Muspellheim is the first planet from Yggdrasil. It is a terrestrial planet covered entirely in scorching deserts with evidence of geologic activity below the surface. Muspellheim has a smaller mass than Jotunnheim but has a similar radius, it is the second smallest planet in the Yggdrasil system. Muspellheim has no natural satellites. Muspellheim has a small atmosphere, only around 5% that of Jotunnheim, meaning it reaches extremely high temperatures due to its close proximity to the Yggdrasil.
