I was racing across the shores of the Sea of Ghosts from Dawnstar to Winterhold. I needed to get there in a hurry before I froze to death (Frostfall). Halfway between Saarthal and Winderhold, I encountered a group of Imperials and Stormcloaks battling. My character being a Paladin type, and an Imperial himself, decided to use Voice of the Emperor to stop everyone fighting. Played it off like he broke up the fight and saved up to six lives of his fellow man while he was on the verge of death himself.
It was an interesting roleplay opportunity. Normally, I let the flight play out, as most of the characters I've played have no real dog in the fight. Any other time that's been pro Imperial or Stormcloak jumped into the fray for his side. Never had the chance to think outside the box, but it felt right for this character.
