Svartalfheim is the third planet from Yggdrasil. It is a rocky planet with a tenuous atmosphere, and is the smallest of the six planets at a mass of just 0.1 Jotunnheims. Svartalfheim’s miniscule atmosphere and distance from Yggdrasil leads to extremely low temperatures on the surface of the planet, with some areas nearing absolute zero.
