Beiwe brings greenery to the Arctic.
As a Spring and Sun goddess, she has a special association with the fertility of plants and animals. Reindeer are her favoured creatures and she travels with her daughter Beiwe-Neida through the sky in a cart made of their antlers.
The Saami apparently called on Beiwe for help with the insane. A handy deity to be friends with in the 21st century.
