War Diplomat

A mericcup story where the Hairy Hooligan tribe threatens to avenge age old deaths and losses that the Highlanders caused. Upon hearing this, the King makes a decision: send a representative to Berk so that they can finally bury the hatchet. And axe. And mace and whatever other weapons the Vikings are threatening to raise against them. So they send the Princess, much to her outrage, to spend a month in Berk to settle the feud between the lands and familiarize their people.
Except, the Princess seems to be spending an awful lot of time with the chief's son, the lords have noticed, and there are rumors of an uprise among them.
