As the title suggests, how do you see your character developing post-game? Does your Dragonborn settle down into mundane city life? Do they go into politics (In Skyrim or Cyrodiil)? Do they carry on adventuring/dragon hunting/leading the mercenary life? Something more mundane or grander?

As for my character, he ended up filthy rich and high up within the legion. I could see him usurping Tulluis for control of the Skyrim legion. With it under his firm control, and it filled with legionnaires unhappy with the state of the empire, he would have marched south for the Imperial province. With the legion as the main fighting body, it would be reinforced by my characters personal army of huscarls and supported by the reforming blades (aiming for revenge and to retake their position within Tamerial society). With so much gold amassed, a sizeable contingent of mercenaries could have also been recruited and any of the flocking plebs, coming to the Dragonborn's banner, could be armed. Not to mention being Thane of all of Skyrim's holds, and having done extensive favors around all of them, am sure some would send some men to help.

The Empire would be, assuming all quests of the game had been completed, looking for a strong leader. I don't think anyone would oppose (that much) the rise of a new Dragonborn Emperor.

Eh, I just roam Skyrim. Wherever the roads take me.

My Dragonborn's story is still being written, but ultimately I think it would be nice if he and Lydia settled down somewhere with the occasional adventure or two.

Achievement hunting, at this point. Doing the Daedric quests, building Hearthfire Houses, rampaging through bandit camps in Werewolf form.

He walked off into the wild never to be seen again.

The none ending quests, example: Dark Brotherhood, Thieves guild, Dawnguard, Vampires, etc etc. Or I just start a new character. If they had an option to start a character completely over story wise and keep all the lvl and perks you have. Simply just start all the quests over, I would do that.
