The souls of the forest
As the souls of the forest, tree trolls offer the birds and smaller creatures of Rulantica a home. Generally speaking, tree trolls are described as very nurturing creatures who are particularly interested in the safety and well-being of the smallest creatures. They resemble huge trees and this means that they provide shade in summer.
According to legend, they were also relocated to Rulantica by the trickster god Loki. However, it is not clear where their actual home is in the nine worlds of Nordic mythology as it appears that such gentle, loving and nurturing beings as the tree trolls of Rulantica cannot be found in any other world.
