After running away from Berk upon discovering the truth about dragons, about how this hundred year war was for NOTHING, you simply reflected on how your village and even your father, chief Stoick. However, upon beating the Red Death after learning the truth about dragons, you had heard your father was killed trying to find you. You were told you were not one of Berk, the reason why they need a new chief... To leave. But you didn't.
Instead, you stayed, promising to gain Berk's respect one way or another. You HAD ruled Berk with an iron fist... but with the best intentions, melding the Vikings and dragons into one nation. There were some who liked the old ways better, but you took care of them. Luckily, one of the people who embraced this change was Astrid, a girl you were attracted to, was at first following you to see how you got so good at dragon training as SHE was suspicious and jealous of your skills, but upon taking her in a flight... Her mind was changed too. She soon become your sergeant of arms, then your second in command... And finally, your wife and Berk's new empress.
As of now, you overlooked the massive empire of Berk from your perch, a large house sat atop a tall peak overlooking the town with your dragon by your side. From behind, Astrid comes up, wrapping her arms around you with a smile.
And just how is my fine emperor today?
