So I'd like to get input on a backstory, it'd be awesome if @Lawrence_Schick
could tell me if it's possible for ES lore. Made this character in similar fashion in other games and would like to see if I can adjust it to this lore.
So Kortan Vescalor is an Imperial that was once a loyal solider in the Empire's army, he values what it stands for and would go to exceptional lengths to preserve it. UNTIL the events of ESO and discovering that the Empire is pretty much ran by the Worm Cult and most of his family takes part in Daedric rituals. He defects but only to one day march back into the city and his family in hopes of freeing it from Daedric influence. Seeking guidance and the blessing from Akatosh, who he truly worships, he leads a neutral faction of anyone from mercenaries, mages, and misfits who'd join his fight to free the Empire from Daedra. He distinctly hates all forms of Daedra with a slight tolerance with the "good Daedra".Here's where I'm not sure if this is not lore appropriate.
What he does not know, or what he soon discover, is that his father (who may be working for another Daedric Prince that isn't Molag Bol) had attempted to preform a ritual on Kortan to exchange his soul and conjure a powerful Dremora from banishment to process the body. The ritual was interrupted and something went wrong, Kortan now shares his body and a part of his soul with a different Dremora that seeks revenge on the Prince he was intended to serve and has an agenda of his own to fulfill. He would help Kortan but one day would wish to purge the host out of his body so this Dremora could be free. Having the Dremora within him gives Kortan access to tap into some powerful abilities and magic he never thought possible to bolster his own skills, but at the cost of his own sanity. At times a trigger could occur and the Dremora in him would gain control to do as he wishes for a period of time. What stops Kortan from finding a ritual to reverse the affects is the potential power it gives him and would use to aid him in his fight. But is it worth the price?
