Weis have already confirmed that Season 5 will have a storyline on Dorne in the aftermath of Oberyn's death.
The Dorne storyline will include an arc covering the feared 'Sand Snake Sisters,' Oberyn's illegitimate daughters who will be plotting revenge for their father's death. Playing the 'Sand Snake Sisters' are Keish Castle-Hughes as 'Obara Sands,' Jessica Henwick as 'Nymeria Sands,' and Rosabell Laurenti Sellers as 'Tyene Sands.'
