Lore

The Rune of the Mountain King is a relic of ancient times, when the trolls ruled the lands under the mountains. It was forged by Dovregubben, the greatest of the troll kings, who carved his own essence into the stone. He used the rune to command his subjects, to challenge his enemies, and to shape the earth to his will. The rune was a source of awe and fear for all who beheld it, for it granted Dovregubben the strength and stature of a mountain.

The rune was not always in Dovregubben’s possession. He once gave it to one of his strongest warriors, a powerful jotun named Jarl. Jarl was loyal to Dovregubben and fought by his side in many battles. He proved himself worthy of the rune by single-handedly defeating a dragon that threatened to destroy the mountain. The dragon was a fearsome beast with scales, claws, and breath of fire. Jarl faced the dragon in a fierce duel, using his strength and courage to overcome it. He brought the dragon’s scales to Dovregubben as a trophy, and Dovregubben acknowledged him and gave him the rune as a sign of his respect and recognition.
Jarl cherished the rune and passed it down to his descendants, who became known as the Jarlsons. The Jarlsons were respected and feared among the jotuns, for they inherited Jarl’s might and valor. They also inherited his loyalty to Dovregubben, and they swore to serve him as their king. The rune remained in their family for generations, but it's current whereabouts are not known.
