Been playing Skyrim again lately, I abandoned the Dawnguard, became a Vampire Lord, and returned to my dark brothers and sisters in Dawnstar to laugh about how I used the Dawnguard to slaughter Harkon and his clan, freed his daughter, and took his castle for shits & giggles.
Now if only I could make the rest of my story happen, you know... Where I manipulate the remainders of the Stormcloak Army into killing Brunwulf so I could become Jarl of Windhelm, then manipulate the Empire into tracking down and catching those Stormcloaks and bringing them to Windhelm to use as a free "work for your freedom" prisoner workforce to repair the city, the
Gray Snow Quarter, and rebuild The Pit. Of course, none of them would live to be freed, I'm with the Dark Brotherhood, remember? One-by-one, they'll start having 'accidents' or simply show up dead. Oh, I'd also give equal rights to Dunmer, Khajiit, and Argonians, on top of allowing the latter two races inside the city walls, just to piss off the Nords there.
