I have an antihero Orc character. The idea is he's a dark character ultimately working toward the greater good. Think Deadpool, Wolverine, Kratos, or lethal protector Venom. I was thinking of doing the civil war questline but I don't know how to approach the quest. He has a disdain for the law since it didn't stop the black-briars from murdering his family and torching his house. Plus they were gonna behead him without as much as a trial. However Ulfric doesn't seem fit to rule either because of his narrow minded viewpoint. So what would be a good option here or should I skip it altogether. Is there any other guilds I should work with along with the companions?
so to start off you should not even talk to bryjolf thieves guild quest line and kill the dark brother hood and go anti hero until you find out you need to kill dragons for the good and then go hero. Go with who you want to be the hero of skyrim (stormcloaks) or all of tamrial (imperials) the companions don't work with any other guild.
