely settle on their own backstories, so I’m not committed to cementing any one story yet.
I like your ideas though, and I share the desire for their to be more point to Acacia than there is now. Fingers crossed, moral support for TD and all that.
