The Elder Scrolls VI

[Winter]

I bet you will be frozen in time by a Daedric prince, and when you wake up you must search for your son.  You eventually find that he has become the leader of the evil shape-shifting cultists that you thought kidnapped him and that he has aged into an old man, and must come to terms with either killing your son for the greater good or siding with him and helping his cult rule the land.
