[Skyrim] Where will I go when I die? I've heard mages of great renown say my soul will go to Father-Akatosh wen I die... but Mora takin Miraak's soul for himself has made me wary. In the foolishness of my youth I may also have made a great many pacts with daedra.

The last dragonborn's soul is that of a dragon, which means it's part of Akatosh. Ultimately, that's where it will go, even if it takes a while to get there.  

Herma Mora did not take Miraak's soul, but unnaturally extended his mortal life by confining him to a realm of Oblivion. In fact, when Miraak finally dies at the hands of the Last Dragonborn, his dragon soul is absorbed by said dragonborn. 

There is a very good chance, depending on the decisions the Last Dragonborn made, that they will be allowed to rest in Sovngarde for a long time. Perhaps a fraction of an eternity. All the while defended by the heroes and souls of the dead who the Dragonborn saved from Alduin. No daedra has a permanent, binding claim.
