Would it be possible to have a mod for the "King's Gambit" quest in Skellige where I would be able help both Cerys AND Hjalmar in any order in what they're doing and then get a pop-up/menu where I can just decide who becomes the ruler? Cerys is my default choice but I also want to be able to include the fight with Hjalmar where we face the Berserkers and uncover their cult even if I think Cerys is the better option. Also would it be possible to make this mod Next-Gen compatible?
