As for me my dragonborn spend sometime with his family (mjoll,boy and a girl) in their handmade house by the dragonborn just by the lake (hearthfire dlc) and after that he trains with the greybeards for a time before departing to solstheim to check progress and status there and then traveling to morrowind to help the dark elfs and to explore and seek knowledge about the neveraine wherebouts while still keeping in his mind about the thalmor threat and finding a way to keep the empire together and make it stronger again after sadly doing war with their brothers the stormcloaks.
