 He is sent alongside Hearth by Mimir to watch and protect Magnus.Though he keeps it up for two years, the task fails when Magnus is killed, but Blitz continues to look for him until they are reunited in Valhalla.As a dwarf, Blitz is sensitive to sunlight and will slowly turn to stone if exposed too much, which is why he always wears a copious article of clothing whenever there is sunlight, except in Folkvanger, in which sunlight is replaced by an aura radiated by Freya instead.
