Skyrim, follows the adventures of the Dragonborn. It'd be ambiguous to if he'd chosen to side with the Empire or the Stormcloaks and certain quests and factions like the College of Winterhold quests, Thieves Guild quests, and bigger questlines would get at least 2 episodes, while miscellaneous stuff like follower quests, bounties, word of power hunting, etc.. would most likely be the starting framework for an episode. Like, Dragonborn just finishes a followers quest to retrieve a Moon amulet from some bandits, on his way back to wherever, he could hear a Guard talk about tie Dawngaurd or something, which would then see him off to their fort near Riften.
