Lore

Skofnung was the blade of the legendary king Hrolf Kraki. It was renowned for its supernatural sharpness, the hardness of its steel, and for the fact it was imbued with the spirits of his 12 most faithful berserkers. It later showed up in multiple different sagas, usually as a result of some new hero plundering it from Hrolf’s tomb for one purpose or another.
