To continue with the roleplaying I've decided in the spirit of Nordic victory and superiority to butcher every non-Nordic character in Skyrim like as part of Ulfric personal stormtroopers or death squad. Targeting especially all Imperials and beast races especially. I'm on a PC so I can make essential NPCs non-essential. I feel this is the ultimate way to make Skyrim for the Nords.
My question is, is this really possible? Do foresworn and other non-Nordics respawn at various dens? I want to walk around Skyrim eventually without seeing any non-Nordics except for animals which I can't do anything about. Also would this ruin several quests if I kill characters before I complete them?
I feel this is the natural next step after Ulfric's victory but obvious this is non-PC so there won't be quests like this put into the game so I'm just roleplaying as Ulfric's SS and having fun with it.
Any thoughts or suggestions would be appreciated.
