Having played a character that was loathed by a majority of a clan simply for being my clan. Having to play through it and over it to get information on things and work out with the few that didn’t hate me but watched them get it instead and sometimes purposefully to lessen my own hate, it is a strange but good thing.
No good story is complete without adversity. Just because they are a rival doesn’t mean you can’t be dealing with them. Think of GoT and similar stories, sometimes your worst enemies make your best allies until they then turn as well.
