Flashburn is an excellent swordfighter who ran a school named, Flashburn's School of Swordfighting.
Meeting Excellinor the Witch
20 years before the events of How to Steal a Dragon's Sword, Flashburn met Excellinor the Witch, who blackmailed him into searching for the Crown of the Wilderwest, which she knew was hidden under his school.
Hiccup, Fishlegs, and Camicazi found Flashburn in a spider-web underneath his school after they had been sent by the witch to find the crown. However, in all his time down underneath his school, Flashburn had become a broken man. He had lost all hope of ever getting out or finding the crown.
Flashburn holds a proud stature (being a professional sword-fighter), his hair is straight and blonde, that is slightly curved around the ends. Like most vikings, he wears a proud viking helmet with slightly twisted horns.
