"Astrid! Make Stormfly give it back! I actually need it!" Hiccup hollers to his girlfriend Astrid. Her dragon has stolen his map of the surrounding lands. Normally a fun game, but not today. He needs it to make his point in a meeting of clans this afternoon.

"Fine, fine. Whatever. But you owe me dinner tonight!" she responds with mock frustration. He smiles at the dinner part. Tonight is the night that he has chosen to propose to her. A midnight ride after dinner will be a splendid opportunity.

"How about 8? Will that appease your highness?" he jokes. She smiles and agrees. He grabs the map and turns Toothless back toward main hall.

Ever since the death of his father, Chief Stoic, Hiccup has been going through his father's things. Chiefly things, like old papers and trade agreements. What he found and what he chose to do about it would change history. But back to what I was saying.

Before Berk solved its dragon problem, they had had allies and enemies. The problem was that when the dragons came, they couldn't ever attack their enemies or help their allies, so eventually all that remained was the hatred or companionship Berk felt toward these kingdoms and villages.

Today, Hiccup is making the first step toward reuniting with their allies to destroy their enemies.

Mainly, a pesky little kingdom called Arendelle.

Berkians hate Arendelle. Why? Who knows. But they do. So he is going to, with the help of their dragons and their allies, wipe out Arendelle. It is totally out of character for him, but he feels like it is what his father would have done, so he is determined to do it.
