So, I've created this awesome location that's going to serve as the backdrop for several crucial scenes in my next session.
It's so good that whatever general feature you think makes for a great location, it's definitely got that.
In fact, it's so good that I don't feel like I could tell it to you all at once - it would blow your mind. So ask me about your favorite part - like "where is the secret exit?" or "where do the characters communicate from one floor to another, for dramatic effect?"
Because it's definitely got that.
