Like say, after the time wound it has been several months passed due to unforeseen issues, the dragons have taken advantage of our untimely absence and have taken several holds.
As we choose a side in the civil war, the dragons scramble to take the holds we do not favor, prolonging the war and converting those holds to dragon worship/control. The Jarls are deposed, and several holds are ruled by named dragons..preying on the insecurities and desperation of the opposing side.
As we move through the altered civil war, we eventually have that peace summit with the same people as normal, only towards the end there is impasse due to the control of the dragons. Alduin appears and calls us out to battle and we fight him alongside Paarthurnax, Ulfric, Tullius, and the blades (which gives an explanation for how they even figure out the Greybeard leader is a dragon)
As we defeat him there, the dragons become more independent and unsure. We then confront Odahviing who is assaulting Whiterun with an army of other dragons and Draugr etc
Also, both Alduin fights are 100% scrapped and redone from the ground up to actually be unique and challenging.
