Well, Ymir was born from the void in Norse lore. Ymir's body was used to create the world as we know it in the mythology. For example, the mountains were made from her bones, the seas from her blood. Her back story is crucial as it sets the foundation for the entire Norse cosmological view.

This origin story is fundamental in understanding the Norse view of creation and the relationships between different elements in their cosmology.
