I'm not one to post often, but I just feel the need to say I have faith that Paizo will continue to mold their world in unique and interesting ways that don't have to be connected to what WotC have already done. I liked drow, like someone who posted before a drow was among one of my first characters, but over the years I fell out of love with them and honestly I'm fine with seeing them go, and I'm excited to see what the serpentfolk might feel like in their place as the most dominant species underground.
