Helheim is the sixth and farthest planet from Yggdrasil, orbiting at a distance of almost exactly 25 AU. It is a large ice giant, and the third largest object in the Yggdrasil system. Trace amounts of iodine in the atmosphere give the planet pinkish bands interspersed around the rest of the pure white to cyan clouds.
