WARNING: LONG READ. PLEASE BEAR WITH ME. I PROMISE YOU IT WILL BE WORTH IT!!!
After completing the main story, did you ever get that feeling that not much changed after you defeated Alduin? I was expecting a huge mob o people running to me and praising me as the killer of the World-Eater. And I was expecting more of the conflict between the dragons and the Blades. Sure you get to kill Paarthurnax (which I did not do) and go on dragon hunts but I wanted more from the dragons' side. Paarthurnax did say he was teaching dragons the Way of the Voice (you can see a friendly dragon flying around the Throat of the World after beating the main quest) and it'd be cool to have a story driven questline with the dragons.
Let's cut to the chase. Here's what I'm proposing:
*The choice you made in killing Paarthunax or not will affect your role in the DLC*
If you killed Paarthunax and joined the Blades, then you continue on your quest exterminating the dragons in addition to recruiting even more Blades (maybe 20+) and establishing more Blades temples. It's be awesome if there was an epic battle with 5+ dragons and dozens of Blades, maybe during a dragon raid against Sky Haven Temple or any of the other Blades temples. When word goes out of the Blades' success and existence, the Thalmor crackdown and wage a small war against the Blades. In an instant the conflict turns into a 3-sided war between the Blades, dragons, and Thalmor. Once you defeat the Thalmor and killed all dragons in Skyrim, the story is set for another DLC where you venture to Akavir, the home of the dragons and where Alduin has also risen more dragons before, and kill all the dragons there (and there will be quests related to the denizens of Akavir).
If you did not kill Paarthunax, you still have a choice of killing him and joining the Blades or siding with the dragons. At first Paarthunax will call for you and he will ask you to choose sides. If you side with the dragons he will ask you to defeat multiple dragons and convince them to learn the Way of the Voice. Once completing that task you return to the Throat of the World where several other dragons, along with the ones you convinced and Odaviing, are congregated around Paarthunax. Here Paarthunax talks about the dragon killings by the Blades and because of the Way of the Voice, he commands that they do not fight back. Several dragons fly away, pretty much saying "this is BS." Paarthunax asks you to talk to Delphine and Esbern and convince them that Paarthunax has converted many dragons to the Way of the Voice and counting. After talking to Delphine and Esbern, they are not swayed and banish you from Sky Haven Temple. After telling the news to Paarthunax, he finally understands that the Blades will stop at nothing and he launches an attack against Sky Haven Temple. He offers you to ride his back and you decimate Sky Haven Temple along with other temples. The Thalmor intervene. Now you get to kill Thalmor and Blades. After defeating them the story is set for the Akavir DLC where you go to convert more dragons to the Way of the Voice.
I know it was a long read, but I hope it was worth it. Thank You!
