Forest

The Forest is a big wood near Mattis's Fort where Ronja loves to play and have fun with Birk Borkason, her 'brother'. The forest is where Ronja discovered the Harpies, the Gray Dwarves, and Villain & Savage. The forest is very vast and wide, and, as shown in The call of Spring (song), is home to many creatures, such as foxes, bunnies, and deer.

As well as the regular forest fauna and the Grey Dwarves, the forest is inhabited by Rumphobs, small, furry, peaceful creatures who live in humanlike family groups, and Mirktrolls, translucent spirit-like creatures who dance around dolmens around spring-time.
