Bjorn Fjord is a Concert Dwarf NPC found at the Red Blocks Amphitheater. Bjorn loves heavy metal, especially symphonic Viking Grindcore, but was disappointed by the lack of metal music played at Red Blocks. Therefore, he sends players on a mission to build and play the electric guitar instrument. As a reward, Bjorn teaches players a new dance move, claiming that the metal gods were pleased by the performance.
