You don’t have to do a post a day! I’d say once a week is fine. Suitable length....multiple paragraphs? You can check out my other active RP “In Dark Seas We Sail” to get an idea of what I usually write. I expect my partners to be able to match me but not necessarily all the time. If you can give me something meaty in two solid paragraphs, that’s fine. I’m not draconian about post frequency or length, I just expect substance. What do you mean biomes? Because I picture a bio dome LOL. Probably not what you’re thinking haha. I’m not familiar with Arabian knights but Azurei culture lands somewhere between Arabic and Maori cultures, if you can picture that, so you’re on to something.
