I know Blood and Wine is supposed to be the very final story for the series but I would just love it if they had just one more story pack involving Geralt's parents. I honestly wish that they would explore on Geralt's family in Witcher 3. I was thinking for my story idea that Geralt would recieve news involving his family and they are in danger so he must go out to help them. Like Blood and Wine, there could be a few different endings. A bad ending could be that his family dies and he's left feeling forever guilty for failing them. A good ending could be that he saves them and he either leaves them promising to always be willing to help them or they could move in the land where Geralt got his house in Blood and Wine and they would be forever close to him. Another add in to either ending is that I was thinking due to a powerful, unknown to most spell, Geralt has been granted the ability to produce just one child so assuming he's with either Triss or Yen, he would be able to impregnant them and they would have a child together.
