I may or may not be brewing on the possibility of the Martell Cartel if permitted to do so and the Vegas/Mafia plotline comes to pass. The primary point of view would no doubt be Oberyn. I'm not quite sure how I'll tie in people like the Yronwoods and other Dornish nobles yet, but I've got a basic outline to set up a healthy Martell-Lanister feud assuming the Targaryens were a thing at some point and we crafted the story to sort of mirror the events of Robert's Rebellion and other such things leading up to the first book/the RP.

I should say I've read the novels and would be introducing characters not yet seen by the TV crowd, namely Doran, Arianne, and the Sand Snakes, just a heads up in case anyone wanted to involve the Snakes of Sunspear.
