User blog comment:Bacon is Good/War over Dragonborn/@comment-1992639-20120605220340

People will probably look up to the Dragonborn, so I expect him or her to pull a Tiber Septim and start a new Imperial dynasty when the Thalmor finally go all-out. So maybe they'll pull a Talos and become a god, or their Dovah soul becomes a dragon in some way. Supposedly dragonsouls are immortal. I imagine upon the Dragonborns death, those absorbed souls are released again.

But remember that regardless their race, Tsun promised to see the Dragonborn again in Sovngarde when he or she dies, so that sounds pretty solid to me concerning where the Dragonborn goes in their afterlife.
