Ymir is a planet located in an Unknown Globular Cluster far outside of Systems Commonwealth space. Its surface is described as a "fiery hellhole." Its moon, Burrie, is, in contrast, icy and collides with an aurora every 800 years. The Andromeda received a signal from the Moon, and went to investigate.
In Norse mythology Ymir is a frost giant, the first and greatest of the race. After being killed by Borrs, his body becomes the foundation of the whole world, his skull the heavens, his blood the oceans and his flesh the earth.
